Magnaflux is sad to announce the death of Vilma Holmgren,
who died of cancer on Saturday, September 30, 2006. Vilma wasone of the most respected members of our organization and thenon-destructive testing community.
Vilma graduated from the Mapua Institute of Technology,Manila, with a Bachelor of Science degree in chemistry, in
1977. In 1984, she went on to obtain her
masters degree in chemistry from DePaulUniversity, Chicago, and then in 1988 shegraduated with her second masters degree, inbusiness administration.
Vilma joined Magnaflux in 1979. Hermany accomplishments include two patents
and the American Society for NondestructiveTesting (ANST) Fellow Award for her signifi-
cant contributions to the advancement of NDT.She was a valuable contributor to the ASNTHandbook through articles and papers on pen-
etrant and magnetic particle inspection. Vilmawas the Secretary of the ASNT
Chicago Section, held positions ofChair, Vice Chair and Secretary
of ASNT, PT/MT committee,chaired the Penetrant Section ofASTM 07.03, and was an active

Looking at our industry, there are two primary categories of aqueous cleanersAerospaceSpec cleaners and General Use cleaners. For those who are working with aerospace parts and
assemblies, the distinction is obviousonly qualified products can be used. But the line blursif you dont work with OEM specifications on a daily basis. What exactly makes an aqueous
cleaner an Aerospace Spec Cleaner?To begin with, an Aerospace Spec Cleaner is formulated with OEM specifications and
testing in mind. It is not enough to simply clean the surface the chemistry must be compat-ible with a wide variety of metals, alloys, and non-metallics. While a general-purpose cleanercan use cheap, effective inorganic chemistry to scrub oils and grease, these chemicals can
damage aerospace materials. Surfaces of titanium, anodized aluminum, and electroplating allneed specialized chemistry to ensure thorough cleaning while protecting the surface finish.
Of course, cleaning power and surface protection are only part of the formulation. Thechemistry must be tailored to prevent any residues or films from building up on the parts.
These would not only affect paint and coating adhesion, but would promote corrosion andlead to stress failures down the line. As with any chemical, the environmental impact andhazard rating of the cleaner must be considered as well. This includes global regulations
on VOCs and HAPs, as well as new end-of-life regulations and disposal requirements.Recyclability is a factor as well, since aerospace assemblies can require large cleaning tanks,
and recycling the cleaner will mean real in-use cost savings.It is not enough simply to formulate a cleaner for use on aerospace parts. The cleaner
must also pass rigorous testing in laboratory and production situations. Lab tests are usuallyconducted at independent, accredited laboratories, with results submitted directly to OEMand certifying bodies. Production and service tests are typically performed at the OEM fac-
tory or at an authorized service center under controlled conditions to objectively rate perfor-mance. The specific tests vary, depending on the specific OEM requirements, but generally
follow the same course. The table onthe next page shows a typical list of
laboratory tests needed for approval.Completing the lab and produc-
tion testing can take up to a year,
depending on the specific OEMrequirements. But a true Aerospace
Spec Cleaner would be qualified notonly to one OEM specification, but
to as many as possible. That way, ifa shop is handling parts for a variety
of clients, all the requirements can bemet using a single cleaning process.
You can find the solution to allthese challenges in the Daracleanline of Aerospace Spec Cleaners.
Daraclean cleaners are formulatedto handle the special requirements
of the aerospace market, and have abroad spectrum of OEM spec approv-als. Even if your application does not
require strict OEM spec approvals, youcan be confident that Daraclean products are the best aqueous cleaners availablesuperior
cleaning performance, multi-metal safe, high corrosion protection, and recyclable.

Though her official title was MaterialsBusiness Unit Manager, Vilma Holmgrensunofficial title was Miss Magnaflux. As
Materials Product Manager, I reported toVilma and to be honest, she was a tough
boss. She was not tough because of anynegative traits or actions, but because she
had extremely high expectations of everyoneat Magnaflux. She demanded nothing
less than your VERY best. Vilma wasvery intelligent yet very compassionate.She truly respected and cared for me, as
a person and it showed. When she saw
that I could do better, she felt it was herjob to make sure I did my best, plainand simple. That was just how Vilma
was. She was one of the most humblepersons I have ever met. No one everknew exactly how many awards, patents,
master degrees or accomplishments shehad earned because it was not in her to
talk about herself.Vilma was our safety net for both the
materials and equipment departments.If a customer had a question about some
obscure product or certification we onlyhad to ask Vilma. Either she would knowthe answer from memory or she would
quickly look it up in that file cabinet ofhers. I never actually looked inside that
file cabinet but I swear it must have beena black hole, which produced the filethat had the answer to any question.
I would make bets with coworkers onquestions I thought she would never
have an answer for, like the TasmaniaAir Force specification for inspecting
landing gear. After a few moments at her
file cabinet out comes this yellowed filewith the information.
When you work with someonelike Vilma its easy to take them for
granted. You think as long as there is aMagnaflux, Vilma will be here. But we
did lose her and after getting over thepain we have begun to realize thingswill be alright. Because of the demands,
guidance, and concern that Vilma had
for all of us we are better people and a bettercompany. It may take more of us to fulfillthe legacy she left, but to honor her we will
continue to strive for our very best.

In general, to function properly the
particles composing the medium in both
the wet and dry method should fit the
following criteria:
Nontoxic Correct particle size for the application
Ferromagnetic
Free of contaminants
Possess high permeability
Possess low retentivity
Provide high visibility
The one factor not listed above, but very
important, is durability. The particle must
be able to withstand constant circulation
within the pump of the magnetic inspec-
tion bench or mechanical agitation and
still maintain its integrity. The success of
magnetic particle testing is dependent upon
the selection of the proper material and
method to conduct the test. When the wet
method is used, the medium concentrate
is mixed with a liquid (light oil, kerosene
or water) to make a bath which is then
applied onto the surface of the part either
while the magnetizing current is flowing for
the continuous method or the medium is
applied after the magnetizing current is shut
off for the residual method.
Particle Shape
If the particle has a spherical shape it will
have excellent mobility but will not be
strongly attracted to the leakage field. On
the other hand, a long, slender particle
may be strongly attracted to the leakage
field due to its pronounced north and south
poles but will have lower mobility. These
two opposing characteristics are overcome
by blending particles of different shapes. In
actual use, particles never act as individuals.
Due to the fact that they are magnetized in
use and the material has some retentivity,they become actual tiny magnets. These
particles are drawn together as a result of
their retained magnetism to form clumps or
aggregates of particles. The particles tend
to act as a unit when applied to the surface
of a part for magnetic particle testing. The
speed and extent to which this process takes
place increases with the rententivity of the
particle material. Agitating the suspension
breaks up the aggregates, but they begin to
form again as soon as agitation ceases.
Causes of particle breakdown
The particle used in magnetic inspection
is a combination of fusing iron oxide, a
unique resin, and pigment (fluorescent
or visible). Particles used in a magneticinspection bench, in most cases, are re-
circulated using an impeller driven pump.
Over a period of time this action will cause
the pigment to detach from the iron oxide
material. The lack of both bath and equip-
ment maintenance will cause possible prob-
lems within the bath. Defective pumps will
cause an increase of particle breakdown.
One common mistake is to replace a defec-
tive pump with one that has a higher rpm
rating. This naturally will cause the par-
ticles to break down faster. It is advised that
you call Magnaflux or an authorized service
center when replacing any part on one of
our units. Bath contamination with acid or
alkali from a pre-cleaning step or process
will cause degradation of the particles.
Also, processing hot parts may raise the
bath temperature above acceptable levels
(100 to 120) which will soften the resin.
The Results of Particle
Breakdown
When the bond of the iron oxide particle
and pigment has deteriorated, increasedbackground will be observed. This increase
background could mask indications and
some discontinuities could be missed. Also,
frequent bath replacement causes increased
material and labor costs which will affect
revenue margins.
Preventative Measures
Contamination can be minimized by keep-
ing the bath covered when not in use and
monitoring the bath concentration using
the correct centrifuge tube. Using a durable
material will also help in preventing prob-lems in the magnetic particle inspection
process. Magnaflux offers the most reliable
materials on the market for wet method
inspection, for both fluorescent and visible
applications. Extensive testing has proven
that Magnaflux particles are the most dura-
ble in the industry. Here is a list of these
materials, with the special characteristics
of each.
Magnetic Particle Breakdown in the Wet Application Method
FLUORESCENT
14A Fluorescent PowderConcentrate. This is the most widelyused of the fluorescent materials. It fluoresca bright yellow-green and features high sensitivity, high brightness, and easy handlingproperties. It is designed for suspension inoil, but can be used in water when combinewith the proper water conditioners, WA-2Bpowder which contains wetting agent, cor-rosion inhibitor, antifoam and WA-4 liquidwhich contains wetting agent and corrosioninhibitor. You can also use AX-52 corrosioninhibitor as an additive.
14A Redi-Bath Pre-measuredLiquid Concentrate.Contains 14Apowder, wetting agent, anti-foaming agentand rust inhibitors in a graduated plasticbottle which holds 27oz (800ml), enough tmake up a 10 gallon water bath.
20B Fluorescent PowderConcentrate. This powder is identicalto 14A but includes the proper amountof water conditioners. It is for water
baths only.
MG-410 Fluorescent Powder.Larger particles than the 14A but brighterUsed for larger discontinuities, especiallyin the steel industry. Used in both oil andwater baths
MG-3410 Fluorescent Powder.The powder contains MG-410 and waterconditioners. Used in water baths only.
VISIBLE
7C Black Powder Concentrate.This is an oil-suspendable powder. It isespecially suited for finding fine crackson polished surfaces, such as bearings andcrankshafts. It can be used in a water bathwith the proper proportion of water-conditioners.
9C Red Powder Concentrate. This a reddish brown oil-suspendable powder. is similar to 7C but gives improved contrason gray, black or dark surfaces.
