Colour

Most GLISS-COAT layers are mattdark grey in colour, as plated.

Under compressive stress they take

on a shiny appearance and their

coefficient of friction decreases.Alternative colours are available

at customers special request.

Frictional behaviour

Optimum friction behaviour,

especially for aluminium,

magnesium and titanium alloys,

can be achieved by the application

of the GLISS-COAT process

variant 2000 and the use of anodic

intermediate layers (HART-COAT ,

anodising, KEPLA-COAT ,

MAGOXID-COAT ).

The service life and the coefficient

of friction of a GLISS-COAT hard

film depends on the type of coa-

ting and on the hardness

characteristics of the material to

which it is applied. Ideal friction

characteristics are fulfilled when

the coating is applied to two hard

metal surfaces which move against

each other with a uniformly app-

lied medium pressure and at

a comparatively high speed.

Powder coating is an electro-static

coating process during which elec-

trically charged paint particles are

applied, by means of a spray gun,

to the surface of a metallic work-

piece that is grounded.

The impinging particles generate

an opposite electric charge which

affects the adhesion of the paint

particles to the surface.

CED

www.ahc-surface.com

What is CED?

These paint particles are attracted

to the workpiece on which they

deposit and form a uniform film

across the part. Subsequent to the

application of the paint layer a

heat treatment (baking) is carried

out at 180 to 220 C.

CED (cathodic electro-deposition)

is a process during which the

workpiece to be coated is

negatively charged and then

immersed into a paint bath with

positively charged paint particles.

Advantages of CED

In combination with the use of

ultrafiltration technology, the high-

ly-automated coating

process offers an economically

advantageous use of paint

materials.

One of the benefits is that every

crevice and corner is coated until

the film reaches the specified layer

thickness. Thus, a uniform coating

thickness over all the parts is

achieved. CED layers provide good

corrosion protection and high

impact strength.

CED

CED fields of use

Cathodic electro-deposition

techniques are used in the

automotive and mechanical

engineering sectors to provide

corrosion protection to a wide

variety of components, e.g.,

stamped parts.

CED increases the stone impact

resistance and, as a consequence,

is often used for grids which

protect commercial vehicles

against falling rocks. The coatingprocess is well suited to complex

shaped parts due to the uniform

coating thickness produced.
