The MTR3 is an equipment designed for t charac cterizing the su urface mechanical properties of thin films, substrate influence, and coatings and so d on. Specifically,theabov vementionedc characterization nit is car rried by mean of two fam ns milies of alrea ady popula tests in scientific world. They are: mic ar cro indent tacin test (ISO 14577:2005 Meta allic mater rials.
