LASER CONTRASTING METHOD AND APPARATUS FOR CARRYING OUT A CONTRASTING METHOD

摘要

The invention relates to a laser contrasting method, wherein the surface of a specimen that is intended to undergo materialographic analysis is partially subjected to a polishing operation and subsequently worked with at least one laser beam in such a way that, as a result of the thermal expansion of the grains of the worked surface of the specimen, a microstructure that can undergo materialographic analysis, in particular with the aid of an optical microscope, is obtained.
