MICROHARDNESS MEASURING TECHNIQUE FOR THIN METAL COATINGS

摘要

FIELD: measurement technology. SUBSTANCE: measuring technique involves determining microhardness by size of recovered mark left by diamond indenter at two loads applied to the latter: 100 and 200 g. True value of microhardness is found from relationship between mentioned microhardness values. EFFECT: improved accuracy of evaluating true microhardness. 2 dwg, 1 tbl
