FIELD: estimation method for estimating mechanical properties of thin coatings and layers with uneven property distribution.
SUBSTANCE: method involves determining microhardness value on sample surface by measuring dimensions of revived indentation during changing force applied to indenter; drawing graph presenting hardness dependence on indentation depth; determining integral microhardness; drawing graph representing integral microhardness; marking out points characterizing hardening and weakening dynamics change; determining value of critical load leading to qualitative layer capacity change from above points.
EFFECT: increased estimation reliability.
