FIELD: testing engineering.
SUBSTANCE: method comprises pressing the pyramidal indenter into the cross-section of the coating or material layer until a mark is formed when its diagonals are oriented orthogonal to the direction of residual stress, recording the value of pressure, measuring the area of the mark, and determining the residual stress from the formula proposed.
EFFECT: expanded functional capabilities, reduced labor consumption, and enhanced precision.
