METHOD OF DETERMINATION OF ADHESION OF FILM TO SUBSTRATE

摘要

FIELD: material testing technology. SUBSTANCE: proposed method consists in applying breaking-off load to coat of base for determination of strength of adhesion of film to substrate. For forming the breaking-off load, use is made of second coat, for example carbon diamond-like coat obtained by vacuum-arc method whose internal stresses exceed internal stresses in coat under test. Adhesion of film to substrate is judged from thickness of second coat at which ply separation takes place. EFFECT: simplified procedure; enhanced accuracy. 2 cl
