FIELD: measuring equipment.
SUBSTANCE: coating thickness and hardness of the base material are determined by the known methods, loading (introduction) of the diamond pyramidal tip is performed into the planar surface of the uncoated or coated product, having a known thickness, to the depth exceeding the coating thickness, the charts of the loading change are recorded with increasing the penetration depth, according to which the dependence of the parameter change is plotted, characterizing the ratio of the penetration depth squares into the coated and uncoated surface from the relative penetration depth defined for the same loading, and compared with the same parameter values calculated on the theoretical dependences functionally dependent on the magnitude of the contact elastic modulus of the layered body including the elasticity modulus of the coating material, and the normal elasticity modulus of the coating material is determined on the results of the maximum match of the parameter values obtained from the experiment with a set of parameter values obtained by the theoretical calculations, in the range of the relative indentation depths of 0.2 to 1.0.
EFFECT: improving the accuracy and definition objectivity of the coating material elasticity modulus on the product.
