FIELD: measurement equipment.
SUBSTANCE: thickness of coating, hardness and elasticity modulus of material of the base are determined by means of known methods. Loading (implementation) of diamond pyramidal indenter is performed into the product to the depth exceeding the coating thickness. The diagram of load value variation with increase in implementation depth is recorded, as per which relationship between the change of relative surface microhardness and relative thickness of the coating is built. An ascending branch of relative hardness variation curve is approximated in the form of mathematical dependence and modulus of normal elasticity of the coating material is determined as per results of joint numerical solution of the approximated equation and the equation describing theoretical hardness of a model layered body in the same area of indenter implementation depths.
EFFECT: simplifying the method for determining elasticity modulus value of thin coating material.
