METHOD OF PREDICTION OF WEAR RESISTANCE OF HARD ALLOY CUTTING TOOLS Russian patent published in 2019 - IPC G01N3/58 

FIELD: technological processes.

SUBSTANCE: invention relates to metal forming and can be used for forecasting and control over carbide tool durability in production, application or certification. Method of prediction of wear resistance of hard-alloy group of applicability P of cutting tools on selected initial parameter consists in that testing is carried out for change of value of initial parameter from properties of surface and volume structure formed during manufacture of hard-alloy cutting material, performance of reference tests for wear resistance during cutting of materials, which cause intensive diffusion wear at optimum or close to it cutting speed, construction of reference-correlation dependence "wear resistance – initial parameter", statistical control of only value of initial parameter of current batch of hard alloy cutting tools, wear resistance forecast for current batch of hard alloy cutting tools on the basis of dependence. Initial parameter used is the sum of diffuse reflection coefficients of polychromatic light in the wavelength region λ=490±20 nm and λ=700±20 nm from polyoxide formation, formed on surface of hard-alloy cutting tools at their heating after testing for wear resistance in electric furnace, with reduction of which wear resistance of hard-alloy cutting tools of application group P increases.

EFFECT: improving accuracy and reducing labor intensity at prediction of wear resistance of hard alloy cutting tools.
