FORECASTING OF CARBIDE CUTTING TOOL WEAR RESISTANCE Russian patent published in 2017 - IPC G01N3/58 

FIELD: metallurgy.

SUBSTANCE: testing for input parameter change due to properties of surface and volume structure, formed during manufacturing of carbide cutting material, reference wear tests during cutting of the materials resulting in intensive diffusion wear at optimal or close to it cutting speed, plotting of the reference - correlation relationship "wear resistance - input parameter", statistic monitoring of only input parameter of the current batch of the carbide cutting tools, forecast of wear resistance for current batch of the carbide cutting tools based on the relationship. Volume concentration value of oxide compound is used as initial parameter based on cobalt and tungsten -_CoWO4, forming a part of complex surface polyoxide formation, formed on the surface of the carbide samples when heated, with the decrease in concentration of the double oxide compound based on cobalt and tungsten, wear capability of carbide cutting tools of group P increases.

EFFECT: predicting the wear resistance of carbide tungsten - titanium - cobalt cutting tools of the applicability group P is a higher accuracy and lower labour input of forecast of carbide cutting tools wear resistance.
