PROCEDURE FOR PROGNOSIS OF WEAR RESISTANCE OF HARD ALLOY CUTTING TOOLS Russian patent published in 2011 - IPC G01N3/58 

FIELD: machine building.

SUBSTANCE: resource of trouble-free operation of given cutting tools depends on intensity of diffusion processes in zone of contact with machined material. Surface structure of hard alloys greatly influences a value and direction of the said destructive phenomenon. Prognosis and control of wear resistance of cutting tools are carried out with consideration of value of complex force coefficient and concentration of base active centres - pH obtained at crumbled hard alloy mass. The procedure is based on close correlation between surface properties of crumbled hard alloy mass: value of force coefficient and concentration of acid-base active centres -pH and wear resistance of hard alloy cutting tools. Wear resistance of hard alloy cutting tools of the said group increases, when pH of crumbled hard alloy mass decreases.

EFFECT: upgraded accuracy and reduction of labour input at prognosis of wear resistance of tungsten-titan-cobalt, of group of applicability P, of cutting tools.
