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 adhesion processes in zone of contact with machined material. Acid-base properties of surface structure of hard alloys greatly influence a screening process 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 at surface crumbled structure of hard alloy cutting tools. The procedure is based on a correlation between properties of surface crumbled structure of hard alloy - 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 grows at increase of pH at surface crumbled structure.

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