FIELD: metallurgy.
SUBSTANCE: method of diffusion titanation of hard alloy products includes a preliminary products cementation and the subsequent diffusion saturation of their surface with titanium. After the said diffusion saturation with titanium, aging is conducted at the temperature of 300-800°C for 60-120 minutes, and pre-carbonization is performed at the temperature of 1,100-1,250°C for 10-20 minutes.
EFFECT: increased wear resistance and service life of hard alloy products in exposure to high contact stress, shock, and variable loads.
