In this work, was defined the influence of diffusion methods titanizing, titan-vanadium, titaniumvanadium chromizing, nitrogen-titanium-vanading, nitrogen-titanium-aluminizing on mechanical and cutting properties of plates of hard alloy VK6. Coatings were applied in powder mixtures under conditions of reduced pressure using activators. In some cases, samples before metallization were nitride in medium of dissociated ammonia. Established, that the flexural strength of coated alloy VK6 with coatings decreases in stabilization of values from baseline alloy. It is shown that the stability of hard alloy plates with coatings in cutting steel 12X18H10T initial resistance was higher in 5,6-11,0 times. Established the reduction of the minimum of relative wear plates with coatings and minimum shift towards higher cutting speeds. The most results showed nitrogen-titanium-aluminized coatings. For hard alloy VK6 with these coatings, minimal wear at sharpening of steel U10A decreased in 6.8 times and speed of the cutting speed increased from 80 m/min to 280 m/min compared with baseline.
