Conclusions

It has been established that the cementing phases of P/M chromium carbide and titanium carbide hard metals can be superficially hardened by thermodiffusional impregnation with phosphorus. Treatment of these alloys for 3–7 h at 1000°C in an alumina filler containing 30–70% of nickel phosphide and subsequent 1-h annealing at 400°C increase the surface hardness of their binder phases by 1.5–3 GPa. Thermodiffusional treatment doubles the wear resistance of KKhN35 alloy operating under hydroabrasive wear conditions.
