A new approach to the creation of composite wear-resistant coatings is proposed, which consists in realizing the advantages of combining the effect of mechanical nanocrystallization and mechanochemical reactions in the near-surface layers treated with ultrasonic impact treatment (UIT) in chemically active and inert media. This fundamentally distinguishes the proposed technique from the known methods of synthesis of bulk composite materials and provides more effective, compared to heat treatment and standard UIT schemes, surface hardening.
Showing an increase tribotechnical characteristics of titanium alloys in terms of friction without lubrication, abrasion wear, heat resistance, corrosion resistance the surface after diffusion saturation with nitrogen, carbon, oxygen, chromium, aluminum.
The possibility of intensification of diffusion saturation by introducing into the reaction space activators and activation of surfaces prior Magneto-abrasive treatment that is saturated. This reduces the saturation temperature of titanium and its alloys to 550-900 0C saturation and reduce time to 2-3 hours.
