Abstract :
On the basis of investigations performed, the multifunctional plant for ion-plasma technology was developed. The multifunctional unit realizes: wear-resistant coating/plating (electric-arc vaporizers, magnetron systems); surface layer strengthening by implantation of ions, nitrogen ions, cyanide, ionic alloying and ionic modifications; vacuum laser treatment for engineering materials, subjected to critical oxidation under strengthening in the air or in a protective medium; and combined strengthening consisting of two or three of the mentioned methods of strengthening. The unit allows: plating with pure metals, nitrides, carbides, carbonitrides, both monolayers and multilayers with thickness 0.5-70 μm; and to increase wear-resistance of parts by 2-35 times, corrosion resistance by 1.2-16 times, maintain or reduces surface roughness, maintain or increases fatigue strength by 1.3-2 times, receive willing tribo-technical characteristics (antifriction and friction coating)
