The application of strengthening vacuum ion-plasma treating for the surface layer of constructional metal materials in mechanical engineering and the features of its formation

The paper lays bare the constructive scheme of technological effects of gas and metal plasma flows while exploiting VIP treating to process structural materials and structural changes the surface layer undergo at the technological stages of VIP treating. Moreover, it considers the complex system to ensure the operational properties of structural materials during VIP treating. The application of VIP treating turns out to be exceptionally efficient to reduce damages of the friction unit surfaces under fretting conditions. (paper)
