Development of a combined technology for parts strengthening
Journal Title: Технічна механіка, Техническая механика, Technical Mechanics - Year 2017, Vol 3, Issue 3
Abstract
The aim of this work is to develop a combined technological process for improving the performance characteristics of units and parts with moving contacting surfaces. The process is based on metal surface property modification methods that use physical effects in the interaction of the surface under treatment with concentrated energy fluxes. Consideration is given to a possibility to treat the working surfaces of parts made of a high-strength titanium alloy using ion-beam and ion-plasma technology. All the elements of the technological process must meet progressiveness criteria. It is shown that the effect of factors that adversely affect the functionality and the fatigue life of parts may be significantly diminished or eliminated. Strengthening is achieved by successive or simultaneous use of ion-beam surface treatment, high-intensity low-energy nitrogen atom implantation, and the ion-plasma deposition of a finish functional nanostructured coating. This paper presents part 1 of the work, which is of problem description character. The final goal of the work is achieved with the development of plasma process devices. The results of the development of process devices and the optimization of their use in a process installation will be presented in part 2 of this work.
