Study of surface layers obtained by copper ion implantation into a target of steel 30хгсн2а by auger Spectroscopy methods

Abstract

The relevance of the study due to the necessity of increase in the wear resistance of the tribological parts from steel 30ХГСН2А through the copper ions implantation. The leading method for investigating this problem is the examination of the implanted layers of the target surface made of steel 30ХГСН2А by means of auger spectroscopy making it possible to review the structure and distribution of the implanted ions comprehensively. The article presents the study results of copper, carbon and oxygen distribution regularities in the surface layers formed during copper implantation into the plates from steel 30ХГСН2А in the impulsive ions source. It has been established that in the process of copper implantation, a carbon layer with a thickness of ~ 50 nm is formed on the surface. It is shown that in the intermediate layer (up to 100 nm), the iron is partly in the oxidized condition. The possible mechanisms of the influence of surface layers structure formed in the result of copper implantation into the steel plate 30ХГСН2А on their tribological characteristics are presented. The article materials are of practical value in developing the technology for wear resistance increase of the various parts of the revolution shape used in aircraft movable joints.

Electron-Microscopic Examination of the Surface Layer of Titanium Alloys OТ4 after Ion Implantation

“…As follows from the work on the study of the mechanism of implantation by multicomponent ion beams [1][2][3], the implanted layer and the matrix (the actual alloy) itself is a physicochemical open system in which not only energy exchange but also substance takes place. And, in addition, this system is in highly non-equilibrium conditions.…”
