Abstract

The results of experiments on low-energy implantation of nitrogen ions into VT1-0 titanium alloy are presented. Processing was performed by a nitrogen ion pulsed beam obtained using a ballistic ion focusing system. An ion source was a nitrogen plasma of the non-self-sustained gas arc discharge with a thermionic cathode. It has been shown that when the specimens are processed in such a system, hardness of the surface increases from 1.5 to 2.5 times. In addition, the surface of the specimens undergoes ion etching which causes the formation of an etching cavity whose profile depends on the ion effect parameters.

Summary

Introduction

Increasing the working properties (hardness, wear resistance, etc.) of products made of titanium and its alloys is an important scientific and technical issue, in the solution of which aircraft and engine technology, automotive industry, space industry, etc. are interested. An ion implantation method has been widely used It is realized by transferring added energy (tens or hundreds of kiloelectronvolts) to ions into the surface of the substance [1]. This method is limited by the magnitude of the ion projection distance in the surface (tens of monolayers). Another widely used method for changing elemental and phase composition of the surface is a diffusion saturation method [2]. An important task for realizing the processes of obtaining modified nitrogen-containing
