Abstract
The paper analyzes the surface structure and properties of commercially pure VT1-0 titanium nitrided in the plasma of a low-pressure gas discharge produced by a PINK plasma generator. The analysis demonstrates that the friction coefficient of the nitrided material decreases more than four times and its wear resistance and microhardness increases more than eight and three times, respectively. The physical mechanisms responsible for the enhancement of strength and tribological properties of the material are discussed.
Highlights
Titanium and its alloys are widely used in industry and medicine due to their low specific weight, high corrosion resistance, and biological compatibility [1]
The surface of the specimens was subjected to nitriding in the plasma of a low-pressure gas discharge produced by a PINK plasma generator which provides the possibility to increase the plasma density at comparatively low discharge operating voltages, vary the discharge current irrespective of the latter and of the pressure in the working chamber, and produce the plasma with no microdroplets [4]
The surface hardening of both the face and back of the Ti specimens nitrided at 650 °С is damping (Fig. 1, curves 5 and 6)
Summary
Titanium and its alloys are widely used in industry and medicine due to their low specific weight, high corrosion resistance, and biological compatibility [1]. The materials display low hardness and low wear resistance, and this is a barrier to further extension of their applications. One of the promising ways to enhance the functional properties of materials, including titanium and its alloys, is their diffusion doping [2] which nitrogen is often used for. Nitriding considerably increases the surface strength and wear resistance of materials, make them less prone to tears, and provide their high cavitation and corrosion resistances in atmosphere, fresh water, and vapor. The aim of the present study is to analyze the surface structure and properties of commercially pure titanium subjected to low-temperature nitriding
