Effect of Boriding Temperature on Mechanical Properties of Pure Titanium Using Powder Boriding Process

Abstract

Titanium is used in various fields from aircraft and automobiles to implants as a lightweight, corrosion-resistant material and high specific strength. Titanium is known to have poor wear resistance, which can be improved by forming a hardened layer on the surface, such as by nitriding. Boriding is one of the methods to generate a hardened layer on the surface, but there are few reports on the application of boriding to titanium and its mechanical properties. In this study, boriding with boron powder was applied to pure titanium to investigate the improvement of mechanical properties. As a result, higher hardness and wear resistance were obtained than a pure titanium.
