Advancements in Boriding Techniques for Enhancing Titanium Alloy Performance

As an important structural material in the 21st century, titanium and its alloy have the advantages of corrosion resistance, high melting point, small density, high specific strength, no magnetism and biocompatibility, but low surface hardness, poor wear resistance, large friction coefficient, poor high temperature oxidation resistance and other defects seriously limit its application scope. Boride-titanium intermetal compounds can effectively improve the surface hardness and wear resistance of titanium and its alloys. This paper summarizes the research status of titanium alloy embedding permeability, surface molten salt electrolysis boron permeability and plasma boron permeability, and discusses the process parameters and mechanism in the process of boron permeability.
