Reactions between Ti and light elements

Abstract

Light elements such as hydrogen, carbon, nitrogen, and oxygen interact with Ti and its alloys during manufacturing processes and in usage environments. These elements exhibit high affinity and high solubility in Ti as well as being interstitially dissolved, abundant, and inexpensive. Interactions between Ti and light elements are related to the reduction and refining process, alloy and surface design, microstructural control, and other functions. Thus, understanding interactions is necessary for constructing a reasonable Ti production process and expanding applications. The recent progress in our group on the interaction between Ti and light elements, including the experimental and computational approaches for the high-temperature oxidation of Ti alloys, preparation and antibacterial-activity evaluation of visible-light-responsive photocatalytically active TiO₂ layers formed by the surface reactions of Ti, and oxygen removal (deoxidation) from Ti melts using hydrogen plasma, are reported in this paper.
