Paper Title:
Surface Modification of TA18 by Thermal Oxidation
  Abstract

TA18 alloy was used as the base material to investigate the effect of thermal oxidation (TO) on titanium alloys. The samples were subjected to TO treatment in a conventional muffle furnace at the same duration (210min) for different temperatures under air atmosphere. The results showed that an oxide layer comprised of rutile TiO2 and a small amount of Al2O3 were formed for samples thermally oxidized at 700°C and above, and both rutile and Al2O3 peaks increase with the treating temperature. The surface hardness increased significantly with the treating temperature due to the formation of a thin oxide layer and an oxygen diffusion zone in TO process. The wear test results showed that TO process can significantly improve the wear resistance, and the wear resistance is a function of the treating temperature, with 700°C being the optimum temperature to improve wear resistance of TA18 alloy for the duration of 210min.
