| Summary: | Includes abstract. === Includes bibliographical references (leaves 123-128). === Oxygen Boost Diffusion Hardening (OBDH) is a cost effective surface modification process which can greatly improve the tribological properties of titanium components. This report deals with the oxygen diffusion treatment of Ti-6Al-4V (Ti-64), the most commonly used titanium alloy, to rank various treatment conditions based on their ability to increase the surface hardness and wear resistance. Modes of wear were evaluated using SEM micrographs and elemental analysis of worn surfaces and wear debris. |
