Title: Surface treatment method for titanium material
Inventor: YAMADA SHIGEKI
IPC: C23C8/10
Filed: 2002-09-26
Abstract: <P>PROBLEM TO BE SOLVED: To provide a surface treatment method for a titanium material having wear resistance and high fatigue strength in which treatment stages are reduced and by which stable oxidation prevention is possible.  <P>SOLUTION: In the oxidation treatment for imparting wear resistance, nitriding treatment is performed to a part requiring fatigue strength, so that the diffusion of oxygen can stably sufficiently be prevented. Thus, though the reduction of its fatigue strength has been compensated, e.g., by the wall thickness or the like of the material, it is made needless, and a thin, lightweight titanium member in which wear resistance and high fatigue strength can be combined is obtainable. Further, only the part requiring fatigue strength is subjected to nitriding by using a nitriding chamber, so that processes are reduced, and also, continuous treatment is made possible. Thus, the treatment is extremely inexpensive, and is excellent in productivity.  <P>COPYRIGHT: (C)2004,JPO
