Abstract
As is generally well known, though titanium and its alloys have high specific
tensile strength, excellent corrosion resistance, etc., they have not been widely
used until now mainly due to their extremely high processing cost. Therefore, it
is considered that the above barrier will become smaller if it is possible to
improve the mechanical properties of Ti-alloys by applying surface treatments on
them. The purpose of this paper is to improve and to evaluate the mechanical
properties, especially fatigue strength of about 6 lunds of surface-treated Ti-6A1-
4V alloys. That is, surface treatments by 2 kinds of plasma, 3 kinds of DLC
