Nowadays, long service life is often required because the environmental regulation and labor costs on repairing are expected to become increasingly severe and high. A promising approach to optimize both mechanical properties and corrosion resistance is the use of coating technologies. Titanium and titanium alloys are widely used for corrosion protection because they offer a high chemical resistance against various corrosive media due to a dense self-sealing oxide layer. This paper gives a general review on various surface modification technologies pertaining to titanium and titanium alloys including physical vapor deposition, magnetron sputtering, cold spraying, thermal spraying, and shrouded plasma spraying from the perspective of coating technology. Recent research work has shown that it is a more effective method by the protective titanium or titanium alloys coatings to provide improved corrosion resistance. The proper surface treatment expands the use of titanium and titanium alloys in the aggressive corrosion atmospheres. Some of the recent applications with a gas shroud to deposit titanium and titanium alloy coatings are also discussed in this paper.
