AbstractTitanium based materials have wide range of applications at elevated temperatures including highly oxidizing and corrosive service conditions. Even though natural oxide film of titanium is very stable at room temperature and resistant to corrosion and oxidation, it is very brittle at temperatures higher than 650°C. Therefore, a protective layer at the surface would provide increased lifetime and performance for titanium based materials [1, 2]. For this purpose various methods including Al films sputtering, magnetron sputtering, pack cementation, pack aluminizing have been researched so far. Amongst these methods, hot dip aluminizing is a promising method for coating titanium materials as it is a simple, quick and inexpensive alternative with respect to the other methods [3,4].
