Results from an ongoing study of the high temperature oxidation of intermetallic compounds in the Ti-Al system are presented. The oxidation behavior of alloys based on TiAl (y) has been found to be extremely complex depending on temperature and atmosphere composition. Protective alumina scales are formed in pure O2 up to a critical temperature above which a mixed Ti02/A1203 scale forms and grow...

In order to improve the oxidation resistance of ferritic stainless steel, it is possible to deposit a protective coating on steel substrate. In this research through the usage of pack cementation method a coating of titanium was applied on the surface of AISI 430 stainless steel. Scanning Electron-Microscopy (SEM), Energy- Dispersive X-ray spectrometry (EDAX) and X-ray diffraction (XRD) were us...
