| Abstract | ||
| Experimental studies have been made to determine the oxidation be havior of several coatings system on commercial stainless steel alloy (S.S. 321). The oxidation kinetics of a single stage coating such as Aluminized and Nickel - Aluminzed alloy have been under atmospheric studies pressure at 1000Co using a thermal cyclic oxidation. X-ray technique was used to identify the coating structure and oxide scale. Most coating use to enhance the formation of protective oxid scale, the results showed that non of the coating was totally resistant to cyclic oxidation. But Nickel–Aluminized coating, exhibited the greatest resistance to oxidation . The superiority protection of Nickel – Aluminzed coating can be due to the formation of NiO and Al2O3. | ||
