| Abstract Scope |
In recent years, tantalum is being increasingly researched as a replacement for hard chromium coating on steel substrate for military applications. This study focuses on high-temperature oxidation as a potential recycling route of such composite material. Several oxidation tests were carried out in muffle furnace and thermogravimetric analyzer to study the oxidation behavior and oxidation kinetics at various temperatures and times. A comparative study was also carried out on different grades of steel substrates to determine the effect of coating, substrate and deposition technique on oxidation behavior of tantalum coated steel composite. The results indicate temperatures around 700C is optimum for separation, but optimal time may differ depending on the type of substrate and thickness of coating. |
