The suitability of selected austenitic stainless steels and hastelloy C276 alloys as substrates for thin film deposition using spray pyrolysis

Abstract

Abstract To detect the suitability of the American Iron and Steel Institute grade 304, 309, 310, 316L steels and Hastelloy C276 substrates for thin film deposition using spray pyrolysis, the substrates were pre-heated between 400–700°C and soaked for one hour. American Society for Testing and Materials standards A262-A, E and G28-A were then applied. The substrates of 304 heated at 400, 600–700°C, the 310 heated between 450–700°C and the as-received 310 were not found suitable. However it was found that the 304, 309, and 310 substrates were suitable up to 550°C, the 316L up to 700°C and the C276 up to 550°C.
