The hot corrosion behaviour of a platinum containing nickel based superalloy (RJM 2012) is compared with that of a similar alloy (IN 792 + Hf) without platinum. The results of burner rig testing at 800Β°C showed that the oxide scales on the platinum containing alloy were still very protective after 1000 h on test whilst the alloy without platinum was severely attacked after only 200 h. The influence of platinum on the degradation mechanisms is discussed.

## Abstract Cold rolled sheets of a nickelβbase superalloy are used in building gas turbine engines. After rolling to the final gauge, the sheets were annealed at 1180βΒ°C. Pickling of the sheets was carried out to remove the scale and the oxidized layer. It was observed that there was heavy inciden
The mechanical properties of a solution treated and double aged nickel -18% iron -18% chromium alloy (Inconel 718) were studied to assess its utility at temperatures in the ambient-to-cryogenic range. Uniaxial tensile property measurements using unnotched specimens at decreasing temperatures between
## Abstract Ni~3~Al metallic powder was prepared by the mechanical mixing of pure nickel and aluminium powders and deposited on a Niβbase superalloy namely Superni 75 by the shrouded plasma spray process. Hot corrosion behaviour of Ni~3~Al coated and uncoated superalloy specimens was evaluated in a
