Abstract

Laboratory exposures that simulated the oxidation-related attack in natural gas-fired reciprocating engines were conducted on Ni-Cr alloys with and without aluminide coatings. Exposure of uncoated NiCr alloy specimens to humid air at 800°C resulted in a mass loss due to CrO ₂(OH) ₂ evaporation and internal oxidation. Both model and commercial aluminide coatings reduced the amount of attack. The reaction products and Al interdiffusion were evaluated.
