Long-term degradation behavior of slurry aluminide coating on Super304H stainless steel at 650 °C
Source abstract
Abstract
Abstract An engineering-favored slurry aluminide coating was prepared on the inner wall of a Super304H boiler tube. The degradation behavior of aluminide coatings was investigated at 650 °C in static air for up to 10 kh. The inward diffusion of Al dominated the degradation mechanism. Even though a phase transformation from β to γ' occurred, the Al concentration was sufficient to meet the minimum quantity required for alumina growth after 10 kh. A life prediction model of aluminide coatings with Al content as the main index was proposed according to Fick's second law of a diffusive process.
