AbstractThe cyclic oxidation behaviour of Pt modified AlSiY coating and AlSiY coating at 1100 degrees C were investigated. The results showed the Pt modified AlSiY coating had lower oxidation rate than AlSiY coating. After 1 cycle, minor theta-Al2O3 was observed in AlSiY coating, while only alpha-Al2O3 was found in Pt modified AlSiY coating. After cyclic oxidation, the surface roughness of Pt modified AlSiY coating was lower as compared. to AlSiY coating. Besides, the addition of Pt in AlSiY coating decreased the quantity and average size of TCP in the secondary reaction zone (SRZ) after cyclic oxidation. (C) 2016 Elsevier Ltd.
