Abstract | A glass-based composite coating incorporating YSZ, corundum, and Ni3Al was prepared on IC10 superalloy with a sputtering Hf-modified Ni3Al bond-coat. Sealing effect of the glass-based top-coat and reactive elemental effect of Hf facilitated the formation of columnar alpha-Al2O3 at 1050 degrees C. Furthermore, a discontinuous gahnite interlayer formed at the alpha-Al2O3/top-coat interface due to interfacial reactions. However, because of the discontinuous microstructure of gahnite, the alpha-Al2O3 suffered durative attack by the active glass matrix, which caused severe internal oxidation of Hf and Al within the bond-coat. In addition, the oxygen barrier ability of the top-coat changed with its microstructure evolution.; A glass-based composite coating incorporating YSZ, corundum, and Ni3Al was prepared on IC10 superalloy with a sputtering Hf-modified Ni3Al bond-coat.
