Abstract The cyclic oxidation behavior of Al-Si coatings on the Ni-base superalloy DZ125 has been investigated,which has been corroded by ro om temperature corrosion.The results indicated that the room temperature corrosi on decreased the Al content,and increased the surface roughness of the coating.D uring the subsequent cyclic oxidation,the phase transformation of βNiAl t oγ′Ni3Al and the spallation of Al2O3 scale are accelerated.As a re sult,the oxidation resistance and lifetime of the coating are decreased.
