英文摘要The formation of diffusion barrier on the ni-based superalloy substrate by low-pressure pre-oxidation is studied in this paper. the pre-oxidation was carried out by heating the substrate under a low-oxygen partial pressure with electron beam of the electron beam physical vapor deposition (eb-pvd) facility. the effect of diffusion barrier was investigated by both isothermal and cyclic oxidations at 1373 k, and the oxidation-kinetic curves were then obtained. the diffusion barrier mainly contains nio, alpha,beta-al2o3 and cr2o3, and has a thickness of 185-225 nm. the investigation indicates that the barrier could partially inhibit the interdiffusion of elements of the superalloy substrate and then improve the oxidation-resistance performance of thermal barrier coatings (tbcs) to some extent. however, the difference of thermal cycling lifetime between tbcs samples with and without diffusion barrier is not extremely visible.
