Abstract

ABSTRACT Traditional Si bond coats limit the increase of thrust‐to‐weight ratio in aero‐engines due to insufficient temperature resistance; hence, it is extremely urgent to develop new bond coats capable of withstanding higher temperatures (>1350°C). Herein, we select HfSiO 4 as a novel bond coat material and investigate the effects of atmospheric plasma spraying (APS) parameters and annealing conditions on the coatings. The as‐sprayed HfSiO 4 coatings are relatively dense, with a porosity
