Abstract
Cold gas dynamic spray (CGDS) has been considered a potential technique to produce the metallic bond coat for TBC applications, because of its fast deposition rate and low deposition temperature. This paper presents the influence of spray processes for bond coat, including air plasma spray, high velocity oxy-fuel, and in particular CGDS, on the oxidation performance of TBCs with a Co-32Ni-21Cr- 8Al-0.5Y (wt.%) bond coat. Oxidation behaviour of the TBCs was evaluated by examining the coating microstructural evolution, TGO growth behaviour, and crack propagation during thermal exposure at 1050°C. The relationship between the TGO growth and crack propagation will be discussed.
