Single-phase Si-modified β-NiAl coating formed by irradiation of Al-Si plasma: Microstructure and oxidation behavior
Source abstract
Abstract
A single-phase Si-modified β-NiAl coating was formed by direct irradiation of Al-Si plasma in vacuum, which is distinctively different from that of the conventional AlSi slurry-diffusion process that normally generates silicides precipitation. A large amount of nanocavities was observed in the plasma-irradiated coating, which might relate to the formation of the single phase. Oxidation of the two coatings at 1000 ℃ shows that the single-phase coating formed an intact and uniform alumina scale whereas the conventional one formed a void-containing and rumpling scale, indicating the uniquely beneficial effects by forming the single-phase Si-modified β-NiAl coating.
