Abstract

Three kinds of plasma spray coatings of FeAl,FeCrAl and FeCrAlRE were prepared by using instantaneous high-energy shock wave effect produced by electro-thermal explosion of metal conductor alloy foil of FeAl base.SEM showed that spray coatings possessed nano-structure and micro-structure,and the coating formed a metallurgical binding layer with its base metal,and there was an evident buffer layer between coating and its base metal.Corrosion changing rule of these three plasma spray coatings was gained after anti-corrosion testes under the conditions of high temperature oxidation,and good electro-thermal explosion FeCrAlRE plasma spray coating with high temperature oxidation resistance was selected.
- Electro-thermal explosion,
- Plasma spray coating,
- FeCrAlRE,
- High temperature oxidation resistance
