Al-Si확산코팅에 따른 Ni기 초합금의 미세조직과 부식특성
Microstructure and Corrosion Characteristics of Al-Si Diffusion Coated Ni Base Super alloy
초록
The microstructure and corrosion properties of Al-Si diffusion coated PWA1426 alloy have been investigated. Experimental variables are included temperatures of heat-treatment and coating thickness. The microstructure of coated layer and corrosion properties were analysed by SEM, EDS and hot corrosion test. Two major processes have been found to contribute to microstructural changes in the coating. These are, firstly, the transformation of the NiAl to other
