Study on Application of Al-Si Coating Prepared by Fusing Slurry Process
Al-Si coating were prepared on nickel-base superalloy ЖС6У by molten slurry process.The effect of the slurry thickness on the coating depth and the substrate dimension,and the microstructure,microhardness and properties also was investigated and analyszed.The results show that the Al-Si coating possess advantages such as stable quality,compact microstructure,the good oxidation-resistance and good erosion-corrosion resistance,the coating bonds substrate with metallurgical bonding,and this coating can be widely used for many kinds of the parts which need good high-temperature corrosion resistance.
