摘要：
Alumincoating was prepared on a Ni-Cr-W-Al nickel-base superalloy by pack cementation, the effects of Al content and aluminizing temperature on coating formation were investigated. Coating microstructures were investigated using optical and scanning electron microscopes, EDS and X-ray diffraction (XRD) techniques. The results showed that the coatings prepared at 800 degrees C in the powders with 15%, 30% and 99% Al were different. NiAl3 coating was obtained in the conditions of aluminizing temperature of 700 degrees C, 750 degrees C, 850 degrees C and of Al content of 99%.
