摘要	Ni-Cr-Al-P coatings were deposited on the Ni3Al-base superalloys IC-6 and K17 by are-ion plating. The results indicated that a small amount of substrate atoms, such as Co, Ti, Mo, etc., existed in the Ni-Cr-Al-Y coatings near the substrates, probably due to "sputter" and "antisputter." For the alloy K17, the impeding effect of Al was not obvious, because the temperatures of the substrate and the coating were high (420-480 degreesC) during the deposition process and interdiffusion was accelerated. However, for alloy IC-6 which contains Al, as well as a high concentration of Mo, the diffusion of Cr was impeded. Vacuum heat treatment at 1050 degreesC drastically increased diffusivities and the presence of Al and Mo was not enough to prevent some Cr diffusion. Thus, the coating became mor e uniform and close to the desired composition.
