i基渗Mo涂层新工艺的性能研究

i substrate is coated with a new process of Mo permeating in the way of slurrying and powder packing at different temperature. The structures of coat and topographies of surface and cross section have been investigated. The distributions for Mo and Ti elements have been observed. The properties of high temperature oxidation resistance have been measured. The results show that the kind of composite material has a good potential for high temperature application.
