OXIDATION-RESISTANT FILM AND ITS DEPOSITION METHOD, THERMAL BARRIER COATING, HEAT-RESISTANT MEMBER, AND GAS TURBINE

摘要

PROBLEM TO BE SOLVED: To provide an oxidation-resistant film compatibly having the oxidation resistance, the ductility and the toughness during the long time service, and its deposition method.;SOLUTION: A MCrAlY layer mainly containing a MCrAlY alloy (where, M denotes at least one kind of element out of Co and Ni) is deposited by thermal spraying or vapor deposition on a base material having a heat-resistant metal. Then, aluminum is diffused in a part of the MCrAlY layer in the thickness direction from a surface opposite to the base material in the MCrAlY layer.;COPYRIGHT: (C)2008,JPO&INPIT
