Abstract
In order to advantageously solve problems such as lowering of the productivity, contamination of alloy coating due to the adoption of different metal, increase of the cost due to the adoption of different coating process, a coating of MCrAlX alloy is directly formed on a substrate surface of a member exposed to a high temperature at a thickness of 10.about.300 .mu.m through atmospheric plasma spraying process in air or flame spraying process (including low-velocity flame spraying process, high-velocity flame spraying process) and thereafter the same MCrAlX alloy is applied thereonto at a thickness of 100.about.800 .mu.m through low pressure plasma spraying process in a non-oxidizing atmosphere.
