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 containing an oxide such as CoO, NiO or the like is directly formed at a thickness of 10˜500 &mgr;m through a low pressure plasma spraying process containing substantially no oxide and thereafter the same MCrAlX alloy xontaining no oxide is applied thereonto at a thickness of 100˜800 &mgr;m through a low pressure plasma spraying process in a non-oxidizing atmosphere to form a composite sprayed coating.

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.
