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.about.500 .mu.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.about.800 .mu.m through a low pressure plasma spraying process in a non-oxidizing atmosphere to form a composite sprayed coating.
