Y2O3 THERMAL SPRAYED FILM COATED MEMBER AND PROCESS FOR PRODUCING THE SAME |
摘要 |
<p>A member is obtained by forming a Y 2 O 3 black spray coating on a surface of a substrate or covering the surface of the substrate with a Y 2 O 3 black spray coating through an undercoat or a middle layer. This coating has good heat characteristics and is good in the resistance to damaging through a high hardness. The Y 2 O 3 black spray coating is produced by subjecting white Y 2 O 3 powdery material to a plasma spraying in an inert gas atmosphere containing substantially no oxygen or by forming a Y 2 O 3 white spray coating and then irradiating an electron beam or a laser beam to this coating to melt at least a part of the white coating under heating to thereby smoothen denseness and blacken the surface of the coating.</p> |
