Abstract
For the purpose of solving problems inherent to a plasma spray coating of white base Al2O3—Y2O3 composite oxide, i.e. drawbacks that the corrosion resistance, heat resistance and abrasion resistance are poor and the light reflectance is high because the coating is porous and weak in the bonding force among particles, a spray coating member having an excellent heat emission property and the like is proposed wherein a surface of a substrate is covered with a spray coating of a colored composite oxide made of a low luminosity, achromatic or chromatic Al2O3—Y2O3.
