For the purpose of solving problems inherent to a white Al2O3 spray coating, i.e. drawbacks that the injury resistance, corrosion resistance, heat resistance, abrasion resistance and the like are poor and the light reflectance is high because the coating is porous and weak in the bonding force among particles, there are proposed a spray coating member having excellent injury resistance and the like in which a surface of a substrate is covered with a colored Al2O3 spray coating of a luminosity lower than grayish white, achromatic or chromatic color.
