Abstract:
This invention is to provide a fluoride spray coating covered member having excellent resistance to halogen corrosion and resistance to plasma erosion and displaying identification symbols such as letters, numeric characters, graphic, pattern, firm name, serial number and so on. In the invention, one or more implanting gases selected from fluorine-containing gas, oxygen gas and inert gas are ion-implanted onto a white fluoride spray coating formed on a surface of a substrate, whereby at least a part of the surface of the white fluoride spray coating is changed into a black color to form a black ion-implanted layer.
