Abstract

In a method for forming a ceramic coating film with improved plasma resistance, ceramic powder is dispersed so that the particles of ceramic powder have 0.1-1.0um diameter. The dispersed ceramic powder is sprayed onto the surface to be coated at high speed and the ceramic powder is thus deposited onto the surface. As a result, a ceramic coating film with about 0.1-1% porosity is formed on the surface.
