Abstract
A ceramic coating method for coating a ceramic on a metallic substrate is disclosed where a ceramic material is coated on a surface of a metallic substrate by continuously changing the composition of a mixture of a ceramic material and a metal to form a ceramic coating film on a surface of the metallic substrate. A heat treatment then is effected to the ceramic coated metallic substrate so as to induce a residual stress due to compression on a surface of the ceramic coating film, thereby improving the durability of the ceramic coating film.
