A coated metal substrate with a ceramic composition and method which involves applying several layers of the following materials: a. stainless steel b. thermal shock resistant ceramic coating; and c. abrasion resistant ceramic material. Each layer of each material is applied by flame spray means to the metallic substrate which is at a temperature above 250 DEG F. but below 500 DEG F., which is then cooled to a temperature below 250 DEG F. before applying the next layer. Zirconium oxide is a preferred thermal shock resistant ceramic coating and aluminum oxide is the preferred abrasion resistant ceramic material.
