Abstract
A ceramic, metal, or metal alloy surface is covered with lithium permangae which is then thermally decomposed to produce a corrosion resistant coating on the surface. This coating serves as a primer coating which is preferably covered with an overcoat of a sealing paint.
Claims12
A process for forming a corrosion-resistant metal oxide coating on a surface comprising:
- A. heating a diamond, ceramic, metal, or metal alloy surface to a temperature above 190.degree. C.;
- B. covering the heated surface with lithium permanganate powder;
- and
- C. allowing the lithium permanganate to decompose and form a metal oxide coating on the heated surface.
