US Patent:

51398761, Aug 18, 1992
Filed:

Mar 5, 1990
Appl. No.:

7/488984
Inventors:

Edgar E. Graham - Lyndhurst OH
James F. Makki - Oswego NY
Assignee:

Cleveland State University - Cleveland OH
International Classification:

B32B 3300
US Classification:

4284111
Abstract:

Means are disclosed to provide a ceramic article with a protective coating which resists mechanical wear at elevated temperatures up to 500. degree. C. and higher. The coating is applied by first chemically depositing activating metal ions on the uncoated ceramic surface and thereafter vapor depositing an adherent organic polymer lubrication film on the activated surface. Ceramic materials provided with such protective coating include silicon carbide, silicon nitride and vitreous silica.

Edgar E. Graham - Lyndhurst OH
James F. Makki - Naperville IL
Assignee:

Cleveland State University - Cleveland OH
International Classification:

C23C 1600
US Classification:

427255
Abstract:

A method is disclosed to provide a ceramic article with a protective coating which resists mechanical wear at elevated temperatures up to 500. degree. C. and higher. The coating is applied by first chemically depositing the oxide product layer of a transition metal element on the uncoated ceramic surface and thereafter vapor depositing an adherent organic polymer lubricating film on the oxide product layer. Ceramic materials provided with such protective coating include silicon carbide, silicon nitride and vitreous silica.
