Ceramic Coating Method

Abstract

A method of coating a ceramic and bonding ceramic onto a substrate for practical uses over 630 degrees C. includes forming a brazed bonding layer at a contact area between the ceramic and the substrate by fluidic reaction and causing the bonding layer to wet both the ceramic and substrate with a wetting angle of 0-5 degrees to thereby coat and bond the ceramic onto bond the substrate over the entire contact area with a continuous, essentially 100% dense bonding layer. The bonding layer is so free of bonding defects that the resulting bonded product can withstand repeated thermal shocks by quenching 0 degrees ice water from a temperature in the range of 630-980 degrees C.
