Abstract
A first material with a known maximum temperature of operation is coated with a second material on at Least one surface of the first material. The coating has a melting temperature that is greater than the maximum temperature of operation of the first material. The coating is heated to its melting temperature until the coating flows into any cracks in the first material's surface.
