Abstract

A duplex coating for substrates comprises an undercoat of tungsten carbide-cobalt having a strain-to-fracture of greater than 4.3x10<-><3> inch per inch and a top coat of a ceramic material such as alumina and in which the ratio of the thickness of the top coat to the undercoat is from 6:1 to 1:3.
