ABSTRACT:
Ceramic substrates, e.g. of silicon carbide or silicon nitride are protected against mechanical surface wear at high temperatures by an arc coating with a refractory metal followed by coating with another metal and then with a wear-reducing high density layer, e.g. of a metal oxide, nitride or carbide.
