Beschichtungsverfahren zum Schutz von Keramikgegenständen gegen mechanische und thermische Störeinflüsse und schutzbeschichteter Keramikgegenstand

摘要

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.
