ABSTRACT:
Cermet composition having high temperature oxidation resistance, high abrasion and corrosion resistances, and good thermal shock resistance, and particularly adapted for production of high temperature resistant cermet insulator bodies, comprising a sintered body of particles of stainless steel or molybdenum, in a ceramic phase comprised of a ceramic oxide, particularly a ceramic mixture of chromium oxide and aluminum oxide, and forming a coating of chromium oxide as an oxidation barrier around the metal particles, to provide oxidation resistance for the metal particles.
The cermet compositions are designed particularly to provide high temperature resistant refractory coatings on stainless steel or molybdenum substrates.
