Abstract
Corrosion-resistant, oxidation-resistant, and/or wear-resistant coatings are made of ternary ceramic compounds of the general formula (I): EQU M.sub.2 X.sub.1 Z.sub.1 (I) wherein M is at least one transition metal, X is an element selected from the group consisting of Si, Al, Ge, Pb, Sn, Ga, P, S, In, As, Tl and Cd, and Z is a non-metal selected from the group consisting of carbon and nitrogen; and/or compounds of the general formula (II): EQU M.sub.3 X.sub.1 Z.sub.2 (II) wherein M is at least one transition metal, X is at least one of Al, Ge, and Si, and Z is at least one of carbon and nitrogen. Such coatings may be applied by a thermal spraying process.
