A microstructured or nanostructured multi-component ceramic comprises (a) a major ceramic phase comprising a ceramic oxide composite; (b) a ceramic oxide additive; and (c) a rare earth ceramic oxide additive, wherein the total of the additives (b) and (c) comprise from about 0.1 weight percent to less than 50 weight percent based on the total weight the multi-component ceramic composite. In another embodiment, a microstructured or nanostructured multi-component ceramic comprises (a) a major ceramic oxide phase comprising a ceramic oxide composite; and either (b) a ceramic oxide additive or (c) a rare earth ceramic oxide additive, wherein amount of the additive (b) or (c) comprises from about 0.1 weight percent to less than 50 weight percent based on the total weight the multi-component ceramic composite. Such ceramics are useful as bulk materials or as feedstocks for thermal spray.

Multi-component ceramic compositions and method of manufacture thereof

A method for the deposition of solid lubricant coatings onto a substrate, comprising thermally spraying a powder comprising agglomerates of a solid lubricant coated with sulfur. Preferably, the solid lubricant is a sulfide. The coatings find particular utility on rollers used in the manufacture of steel.
