Structural and surface analysis of plasma processed zirconia coatings

This paper reviews plasma deposition method of zirconia based ceramic coatings with regard to tribological applications. Subjects discussed include wear-resistant coatings from yttria-stabilized zirconia (YSZ) processed by plasma-spray technique on the stainless steel substrates employing non-equilibrium plasma spray technology at atmospheric pressure. The relation between the microstructure, surface texture and microhardness of the as-sprayed coatings was investigated.
