Improving wear resistance of plasma-sprayed calcia and magnesia-stabilized zirconia mixed coating: roles of phase stability and microstructure.

The phase stability and microstructure of ZrO-5CaO and ZrO-24MgO mixed coating (wt%) by air plasma spraying on 304 stainless steel substrates were investigated. A Ni-5Al (wt%) metallic bond coating was firstly sprayed between the substrate and the ceramic top layer. The results were compared with the individual coatings of ZrO-5CaO and ZrO-24MgO for a better understanding of the correlation between their microstructures and mechanical properties.
