Abstract

The influence of plasma spraying currents and gun transverse speeds on the characteristics of composite coatings was investigated. The porous microstructure and low bonding strength of the composite coatings were due to lower spraying current and faster gun transverse speed. In hydroxyapatite (HA)/Y-ZrO₂ coatings, the amount of HA decomposition increased with increasing spraying currents. Y-ZrO₂ reacted with CaO in HA forming CaZrO₃ and causing an increase in the decomposition of CaO-poor HA.
