抄録
The gas tunnel plasma spraying method was employed to deposit HA/ZrO₂ composite coatings on SUS 304 substrate in an atmospheric chamber. The design of the plasma torch allows for the external and internal feeding of the sprayed powder. Pure HA powder was fed externally and ZrO₂ powder was fed internally. The feeding rate was controlled to deposit HA/ZrO₂ coatings with different zirconia contents. Two sprayed coatings with different zirconia contents were obtained. The influence of ZrO₂ and its volume fraction on the microstructure and mechanical properties of HA/ZrO₂ composite coatings was investigated. A comparison between the microstructure and mechanical properties of pure HA and HA/ZrO₂ composite coatings was made. Scanning electron micrographs of the coatings cross-sections showed good adhesion between the coatings and the substrate and also the dense structure of the coatings. The presence of ZrO₂ improved the hardness and abrasive wear resistance of the composite coatings compared with the pure HA coatings.
