Alumina(Al_2O_3) ceramic and poly-ether-ether-ketone(PEEK) composite coating was fabricated via plasma-spraying of Al_2O_3-coated PEEK composite powder. The structures of the composite powder and coating were analyzed by scanning electron microscopy. The wear and corrosion resistance of Al_2O_3 ceramic coating with PEEK were examined. The presence of PEEK in Al_2O_3 ceramic coating has a lubrication effect. The friction coefficient of the composite ceramic coating decreases, and the friction behavior is mor...
