Tribological Performance of Ultra-hard Ceramic Composite Coatings Obtained through the Microplasma Oxidation

摘要：

　　Ceramic oxidation coating of approximately 60 μm thick was prepared on a Ly12 alloy substrate by micro-plasma oxidation in an alkali-silicate electrolytic solution.Coating thickness was measured during coating formation.The influence of current density,electrolyte temperature and inter-electrode distance on coating kinetics was investigated.Microstructure and phase compositions were analyzed.The micro-hardness of the coating was also measured.The tribological performance of the coatings was evaluated using a dry sand abrasion test.In addition,the results are compared to detonationsprayed alumina coating.
