| Abstract: | WT5BZ]The jet property of high efficiency plasma jet (HEPJet) system,and the characteristics such as bond strength, Vickers hardness, porosity and microstructure of the Al_2O_3 coatings prepared by this system were studied.Comparison of Al_2O_3 coatings was made between conventional plasma spray system and HEPJet system. The results showed that the characteristics of the Al_2O_3 coatings prepared by the HEPJet system were superior to those sprayed by the latter system. |
