| Abstract: | The orthogonal design approach is used to investigate the effects of the fluctuations of plasma spraying parameters on the tension bonding strength of Cr 2O 3 coating. The analysis of the experimental results shows that the arc current and the coating thickness have great effects on the tension bonding strength,and interactions exist between the arc current and the coating thickness. The tension bonding strength of Cr 2O 3 coating mainly depends on the porosity in ceramic layer. |
