【Abstract】 The article focus on the analysis of relationship between the mechanical properties,tribological properties and microstructure of the WC-12 Co coating prepared by the supersonic equipment. Supersonic flame spraying is used to study the influence of process parameters on the microstructure and tribological properties of WC-12 Co coating. The frictional moment is studied by observing the coating,analyzing the microstructure and using the statistic tool based on neural network calculation;it is concluded that the supersonic flame spraying process parameters have great influence on the composition,hardness and porosity of the phase structure of WC-12 Co coating. The relationship between spraying process parameters and the coating quality could be predicted under steady state mechanism.更多还原
