摘要：The purpose was to clarify the relationship between the main process parameters of micro-plasma cladding and the comprehensive quality(geometry,microstructure and wear rate of cladding track).Self-fluxing ferrous alloy powders were fabricated on Q235 *** on the uniform design,the distribution of the experimental samples was designed reasonably in the sample space,which greatly improved efficiency and reduced *** a series of microstructural characterization,there was no difference in the phase composition of all samples,but the average grain size had a significant difference,which resulted in the change of wear *** the relationship among micro-hardness,average grain size and wear rate of the track had also been ***,an optimization model was established and the optimal process parameters were obtained with excellent wear rate under the geometric *** correctness of optimization model was verified by experiments.
