| Abstract: | Concerning on surface worn typical vehicle-parts made of 18Cr2Ni4WA case-hardened steel,a remanufacturing process of laser cladding Fe90 alloy powders was investigated.To analyze the dilution,the SN ratio and variance analysis methods were adopted.It indicated that the significant factors to dilution ratio are laser power and powder feed rate,the quantified relation between the processing parameters and dilution ratio was obtained simultaneously.And the principle of high microhardness was analyzed with synt... |
