Experimental Study on Single-layer Laser Cladding Feeding by Micro/nano Composite Powders

摘要：

　　Aimed at the lack of the cladding materials such as micro or nano powder,the micro/nano composite powders prepared for experiment are feed directly,the key process parameters on the quality of the surface quality and microstructure analysis of the single-layer of laser cladding are studied in detail.Compared to the ordinary laser micro-cladding layer feeding by the micro powder,the cladding layer is more refined,which has more good mechanical properties.The results showed that: using reasonable parameters,the microstructure and macro-morphology of cladding layer with micro-nano composite powders feed directly are better than of micron powders.
