用5kW横流CW CO_2激光器在1Cr18Ni9Ti与Cr18Ni12Mo3Ti阀门零件上熔覆NiCrFeBSi合金，得到了厚2～3.5mm，表面平整光滑，组织细密的合金熔覆层，并结合熔覆试验，分析探讨了激光熔覆层快速凝固过程中的凝固特征，凝固组织及组织控制方法。

This paper investigates laser cladding NiCrBSi Alloy on valve parts of 1Cr18Ni9Ti and Cr18Ni12Mo3Ti base metal with 5kW transvers flow CW CO 2 laser. A 2～3.5mm thick cladding layer with smooth surface and fine microstructure is made.Based on the laser cladding experiment, the solidification feature and solidification microstruture control during rapid so...
