用5 kW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2～3.5 mm、表面平整光滑和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组织及组织探制方法。

This paper investigates laser cladding NiCrFeBSi alloy on valve parts of 1Cr18Ni9Ti and Cr18Ni12Mo3Ti base metal with 5 kW transverse flow CW CO2 laser. A 2-3.5 mm thick cladding layer with smooth surface and fine microstructure is made. Based on the laser cladding experiment, the solidification microstructure control during rapid s...
