摘要
用 5 k W横流 CW CO2 激光器在 1Cr18Ni9Ti与 Cr18Ni12 Mo3Ti阀门零件上熔覆 Ni Cr Fe BSi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 。
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 solidification is analyzed and discussed.
