60号钢表面碳钨合金激光包覆的特性分析

Property analysis for carbon-tungsten alloys laser cladding treatment on No. 60 steel surface

本文叙述了用一台高功率二氧化碳激光器在60号钢表面所作的碳钨合金包覆实验。实验结果表明在低质钢材表面包覆一层碳钨合金层大大地提高了工件表面的耐磨性能;包层厚度与激光扫描速度的平方成反比。

This article presents our experimental procedure of carbon-tungsten alloys cladding treatment on No. 60 steel surf ace by means of a high power CW CO2 laser. The experimental results indicate that a carbon-tunsten alloy cladding on a poor quality steel surface greatly improves its mechanical properties, the cladding thickness are inversely propotional to the square of laser scanning speeds.
