前言激光表面处理工艺在表面强化诸方法中显示出突出的特点.我们对渗碳或渗碳、渗硼的低碳合金钢进行了多次激光相变硬化和激光表面熔化处理试验,并研究其成分、组织与耐磨性的变化.
Preface The laser surface treatment process shows outstanding features in various methods of surface strengthening.We conducted several laser phase-change hardening and laser surface melting tests on carburized or carburized, boron-infused low-carbon alloy steels and studied their Changes in composition, texture and wear resistance.
