摘要
主要对一种典型的模具钢-Cr12的激光切割试件进行了切缝宽度、表面质量、显微硬度、显微组织等方面的研究．并在此基础上对激光切割45钢、Q235－A钢、陶瓷表面质量进行了对比．
A laser cutting sample of a typical die steel -Cr12 is studied on its surface quality, microhardness and microstructure. A comparison is made of the surface quality of the samples made of 45steel,Q235-A steel and ceramic.
