长期以来,人们广泛认为铜材能用激光进行加工.铜的高反射率和特高的导热率使之不易切割和焊接.意大利巴里市激光实验中心的几位研究人员已发现一种用2kWCO_2激光切割厚达4mm的铜板的办法.其法是对激光照射的材料部分进行氧化,形成氧化亚铜与氧化铜.平均切割速度为10mm/s,视铜的厚度而定.
It has long been widely believed that copper can be laser machined, copper’s high reflectivity and exceptionally high thermal conductivity make it difficult to cut and weld, and several researchers at the Barry Experimental Center in Bari, Italy, have found that using a 2kW CO2 laser The method of cutting a copper plate up to 4 mm in thickness is to oxidize part of the laser irradiated material to form cuprous oxide and cupric oxide with an average cutting speed of 10 mm / s depending on the thickness of the copper.
