日本日产汽车公司研究成一种用激光束进行钢板表面处理的新方法,能使喷漆的汽车车体表面光泽度大大提高。此法所用的激光束可在轧制钢板表面刻出许多火山口状的微孔,每个微孔的直径和深度为几微米。这些微孔相距只有几十微米,在钢板表面形成一幅均匀的几何图形。用这种方法处理 Japan’s Nissan Motor Co., Ltd. has developed a laser beam for steel surface treatment of new methods, paint the car body surface gloss can greatly improve. The laser beam used in this method can be engraved on the surface of rolling steel plate a number of crater-like microporous, each microporous diameter and depth of a few microns. These micropores are only a few tens of microns apart, forming a uniform geometry on the steel surface. Use this method to deal with
