Method for reducing laser drilling surface splashes

一种减少激光打孔表面飞溅物的方法

Abstract

The invention provides a method for reducing laser drilling surface splashes. The method includes the following steps that 1, a test sample is polished, and then the test sample is ultrasonically cleaned and dried for standby application; 2, the upper surface of the test sample is evenly coated with an organic coating which is a mixture of paraffin and stearic acid; 3, a millisecond pulse Nd:YAG laser is used for carrying out laser drilling on the processed test sample; and 4, the surface organic coating is removed, and the effect is observed. According to the method, the material of the organic coating is melted at a certain temperature and can flow to places not covered with the coating in the drilling process, and therefore a processed face can be effectively protected against oxidation, and the whole drilling process is well protected. The material of the adopted coating is cheap and easy to obtain, and good economic benefits are achieved. Through the adopted coating material, coating is convenient, adopted equipment is simple, the coating is easy to remove after drilling without complex aftertreatment, and operation is quite convenient.
本发明提供了一种减少激光打孔表面飞溅物的方法,包括如下步骤:步骤1、首先对试样进行抛光,然后将试样进行超声清洗,干燥备用;步骤2、将有机涂层均匀涂于试样上表面,有机涂层为石蜡和硬脂酸混合物;步骤3、用毫秒脉冲Nd:YAG激光对处理好的试样进行激光打孔;步骤4、去除表面有机物涂层,观察效果。本发明中,有机涂层材料在一定温度下会熔化,在打孔过程中会流向膜层覆盖不到的地方,能够有效保护加工面不被氧化,对整个打孔过程具有很好的保护作用。使用的膜层材料廉价易得,具有较好的经济效益。本发明使用的膜层材料镀膜方便,使用设备简单,打孔后膜层的去除简单,不需要复杂的后处理,操作非常方便。
