摘要
为了研究各种激光工艺参数对彩色打标效果的影响及其相互关系,通过计算获得了纳秒激光脉冲在不锈钢表面打标产生的温度场的解析结果,模拟了一系列激光脉冲由点打标成线、由线连成面的热作用过程。通过打标实验验证了对不锈钢激光彩色打标进行热分析的合理性。研究表明:激光工艺参数是通过热作用来影响打标效果,不同参数组合的激光结果能产生相同的颜色。同时发现,不同工艺参数的变化改变不同形式的热输入,产生的热影响会有一定的区别,一些彩色效果只能在特定的工艺参数组合的激光作用下才能产生。
In order to study the influence of laser processing parameters on the resulting color and a possible connection of laser parameters, the heating process of the stainless steel in laser marking are simulated based on the analytical results of temperature fields generated by nanosecond laser pulse marking on the surface of stainless steel. Experimental results indicate the reasonability of the heat analysis in this study. It is found that the influence of laser process parameters on the resulting color are based on heat treatment, so the same color can be produced by different sets of parameters. Besides, different types of heat input are changed by various laser parameters, which produce different heat treatments. Accordingly, some colors can be marked only by specific sets of laser parameters.
