摘　　要：本文首先介绍了黑色薄膜的制作;其次讨论了两种吸收剂黑色薄膜和黑漆涂层对激光辐射能量吸收的影响,主要包括两个方面,薄膜厚度对热量吸收的影响和碳黑的含量对热量吸收的影响,研究发现吸收薄膜厚度≥0.09mm就能吸收所有的红外辐射能量;碳黑含量为0.07%是吸收能量的理想值;最后,对使用两种吸收剂的焊接样品质量进行对比,发现黑漆涂层的焊接质量远比黑色薄膜的要好。First of all, the making of black film is introduced; secondly the influence of two kinds of additive： black film and coating on heat absorption is investigated, which includes influence of film thickness and carbon content on heat absorption, finding that all radiation heat will be absorbed when film thickness：≥0.09mm, and that carbon content 0.07 % is the optimized value; at the end of the paper, the welding quality of samples with black film and coating is compared ,and experimental resuhs indicate that coating is much better than black film.
