摘　　要：为了在黄铜基材上常温获得黑色膜层,研究了黄铜酸性氧化发黑工艺,着重对硒-铜-磷系发黑液进行研究。主要讨论了黄铜氧化发黑的前处理、溶液组分和着色时间等因素对着色膜层质量的影响。研究结果表明:溶液组分是影响着色膜颜色的主要因素,使用时要注意控制其含量;适量的添加剂可以提高着色膜质量。最终研制出一种常温KY型发黑液,与传统配方相比,该发黑剂具有发黑时间短、发黑膜耐磨且黑色纯正、光亮性好、生产成本低等优点,具有广阔的推广和应用前景。In order to obtain black films on brass at room temperature, the oxidative blackening process on brass in acid solution was studied. Emphasizing the study of blackening solution of Se-Cu-P system. Effect of pretreatment procedure, different solution components and coloring time and so on on quality of coloring film on brass were discussed. The results show that the solution component is the primary factor that affected the quality of coloring film, which should be carefully controlled. And the quality of coloring film can be improved by adding appropriate additives. Ultimately, a KY type brass blackening solution is prepared, compared with conventional formulations, the solution possesses more advantages, such as less blackening time, better wear resistance of the blackening film, pure andshiny black color, lower production cost, etc. It has a bright future in popularization and application.
