| Abstract: |
| 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. |
