| 摘 要： | 研究了以Met和DMDMH为配位剂的无氰镀银工艺,通过探讨镀液组成及工艺条件对镀层外观质量的影响,确定了最佳电镀工艺。测试了镀液的阴极电流效率、分散能力、覆盖能力,以及银镀层的微观形貌和结合强度等。测试结果表明,该无氰镀银工艺基本达到了氰化物镀银工艺的相关指标,有望成为氰化物镀银的替代工艺。

| Abstract: | A cyanide-free silver electroplating process with Met and DMDMH as coordination agents was studied.The influences of bath composition and operation conditions of the process on the appearance of silver coatings were investigated,and on this basis the optimal electroplating process was defined.It has been found by examinations of cathode current efficiency,throwing power,covering power of the bath and adhesion of the silver films that this process is the same as and even better in some aspects than cyanide p... |
