| Abstract: |
| In order to further increase the brightness of electroless silver plating and improve the performance of bath, the influence of a, a' -Bipyridyl and sodium thiosulfate on the face of coating was studied by Hull Trough test, surface morphology of coating with basic formula and optimizing formula ( including additives) was observed by metalloscope. The results show that using 2,2-Bipyridyl and sodium thiosulfate can increase brightness of coating, enlarge the scope of current density. |
