| Abstract: | Owing to complicated shape of tooth gear surface,the power lines are unevenly distributed everywhere in DC silver plating,causing uneven coating thickness,which will affect gear engagement.A bidirectional pulse power supply was used to silver plating and the optimum technological parameters were selected based on the comparisons in coating appearance,thickness uniformity,etc.The results show that the coating has been much improved in appearance and thickness uniformity,and the bonding strength,purity as well as hydrogen brittleness of the coating are all up to the requirements of AMS 2412. |
