Technology Improvement and Parameter Optimization on the Electroplating Superhard Grinding Material

The superhard abrasive tools are usually made by the electroplating abrasive method. The electroplating quality has the directly effect on the life and the performance of the superhard abrasive tools. The electroplating technology is the najor factor which influences the electroplating quality. The plating pretreatment and plating nickel processes in the basic eleetroplating technology were improved in this paper. The deburring, the oil removing by electrochemistry, the anode dispose procedures and a set of new electroplating technology about incoming slot with electronics and impact current in the plating nickel process were brought forward in this paper and the experiment research was taken as well. The resnh of the experiment which used the new technology showed that the binding power on the plating tier was enhanced, the electroplating quality was advanced; secondly, the effects of the parameters such as the directions tot the electroplating solution, the current density, the temperature of the eleetroplating solution and PH values on the electroplating quality were studied in the experiment. Finally the optimization result was gained.
