Optimization of preparation parameters for diamond nickel composite electrodes in electrical discharge machining
The influence of preparation parameters of chemical composite plating solution on the preparation of composite electrodes was studied,and the pretreatment steps of diamond micro powder were explained;The influence of the equivalent particle size of diamond micro powder on the composite electrode coating was analyzed,and the optimal coating diamond equivalent particle size was determined to be 10 pm;An experiment was conducted on the plating rate relationship of chemical composite plating under changes in plating solution temperature,and the optimal plating solution temperature was found to be 74-76 ℃;Through processing experiments on the prepared electrodes,it was found that the optimized composite electrode reduced electrode angle loss by 74.74％compared to ordinary copper electrodes;Parameter optimized composite electrodes reduced electrode angle loss by 57.29％compared to non optimized composite electrodes.
