Cathodic protection measures to ensure the wheel surface micro-abrasive group

Specifically includes the current types of different growth rate of the coating, results in a current density range of the coating growth rate calculation parameters, and according to the method Hull cell test dispersion bath and a suitable current density range, and the use of cathodic protection measures to ensure micro abrasive wheel  abrasive grinding  of the group, and the ring wheel plating jig improved, reducing the difficulty of the sand. Improve the abrasive wheel arrangement controllable  polycrystalline diamond . Through the above process improvement and optimization measures, to create a highly controllable bare grain, slightly abrasive grit good group of high-controllable sample wheel arrangement.
