Background
The electric brush plating technology is especially suitable for repairing and remanufacturing worn, corroded and scratched parts of mechanical equipment, such as large equipment and weapon armor surfaces, due to the characteristics of convenient operation, low cost, good repairing effect and the like. Nano particles are added into the plating solution for nano composite brush plating, so that the hardness and wear resistance of the plating layer can be further improved, and better protection of a substrate can be realized.
For the nano composite brush plating technology, how to uniformly disperse nano particles in plating solution and plating layer is a key for improving the performance of the plating layer, and is also a difficult point.
