AI Technical Summary
In the existing sintered NdFeB magnet barrel plating process, the steel balls used for plating consume a significant amount of plating metal, resulting in high production costs, unstable plating quality, and frequent replacement of consumables that affect production continuity.
Modified coated steel balls are used, including a steel ball substrate and an insulating ceramic layer covering the outer surface. The insulating ceramic layer blocks the electrodeposition reaction, reduces the consumption of coating metal, and maintains optimized conductivity and buffering function.
It significantly reduces the ineffective loss of coating metal, lowers production costs, improves coating quality stability and production efficiency, extends the service life of consumables, and maintains the stability and continuity of the process.
