PVD Coating for Magnets – A Modern Alternative to Traditional Plating
In the world of permanent magnets, protecting the magnetic material from corrosion, wear, and environmental damage is essential. Traditionally, Ni-plating or Ni-Cu-Ni plating has been the go-to solution for surface protection, especially for neodymium (NdFeB) magnets. However, a newer technology—PVD…
