Dysprosium and Terbium Infiltration Technology

Monte-Bianco Magnets Co., Ltd. has conducted in-depth technical research and development cooperation with Ningbo Engineering University and Hunan University on the infiltration of dysprosium and terbium. And achieved phased results.

Dysprosium (terbium) grain boundary diffusion technology, or Dysprosium diffusion technology, is the application of Magnetron sputtering, vacuum evaporation, electrolytic deposition, electrophoretic deposition, surface coating and other methods to form a metal or alloy coating or coating with high Dy heavy rare earth element content on the surface of sintered Nd-Fe-B magnets with a thickness of about 1~9 mm, and then carry out appropriate heat treatment and low temperature tempering treatment, The intrinsic coercivity of the magnet can be significantly increased, while its residual magnetism does not significantly decrease or only slightly decreases.
