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.
Monte-Bianco Magnets Co., Ltd. is a high-tech enterprise specializing in the research and development, production of sintered neodymium iron boron and other permanent magnet materials.
The company has a R&D and production team with mature technology and excellent style, which has an annual production line of 1500 tons of sintered Nd-Fe-B, complete detection and analysis instruments and equipment, perfect quality and environmental management systems such as ISO9001, ITAF16949 and ISO18000, and constantly improving and expanding sales and service network. It independently develops and produces various rare earth permanent magnetic materials such as sintered Nd-Fe-B.
