The current application status and related challenges of neodymium iron boron magnets in the medical field
The magnets used in the body far exceed the requirements of "conventional" magnet applications, and the coatings on medical magnets in contact are biocompatible. The approved coatings for magnets include gold, Paliling, titanium, or rhodium. The correct coating helps improve corrosion resistance to certain chemicals and is also safe for internal use. The polyethylene terephthalate on magnets has long been associated with medical and technological applications, providing a corrosion-resistant and durable coating that can be used for Paliling C, D, and N.Magnets may experience scratches and debris in the coating during impact, impact, or grinding of other parts, leading to oxidation. In some applications, doubling the coating thickness may be helpful, but tolerances need to be checked to ensure that additional thickness can be used. Gold is an FDA approved medical coating for use in the body. It has a nickel copper nickel base coating, with a standard gold plating thickness of 0.3-0.6 mi
