Titanium Nitride Coated Neodymium Magnets

Titanium Nitride (TiN) has good chemical stability and corrosion resistance.

Bare Neodymium magnets implanted in the human body is extremely easy to corrosion. The corrosion not only affects the Neodymium magnets’ performance, but also leads to the release of potentially harmful substances due to Neodymium magnets chemical compositions.

Titanium Nitride coating is nonmetallic oxide ceramics material in golden yellow color. It is pretty hard with Young’s modulus between 350 and 600 GPa and so that has high wear resistance. TiN coated Neodymium magnet material has the property of corrosion resistance. More important, Titanium Nitride exhibits significantly lower bio reactivity than any other materials currently used as coating materials for Neodymium magnet products, such as Ni-Cu-Ni. TiN coated Neodymium magnets are used in orthopedic implants due to its high corrosion resistance and non-reactivity in human body.

Titanium Nitride (TiN) is a FDA approved medical coating for in-body use. Titanium Nitride is a hard coating that has a very strong bond to the magnet. TiN is resilient to most chemicals and environmentally friendly. This special coating works to protect from humidity and fluids. The finished color is a metallic gold with a smooth surface. Typically the thickness is around 2-3 microns. The maximum operating temp is approximately 500o C.
