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.
Now MPCO Magnetics can supply TiN coated Neodymium magnet disks, bars and blocks.

Neodymium is a rare earth type of permanent magnet made from an alloy of neodymium, iron, and boron. Neo magnets are currently the strongest permanent magnets known. It is also one of the most abundant of the rare earth elements. Highly Efficient Motors Magnet for AC Submersible Hydraulic
These magnets are cheaper, lighter, and stronger than samarium-cobalt magnets. However, neodymium magnets lose their magnetism at high temperatures. Samarium-cobalt magnets do not.
Neo tends to be vulnerable to corrosion similar to rusting, causing the magnet to weaken and eventually break down into a powder. This problem is solved by applying a protective coating. Nickel plating or nickel/copper/nickel plating is used as a standard method, although many other protective coatings are also in use.
It is not recommended to use the magnet without a protective layer. The application of the magnet will affect the choice of coating. For example gold plating is ideal for many medical applications, rubber coating provides additional friction, rubber coated zinc plating is used in marine environments, etc. AZ Industries is a bulk & wholesale supplier of all types of neodymium magnets.
