Coatings which have been used successfully include, E-coat (a liquid dip epoxy coating), dry electrostatic spray epoxy, nickel plating and combinations of these coatings. Changes in composition and processing over the past several years have resulted in significant improvements in corrosion resistance and high temperature performance.
Magnetic properties
Neodymium magnets have higher remanence, much higher coercivity and energy product, but often lower Curie temperature than other types. Neodymium is alloyed with Terbium and Dysprosium in order to preserve its magnetic properties at high temperatures.
1.The magnets must be slid off/on. Neodymium magnets are brittle and prone to chipping and cracking. They do not take kindly to machining.
