Surface treatmen

For iron component (about 66%), it is easy disadvantages oxidizing power is strong rust there often (neodymium magnet) Nd-Fe-B sintered magnet. Surface treatment that a mandatory essential to prevent it, there is a method using various materials in it. To determine the material of plating depending on the environment used is neodymium.
