Anti corrosion method of Nd-Fe-B
Corrosion is widely used in many industries, and naturally it is no exception in the industry, because neodymium iron boron is easy to be corroded. Therefore, most finished products need electroplating or painting. Conventional surface treatment includes nickel plating (nickel copper nickel), zinc plating, aluminum plating, electrophoresis, etc. Phosphating can also be used if working in a closed environment.
Neodymium magnet products are widely used in packaging, toys, gifts and handicrafts, fitness magnetic control vehicles, motors, micro motors, computers, instruments, meters, motorcycles, cameras, clocks, sounds, household appliances, office automation, magnetic therapy and various fields of daily life.
Neodymium iron boron also belongs to powder metallurgy products, and its processing method is similar to samarium cobalt. At present, the high working temperature of Nd-Fe-B is about 180 ℃. In severe environmental applications, it is generally recommended not to exceed 140 degrees Celsius.
