Introduction of aluminum coating magnet for Motor Actuator Sensor
From the perspective of anti-corrosion and mechanical strength, the aluminum coating is an ideal choice for NdFeB magnet. The superiorities of aluminum coating includes:

The potential difference between aluminum and NdFeB substrate is very low, and could not be formed electrochemical corrosion.
There is a corrosion resistance, homogenous and dense layer will be generated on the aluminum coating under the atmospheric environments.
Aluminum is the most abundant element in the earth’s crust.
The corrosion products of aluminum coating arenon-toxic.
The corrosion resistance, colour and abrasion of aluminum coating will be further enhanced by the subsequent anodizing and electrolytic colouring.

For NdFeB magnet, its aluminum plating process contains ion vapor deposition technology and ion liquid electrodeposit. In fact, the application of ion liquid electrodeposit in NdFeB industry is not yet implemented, and all of the aluminum coating magnet are manufactured by ion vapor deposition technology. Sintered Neodymium Multipole Orientation Ring Magnet 40UH
Background of ion vapor deposition (IVD) aluminum coating

The ion vapor deposition (IVD) aluminum coating was developed by Mcdonnell Douglas Corporation for Unites States Air Force. The original intention of the aluminum coating is to replace the historically cadmium coating in aerospace and commercial market.
