Ion Vapor Deposition (IVD) Aluminum Coating Neodymium Magnet, Custom Aluminium Magnets, Aluminum Coated NdFeB Permanent Magnet, IVD Alu Plated Rare Earth Rod Magnet China Supplier
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.
