How to Avoid Pot Magnet Corrosion?

Time:2023-2-10 Edit:WZ Magnetics

Pot Magnet with coatings provide a range of benefits to magnets, including enhanced corrosion resistance. There are different ways to avoid corrosion in Pot magnets and to keep them working optimally. There are various types of coatings available for pot magnets such as electroplating ,electrophoresis and rubber coating. More important is to have proper storage and maintenance when using pot magnets.

Different types of magnet coatings can be used to achieve different outcomes, depending on the desired application. For instance, rare earth magnets are often coated with nickel or zinc for increased corrosion resistance and salt spray resistance.

Similarly, magnets used in medical applications often require a coating that is resistant to heat or radiation.

Pot magnets are a type of permanent magnet that is commonly used in many industrial and commercial applications. However, if not taken care of properly, pot magnets can corrode and lose their magnetic properties.

The Rare earth magnets are widely used in pot magnets due to their high magnetic field strength and durability. By electroplating, electrophoresis, and rubber coating these rare earth magnets, the performance of pot magnets can be further enhanced by providing additional protection from corrosion and improving their magnetic holding force.


(1) Electroplating

Electroplating is the process of coating a metal surface with another metal or alloy by electrolysis. This process uses electrolysis to attach a layer of metal film to the surface of metal or other materials, so as to prevent the permanent magnet from oxidation (such as corrosion), improve its wear resistance, conductivity, reflectivity, corrosion resistance and enhance the aesthetic effect.

(2) Electrophoresis

Electrophoresis is the process of moving charged particles towards opposite electrodes under the action of an electric field. Electrophoresis is the separation of charged particles in an electric field at different speeds. This is one of the technologies widely used in anti-corrosion surface treatment of China neodymium pot magnet . The electrophoretic coating can be well attached to the surface of the porous magnet, and it is resistant to salt spray, acid and alkali corrosion.

(3) Rubber Coating

Rubber coating is an effective way to prevent pot magnets from corrosion. It provides a protective layer on the surface of the magnet, which can make it more resistant to oxidation or other forms of corrosion. Magnet with rubber coating also increases the durability of the magnet as it is scratch and waterproof. This allows for a longer life span for pot magnets in comparison to those without rubber coating.

In addition, rubber coating can also improve the appearance of pot magnets, making them look more aesthetically pleasing. This makes them suitable for use in various applications where aesthetics are important. With its corrosion resistance, no scratch and waterproof properties, rubber coating provides an ideal solution to protect pot magnets from environmental damage and extend their life span.
