Magnetization of NdFeB bonded magnet
Surface treatment of NdFeB bonded magnet
Technology name | Introduction | Applicable scope | Feature |
Electrophoretic Coating | The most commonly used technique in industry. | Applicability to most compression magnets. |
|
Spray Coating | Spray the epoxy anti-corrosion paint to compression magnet's surface. | Apply to small sized work pieces, especially for arc-compression magnets. |
|
Anti-rust Oil Dipping | Anti-rust film can greatly improve compression magnet's anti-rust capability. | Especially suitable for small inner-diameter's compression magnet. |
|
Infiltration | Infiltrate anaerobic adhesive into compression magnet's voids by negative pressure. | Apply to extreme environment, such as oil or solvent. |
