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.

  1. Salt spray test: 48Hrs;                 Steady temperature damp test: 240Hrs
  2. Excellent oil resistance and solvent resistance;
  3. Smooth surface.

Spray Coating

Spray the epoxy anti-corrosion paint to compression magnet's surface.

Apply to small sized work pieces, especially for arc-compression magnets.

  1. High-effeciency & Good consistency & High passing rate; 
  2. Salt spray test: 24Hrs;                   Steady temperature damp test: 240Hrs.

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.

  1. High-effeciency;
  2. Simple process;
  3. No dimension change.

Infiltration

Infiltrate anaerobic adhesive  into compression magnet's voids by negative pressure.

Apply to extreme environment, such as oil or solvent.

  1. Seal magnet's voids;
  2. Improve strength;
  3. Make it possible to work under oil or solvent for a long time.
