Surface Treatment & Coating Technology
Coating Systems:
- Ni–Cu–Ni Plating: The most widely adopted coating, providing balanced corrosion protection, strong adhesion, and good wear resistance.
- Epoxy Coating: Offers superior resistance to moisture, salt spray, and chemical exposure, suitable for harsh environments.
- Zinc Plating: A cost-effective option for moderate corrosion protection in controlled environments.
- Parylene Coating: A conformal, pinhole-free polymer coating ideal for medical, vacuum, and cleanroom applications.
Advanced Edge Treatments:
For high-reliability applications, additional measures such as edge rounding and localized alloy reinforcement may be applied to reduce stress concentration and prevent localized corrosion initiation.
Quality Inspection of NdFeB Magnets
To ensure consistent performance and reliability, NdFeB magnets undergo comprehensive quality inspection at each critical stage:
Magnetic Property Testing
Measurement of Br, Hcj, Hcb, and BHmax to confirm compliance with specified grades.
Dimensional Inspection
Precision measurement of thickness, length, angle, and geometry to meet strict tolerance requirements.
Appearance & Surface Coating Check
Visual and coating inspections to detect cracks, chips, pinholes, or plating defects.
Magnetic Orientation Verification
Confirmation of magnetization direction and polarity accuracy.
Batch Consistency Control
Sampling tests to ensure uniform performance across production batches.

FAQ
Q1. What criteria define failure during thermal shock testing?
Failure is defined by excessive flux loss, visible cracking, coating delamination, or mechanical fracture after rapid temperature transitions.
Q2. How is compressive strength correlated with magnet geometry?
Compressive strength data is analyzed in relation to magnet shape, aspect ratio, and edge conditions to optimize design and reduce fracture risk.
Q3. How is long-term storage stability tested?
Magnets are stored under controlled temperature and humidity conditions for extended periods, with periodic magnetic and visual inspections to monitor degradation.
