Surface Treatment & Coating Technology
To ensure excellent corrosion resistance, surface integrity, and long-term magnetic stability of this thermally stable high-strength bar magnet, a comprehensive surface treatment and finishing process is applied as follows:
Edge Reinforcement
Critical joint and edge areas are reinforced using nickel-based laser cladding technology. This process forms a dense metallurgical bond that effectively minimizes electrochemical corrosion and enhances structural durability.
Edge Rounding Treatment
Precision edge rounding is applied to reduce local magnetic field distortion, improve coating uniformity, and lower the risk of chipping during handling and assembly.
Standard Surface Coating
The magnet is protected by a multi-layer Ni–Cu–Ni coating system, offering reliable corrosion protection and consistent surface quality. Coating specifications can be customized to meet specific application requirements.

FAQ
Q1 Why is magnetization orientation critical for sensor accuracy?
Answer:Sensor output depends on predictable field geometry. Small orientation errors can distort signal shape, causing calibration drift or measurement noise.
Q2. How do repeated thermal cycles affect NdFeB magnets?
Answer:Thermal cycling can gradually reduce coercivity margin and stress coatings. Proper grade selection and testing ensure stability under cyclic conditions.
Q3. When should system-level magnetic simulation be used?
Answer:Simulation is recommended when performance margins are tight, multi-pole fields are involved, or interactions with steel components significantly influence flux distribution
