These gold-coated wave springs require careful handling to preserve the 0.5–2 μm gold layer and maintain ≤1 mΩ contact resistance. The spring force must be kept within 5–30 N to avoid premature fatigue and ensure ≥10,000 cycle lifetime.

  • Coating Thickness Tolerance: Handle with non-abrasive tools to avoid scratching or wearing the gold coating.
  • Contact Resistance Limit: Ensure clean, oxide-free contact surfaces to achieve the specified ≤1 mΩ contact resistance.
  • Spring Force Range: Do not compress the spring beyond its free height to an extent that exceeds 30 N maximum force.
  • Fatigue Life Requirement: Limit repeated compression cycles to within the rated force range to achieve ≥10,000 cycle lifetime.

How does the gold coating thickness range of 0.5 to 2 μm affect contact resistance and mechanical fatigue life in these wave springs?

The gold coating is engineered to achieve a contact resistance ≤1 mΩ while maintaining a fatigue life ≥10,000 cycles across the entire thickness range. The 0.5–2 μm plating provides sufficient conductivity without compromising the spring's mechanical flexibility and durability.

What is the maximum voltage window these Au-coated wave springs can withstand without electrochemical degradation, and are they compatible with thin-electrode low-loading battery configurations?

The springs have been electrochemically verified to have no side reactions within -0.5 V to 5.0 V, making them suitable for most standard battery testing. Their large contact area and small footprint (15.4 × 1.1 mm) are specifically optimized for thin-electrode and low-loading battery assemblies requiring minimal contact resistance.

Are the ATOMFAIR Au-coated wave springs ready for immediate use in an argon glovebox without additional cleaning or preparation?

Yes, each pack undergoes 100% dimensional and coating inspection and is verified oil-free, burr-free, and impurity-free before shipment. They can be used directly from the packaging for battery assembly inside gloveboxes, eliminating pre-cleaning steps.

The ATOMFAIR® Au-Coated Wave Springs offer a gold-plated stainless steel design (0.5–2 μm coating, ≤1 mΩ contact resistance) for ultra-precision electrochemical testing, providing consistent spring force (5–30 N) and fatigue life ≥10,000 cycles; however, the single default size (15.4 × 1.1 mm) and fixed force range may require customization for non-standard battery assemblies.

Positive

  • Ultra-Low Contact Resistance: Gold coating (0.5–2 μm) achieves contact resistance ≤1 mΩ, minimizing electrical losses in EIS and micro-current measurements.
  • Broad Electrochemical Stability: Validated via constant potential polarization and cyclic voltammetry to remain inert from -0.5 V to 5.0 V, ensuring no interference with battery test results.

Trade-offs

  • Fixed Force Range Only: Spring force is limited to 5–30 N from a single spring geometry; applications requiring forces outside this range cannot be directly accommodated.
  • Single Default Dimension: Standard size (15.4 × 1.1 mm) is non-adjustable; alternative sizes require custom orders, adding lead time and minimum quantity constraints.
