Core Unique Characteristics
1. Controlled Micro-Porous Structure Uniform microscopic pore distribution creates a micro-rough active surface. These tiny voids provide mechanical interlocking sites for the subsequent bright nickel layer, delivering far stronger physical bonding than standard dense nickel strike.
2. Ultra-Thin & Uniform Deposition Forms a consistent thin film (0.1–0.5 μm) with no over-build or edge accumulation. It preserves original part tolerance and dimensional accuracy for precision electronic and mechanical components.
3. Exceptional Adhesion Performance Eliminates common plating defects including blistering, peeling and delamination. The porous anchor structure firmly locks the top bright nickel coating, ensuring long-term coating stability under thermal cycling and mechanical stress.
4. Optimized Corrosion Resistance The uniform porous network disperses corrosive micro-current and avoids concentrated corrosion spots. It effectively blocks substrate oxidation, significantly improving the overall salt-spray resistance of the full nickel plating system.
5. Superior Surface Compatibility High chemical activity perfectly matches aluminum composite, steel and alloy substrates. It covers micro-pits and minor surface defects of base materials, supporting ultra-smooth, mirror-bright final nickel finish.
6. Stable Process Repeatability Controllable bath formulation and low-stress deposition produce consistent porous structure in mass production, ensuring uniform quality for batch manufacturing.
Standard nickel strike provides basic bonding; micro porous nickel strike delivers enhanced anchoring force, defect-free lamination and upgraded anti-corrosion performance, making it the preferred underlayer for high-end decorative and functional bright nickel plating.
