Placage de nickel chimique

Electroless nickel plating (ENP) is a reliable surface finishing solution for demanding applications where consistent coating, corrosion protection, and improved hardness are essential. At Yicen Machining, we apply ENP to parts with complex geometries and tight tolerances ensuring a durable, uniform finish without the use of electricity.

Whether your components operate in aerospace, oil & gas, automotive, or electronics environments, our electroless nickel plating ensures maximum wear resistance, dimensional control, and part longevity.

Yicen’s Electroless Plating Process

1. Pre-Treatment – The part is cleaned and activated to remove contaminants and oxides.
2. Immersion Plating – The component is submerged in a heated bath containing nickel salts, a reducing agent, and stabilizers.
3. Controlled Deposition – The plating forms evenly across all surfaces, including threads and blind holes.
4. Rinse & Dry – The part is carefully rinsed and dried to complete the process.

Why Choose Electroless Nickel Plating?

Yicen Machining recommends ENP for high-performance parts where precision and protection are essential. Key benefits include:

• Uniform Coating – Delivers even coverage across complex shapes and recessed features.
• Superior Corrosion Resistance – Especially with high-phosphorus variants; ideal for marine and chemical environments.
• Excellent Wear Resistance – Medium- and low-phosphorus coatings offer exceptional abrasion performance.
• Tight Tolerance Control – Coating thickness is precisely managed to protect critical dimensions.
• Enhanced Lubricity – Reduces friction in sliding parts, improving functionality.
• Non-Electrical Application – Suitable for coating non-conductive materials (with pretreatment).
• Heat Treatable – Hardness can exceed 950 HV (68+ HRC) when post-treated.

Compatible Materials for ENP

Electroless nickel plating works on a variety of substrates, including:

• Steel and stainless steel
• Aluminum and aluminum alloys
• Copper, brass
• Titanium (with proper surface preparation)
• Plastics (after metallization)
