Electroless Nickel is an autocatalytic chemical process used to deposit a uniform layer of nickel-phosphorus or nickel-boron alloy onto a substrate without the need for an external electrical current. The properties of the coating are dependent on the phosphorus content of the deposited alloy.
Key Features:
• Hardness: High hardness, up to >1000 HV after heat treatment.
• Corrosion Resistance: Excellent protection against corrosion.
• Wear Resistance: High resistance to wear and tear.
• Uniform Coating: Provides a uniform thickness even on complex geometries.
Phosphorus Content:
• Low-Phosphorus (2–4%): Microcrystalline structure, high hardness.
• Mid-Phosphorus (6–9%): Balanced properties for general applications.
• High-Phosphorus (>10.5%): Amorphous structure, excellent corrosion resistance.
Applications:
• Corrosion Protection: Ideal for environments requiring high resistance to corrosion.
• Wear Protection: Used in applications where durability is critical.
• Metallization: Suitable for non-conductive materials like ceramics and plastics.
• Electronics: Commonly used in PCBs and electronic components.
• Substitute for Hard Chromium Plating: Offers an alternative to traditional hard chrome plating.
