Types Of Nickel Plating Processes

Jul 04, 2025

Nickel plating process is a method of improving the corrosion resistance, hardness, aesthetics, and other properties of materials by depositing a layer of nickel on metal or certain non-metal surfaces. The nickel plating process is mainly divided into two types: electroplated nickel plating and electroless nickel plating.

Nickel plating process method Electroplated nickel plating Chemical nickel plating
Basic Introduction Electroplated nickel plating is a method of depositing a layer of nickel on a metal surface through electrochemical action. Chemical nickel plating is a process in which nickel ions in an aqueous solution are reduced by a reducing agent under certain conditions and deposited onto the surface of a solid substrate.
Pre treatment: Clean, remove oil, rust and other treatments on the plated parts to ensure a firm bond between the coating and the substrate. Similar to electroplating nickel, cleaning, degreasing, rust removal and other treatments are carried out on the plated parts.
Preparation of plating solution: Prepare an electrolyte composed of nickel salt (main salt), conductive salt, pH buffer, wetting agent, etc. Prepare a chemical nickel plating solution containing nickel ions and reducing agents.
Electroplating operation: Using the plated part as the cathode and a pure nickel plate as the anode, place it in the electrolyte and apply direct current to reduce and deposit nickel ions on the cathode surface, forming a nickel coating. Place the plated part in a plating solution, and under certain temperature and pH conditions, nickel ions are reduced by a reducing agent and deposited on the surface of the plated part, forming a nickel coating
Post treatment: Conduct quality inspection on the coating, such as measuring the thickness and corrosion resistance of the coating, and perform necessary cleaning and drying treatment. Similar to electroplating nickel, quality inspection and post-treatment are carried out on the coating.
The advantages:  uniform and dense coating, good corrosion resistance, wear resistance, and glossiness. ood coating uniformity, high hardness, excellent wear resistance and corrosion resistance, and no need for DC power supply and complex electroplating equipment.
