黒ニッケル電気めっきの間違い

Even with expert technicians, it is possible to have problems when nickel-plating aluminum and black plating nickel. Examples of some of the missteps are:

• Inadequate surface cleaning: Dirt, grease, or oil that is present may inhibit sufficient adhesion, resulting in peeling or uneven layers.
• Eliminating pre-treatment of aluminum: The oxide layer on aluminum inhibits plating. When zincating or activation is not done correctly, weak plating is obtained.
• Bath or current temperature: Excessively high temperatures will cause the surface to burn, excessively low temperatures will cause low and weak plating.
• Failure to rinse well after plating: Leftover chemicals will result in streaks, dullness, or corrosion in the long run.
• Omitting sealing or post-treatment: This lowers the corrosion resistance and also lowers the life of the plated part.

It is possible to reduce the quality of electroplating black nickel results by paying attention to these pitfalls.

It is the base metal that is covered with the black nickel coating. Some of the common base metals are aluminum, steel, brass, and copper. Aluminum plating is a highly favored way of nickel plating on the grounds of the light weight of aluminum and its wide application in automobiles, electronics, and the decorative industry. Also, common plating is done on steel and brass so that they become less corrosive and durable to wear. The issue of the base metal is also very important to adhesion and durable outcomes.

ニッケル・ソース

The primary constituent of the plating bath is nickel ions. They are deposited in the base metal when an electric current is used. Typically, the nickel source is nickel sulfate, nickel chloride, or both. These additives provide a homogeneous covering on the electroplated black nickel.

黒ニッケル添加剤

The black nickel plating process needs certain additives to have the dark look. These can be organic or inorganic compounds that regulate the color, brightness, and uniformity. Additives play a role in the hardness and corrosion resistance of black electroplating nickel. It is important to have proper concentration to attain a uniform and desirable finish.

電解質溶液

The electrolyte solution is the medium that enables the movement of the nickel ions, which are deposited on the base metal. It is generally made up of water, nickel salts, acids, and the black nickel additives. The proper pH and temperature of the electrolyte are the key to uniform plating and avoiding other defects, such as streaks or uneven color.

正極および負極材料

In the plating process, the base metal is the anode, and a compatible cathode, which normally is stainless steel or lead, is used to complete the circuit. These materials make the process of deposition of black electroplating nickel smooth and even. High-quality electrodes will be selected to minimize contamination and increase the overall quality of the plating.
