Whether you're responsible for a factory's operations or do some personal metalwork, electroless nickel plating is a metal treatment process that can help you increase the durability and life spans of a variety of products and industrial components. In fact, nickel plating is the coating of choice for machinery that is operated in high-friction or corrosive environments, including drilling equipment and machine tools. Below is an overview of nickel plating and why it may be the best choice for your business.

Common Questions About Electroless Nickel Plating

1. What is it?

Electroless plating produces a layer of nickel-alloy on the surface of an object without the application of an electrical current. Instead, the object is submerged in a nickel-phosphorus solution, which has a positive current. The positively charged ions are naturally drawn to the substrate, depositing a thin, uniform layer of nickel across the entire surface.

2. What are the benefits?

Electroless nickel plating produces an extremely hard, durable surface with greater wear resistance than electroplating. The uniformity of the nickel layer makes this process ideal for small parts or components with intricate shapes that require precise application. Nickel plating also increases the life span of a component since the coating protects the part from corrosion and friction and can be replaced when it eventually wears down.

3. What are its most common applications?

Electroless nickel coatings are found in almost every industry, from automotive manufacturing to common household power tools. The added durability and corrosion resistance make it a popular option for petrochemical exploration, warehouse and material handling equipment, and the aerospace field. However, any business that wants to extend the useful life of its metal equipment should consider investing in electroless nickel plating.

4. How does it compare to chrome plating?

Both nickel and chrome plating create exceptionally hard surfaces capable of withstanding intense pressure and harsh operating conditions. However, chrome is somewhat harder, so it may be the better option for applications that require maximum durability.

Additionally, nickel produces a more uniform surface, while chrome may need to be sanded smooth after application. This makes electroless nickel plating a better option for objects with blind holes, which can be difficult to coat with electrolyte plating processes. Without the proper treatment, these areas are vulnerable to corrosion and wear in extreme operating conditions.
