Electroless Nickel Plating

Industrial Electroless Nickel Plating (MIL-C-26074, AMS 2404, ASTM B-733 standards):

Advanced Surface Technologies specializes in high quality Electroless Nickel Plating. Electroless Nickel is a high quality engineering coating for corrosion resistance, hardness, lubricity, solderability and wear resistance. The advantage that Electroless Nickel has over almost all other plated coatings is the uniformity of the nickel deposit thickness. Without the high and low current density found in electrolytic plating processes, Electroless nickel can deposit into recesses without burning or having excessive thickness on the outer edges of a part. The coating conforms exactly to the surface finish of the part so cosmetic finishes will be enhanced by the Electroless Nickel deposit. Advanced Surface Technologies’ Electroless Nickel coatings conform to AMS2404, ASTM B733 and MIL-C-26074.

Being a leader in Electroless Nickel plating AST has 8 Electroless Nickel process lines that are substrate specific. Cleaning and alloy perpetration are extremely important to the quality of the Electroless Nickel deposit and using chemistries that are specifically designed to clean each alloy allows AST to provide the quality expected, even on the most difficult of parts.

There are many different types of Electroless Nickel coatings and processes available to meet a wide range of unique applications. Physical and mechanical properties vary considerably from one Electroless Nickel process to another depending on the phosphorus content, the formulation of the bath and both the pre-plate and post-plate treatments, yet all the Electroless Nickel coatings offer excellent deposit uniformity and superior corrosion protection.

Electroless Nickel plating is a chemical process that involves several simultaneous reactions in an aqueous solution, which occur without the use of external electrical power. The reaction is accomplished when hydrogen is released by a reducing agent (normally sodium hypophosphite), and oxidized thus producing a negative charge on the surface of the part. The charge causes a layer of nickel and phosphorus to form and this continues until the part is removed from the solution. Since the plating process requires no electrical current, the coating produced is a very uniform structure that can be applied over various metals and substrates.

Our experienced staff can construct custom solutions for your distinct finishing needs. If its corrosion protection, solderability, hardness, cosmetics or lubricity we can help you achieve the final product.

ELECTROLESS NICKEL PLATING

Electroless nickel is the preferred engineering coating solution for applications requiring high levels of corrosion and wear resistance, deposit uniformity and hardness, lubricity, and solderability. Electroless nickel plating is an autocatalytic chemical process used to deposit a uniform layer of nickel-phosphorous alloy onto stainless steel, copper, aluminum, or brass workpiece, without the necessity of applying electrical current.

Advanced Surface Technologies provides the highest quality electroless nickel plating services available for coating irregularly shaped parts, internal surfaces and cavities where assembly tolerances are critical, prototyping, and your other mission critical projects.

4 Decades of Custom Solutions for Your Unique Finishing Needs

By eliminating the electrical current necessary to perform traditional electrolytic plating processes, electroless nickel plating allows AST to place nickel deposits in hard-to-plate recesses without burning or excessive build up on the outer edges of parts. This unparallelled level of conformity to the plated surface, uniform thickness, and atomic-level smoothness enhances cosmetic finishes, allows repair or salvage of complex machine components, high tech applications such as computer hard drive coating, and other custom solutions for demanding applications in a wide range of industries.
