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 EN coatings and processes available to meet a wide range of unique applications. Physical and mechanical properties vary considerably from one EN 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 EN coatings offer excellent deposit uniformity and superior corrosion protection.
EN 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, soulderability, hardness, cosmetics or lubricity we can help you achieve the final product.
