Consumerism in American Society and the Role of Government. Both high and medium phosphorus coatings offer superior corrosion resistance, hardness and wear resistance.

Accurate Precision Plating APP is a leading metal finishing services company, specializing in high quality, precision electroless nickel plating services for industrial applications. Call today to see how we can solve your plating challenges. APP offers electroless nickel plating services using high phosphorus and medium phosphorus coatings. They provide improved v656 resistance, especially for salt water environments, over medium phosphorus coatings, but lower hardness and wear resistance.

Abel Metal Processing, Inc.

To assure good performance of a Ni-P coating, the deposit quality must be inspected and evaluated during the chemical deposition process or in the end product. These studies began with Brenner and Riddel who developed, in the s, formulations for Ni-P deposition on carbon steel without using an electric current. At APP, we are committed to meeting or exceeding your expectations for your electroless nickel plating application through efficient, effective processes, high quality control and superior customer service.

Electroless Nickel Plating

MainierMaria P. Electroless nickel plating is used to apply precision coatings to complex shapes that require uniform coatings for both ID and OD surfaces. Joint deposition of nickel and phosphorus on a metallic surface carbon n656 without applying an external current is accomplished using cathodic reduction with hydrogen H from a reducing agent sodium hypophosphite and nickel salts.
