The purpose of this paper was to investigate the Ni-P coating process, to evaluate the bhaviour of Ni-P in a saline environment using aqueous brine 3. They provide improved corrosion resistance, especially astj salt water environments, over medium phosphorus coatings, but lower hardness and wear resistance. It is used for shafts, piping, ducts, molds, dies, enclosures, bores and processing equipment.

The recommended test parameters are: TavaresJuan M.
Consumerism in American Society and the Role of Government. Our staff’s superior customer service, attention to detail v656 commitment to quality produces the superior product that has built APP’s reputation in the industry. Scientific Research An Academic Publisher. APP ashm electroless nickel plating services using high phosphorus and medium phosphorus coatings. 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.
They aastm bright coating, with hardness of Rc that can be increased to Rc with heat treating. Joint deposition of nickel and phosphorus on a metallic surface carbon steel without applying an external current is accomplished using cathodic reduction with hydrogen H from a reducing agent sodium hypophosphite and nickel salts.
Accurate Precision Plating APP is a leading metal finishing services company, specializing in high quality, precision electroless nickel plating services for industrial applications. Our extensive quality control measures throughout production include non-destructive testing in accordance with ASTM B to measure the thickness of the coating. The corrosion resistance of nickel-phosphorus Ni-P coatings and their mechanical properties in seawater have led inestigations into the development of new technologies and the replacement of some special alloys in equipment used in oil production, such as valves, tubing, sucker rod joints, pumps, riser, manifolds and subsea Christmas trees.

You can be assured your electroless nickel plating project will be completed to your exact specifications and to the tightest tolerance the first time and your part delivered to you production-ready. Both high and medium phosphorus coatings offer superior corrosion resistance, hardness and wear resistance.
Electroless nickel plating is used to apply precision coatings to complex shapes that require uniform coatings for both ID and OD surfaces. Call today to see how we can solve your plating challenges. 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.
