Electroless Nickel Plating

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.

The recommended test parameters are: They provide bright coating, with hardness of Rc that can be increased to Rc with heat treating. 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.

Consumerism in American Society and the Role of Government. 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.

Electroless nickel plating is used to apply precision coatings to complex shapes that require uniform coatings for both ID and OD surfaces. Joint deposition qstm 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.

TavaresJuan M. Both astj and medium phosphorus coatings offer superior corrosion resistance, hardness and wear resistance. 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.

Scientific Research An Academic Publisher. Go to Navigation Go to Content. To assure good performance of a Ni-P coating, the deposit quality must be atm and evaluated during the chemical deposition process or in the end product.

MainierMaria P. Our extensive quality control measures throughout production include non-destructive testing in accordance with ASTM B to measure the thickness of the coating. APP offers electroless nickel plating services using high phosphorus and medium phosphorus coatings.
