ENHP can be heat treated after plating to improve the hardness and adhesion of the final coating. A high phosphorus (9%+) Electroless Nickel (EN), that is codeposited with PTFE. The electroless process deposits a uniform coating, regardless of the shape of the part, unlike electroplating that relies on current density. potassium perrhenate corresponding to 1. (1) and the corresponding peak position with grain size are given in Table 3. Electroless Nickel is an autocatalytic process that does not use electric current to produce the coating. Electroless nickel is not pure metal but other element(s) also derived from includes the reducing agent, such as or boron, or elements such as thallium, lead or phosphorus cadmium derived from other bath additives. Electroless nickel deposits, therefore, are not subject to the uniformity problems associated with electroplated coatings. As the above information indicates, electrolytic and electroless nickel are normally not interchangeable. As phosphorus levels increase, the hardness at as-deposited condition increases. The deposit uniformity allows plating of various coating thicknesses on any section of a part exposed to fresh plating solution. APP offers electroless nickel plating services using high phosphorus and medium phosphorus coatings.

Before heat treat-ment, however, most electroless nickel coatings consist largely of amorphous material. Electroless (chemical) Nickel-Phosphorus Plating is the most important catalytic process used in the last two decades. By increasing surface hardness, Electroless Nickel improves resistance to friction, wear and corrosion. Recent developments in the field of electroless nickel plating are outlined. Electroless nickel plating (EN) is an auto-catalytic reaction that deposits an even layer of nickel-phosphorus or nickel-boron alloy on the surface of a solid material, or substrate, like metal or plastic. Medium Phosphorus EN - Medium Phosphorus EN, MidPhos EN, is the most readily available type of EN. The process is used to deposit a smooth, bright high phosphorus coating on a variety of substrates. Allow dust or any particulate matter to enter the EN plating solution. High-phosphorous electroless nickel is dense and dull in comparison to the mid- and low-phosphorus deposits. Further, hydrogen embrittlement relief baking (for at least 3 hours) is required after plating on steels that have been heat-treated to a hardness above Rockwell C31. At low phosphorus levels, the electroless nickel coatings have high wear resistance and excellent corrosion resistance. Unlike electroplated coatings, electroless nickel is an auto catalytic process where the coating is deposited onto a part's surface by reducing nickel ions to metallic nickel with sodium hypo-phosphite. By far the most common form of electroless coating is nickel plating, which is actually a nickel-phosphorus alloy (2-10% P). The level of phosphorus dictates the hardness of the plating and corrosion resistance. Through a chemical reaction, the electrons required to reduce the nickel ions can be directly produced in the electrolyte solution by utilizing sodium hypophosphite , which is a type of reducing agent (see equations 1 and 2).
