Heat treatment of nickel-phosphorus deposits can cause significant changes in properties and structure. X-ray dif-fraction examination shows substantial crystallinity and
TROUBLESHOOTING PLATING ON PLASTICS
www.plateworld.comAlthough the electroless copper plating systems are similar to those used in printed circuit processing, electroless nickel processes differ greatly from those used in metal plating and are not interchangeable. Room temperature nickel solutions are mildly alkaline and give a low and uniform deposition rate. At present, automotive and other

High Quality Electroless Nickel Plating - astfinishing.com
www.astfinishing.comElectroless nickel plating is an autocatalytic chemical process used to deposit a uniform layer of nickel-phosphorous or nickel-boron alloy onto a plastic, stainless steel, copper, aluminum, or brass workpiece, without the necessity of applying electrical current.
Chapter The Fundamental Aspects Of Electroless Nickel Plating
www.tau.ac.ilThe fundamental Aspects of Electroless Nickel Plating 3 In 1844, Wurtz (2) observed that nickel cations were reduced by hypo- phosphite anions. However, Wurtz only obtained a black powder. The first bright metallic deposits of nickel-phosphorus alloys were obtained in 191 1 by Breteau
