Nickel-Phosphorus Plating for Diamond Machining


Diamond machining is widely used in the optical industry to fabricate durable precision mold inserts for plastic optics. Nickel-Phosphorus plating is universally recognized and used world-wide as the hardest, most wear-resistant substrate for single point diamond turning (SPDT). Our electroplated nickel-phosphorus deposit is produced in a patented chemistry, originally developed for NASA's Marshall Space Flight Center at the University of Alabama in Huntsville. NiCoForm's implementation of this chemistry assures a fast and consistent plating rate with predictable and tightly controlled alloy properties. Our unique custom-developed activation steps assure perfect adhesion of the nickel-phosphorus layer to a variety of substrates - stainless and tool steels, brass, copper, aluminum, and many others.  Deposit thickness is not constrained, and due to the low-stress nature of the alloy can readily exceed, if necessary, 0.080" (2 mm). We are able to plate parts with a cross-section of up to 36" x 12" (900 x 300 mm). Detailed deposit properties can be found here.

Additional benefits of NiCoForm's Nickel-Phosphorus Plating are:


  • short turnaround times - 1-2 weeks for most inserts
  • excellent machinability of deposit with diamond and conventional cutters
  • outstanding diamond machined surface finish
  • very low diamond tool wear
  • defect- and void-free, smooth deposit
  • perfect adhesion to various substrates - Stainless and Tool Steels, Brass and other Copper Alloys, Aluminum, etc
  • improved deposit thickness uniformity
