Nanoplate 250 and 251
A COMPOSITE NANO-DIAMOND, ELECTROLESS NICKEL PLATING PROCESS
The 250 system is a version of Composite Diamond Coating® utilizing nanometer sized diamond in an electroless nickel process designed to deposit a uniform composite with ultra-fine diamond particles onto a great variety of metals, alloys, and non-conductors.
The 250 system is supplied in four liquid concentrates: Nano-Plate™ 250 A, 250 B, and 250 D are used for bath make-up and Nano-PlateTM 250 A, 250 T, and 250 D are used for replenishment.
Nano-PlateTM is also available in a lead and cadmium free Nano-PlateTM 251 version to meet a number of environmental regulations.
Some advantages of the 250 system are:
- Deposits with exceptional wear resistance surpassing chrome plating
- Corrosion resistance
- High plating rate
- Excellent stability and bath life
- Ease of use comparable to conventional electroless nickel
he 250 system electroless nickel processes meet or exceed MIL-C-26074D and AMS 2404C.
