BENEFITS OF ELECTROLYTIC NiP PLATING

1. Low deposition temperature for low stress deposits - safer, economical
2. 104 - 140° F (40 – 60° C) for Nickel Cobalt Phosphorus with 11% Phosphorus
3. 113 – 140° F ( 45 – 60° C) Nickel Phosphorus with 11%  to 13% (Wt%) Phosphorus
4. Low maintenance
5. pH 2.50 - 3.0, 2.75 nominal 
6. Nickel or Nickel + Cobalt Anodes
7. No metal additions (anodes provide metal)
8. Phosphorous added at 1:1 addition:consumption (instead of 5:1 as in electroless)
9. Low water consumption, solution remains covered while plating
10. Constant and predictable plating rates from 5 to 50 micrometers/hour
11. Low ventilation requirements
12. Extended life similar to standard nickel plating without rejuvenation
13. No solution phase precipitation (no crashes)
14. No tank or equipment stripping
15. Extended filter life
16. Unattended electrodeposition
17. No nickel hydroxide precipitation due to pH adjustment
18. Much safer process than electroless nickel for operator
19. Engineered properties
20. May be tailored from non-magnetic to highly magnetic
21. Glassy nickel properties with high phosphorus content
22. Free machining alloys using diamond or other tools for optics
23. Corrosion resistant alloys similar to electroless nickel
24. Decorative blue oxides or non-reflective black oxide possible
