Wear resistance: Electroless Ni vs. Hard Anodizing

Q. I want to switch from hard black anodizing to e-less Ni on all of my Aluminum parts. Where can I find comparison data on wear and abrasion resistance for these two Aluminum finishing technologies?

A. Taber wear resistance

1. For hard anodizing: 1.5-0.5 mg/1000cycle (www.acteron.thomasregister.com/olc/acteron/03.htm)

2. For High Ni-P: 9-12 mg/1000cycle
3. For Ni-B: 3-9 mg/1000cycle (www.enla.com/properties.html)

All have good wear resistance, with hard anodizing the best followed by nickel-boron and high nickel-phos.
