1. Nickel Boron (NiB) coatings are harder than Nickel Phosphorus (NiP) coatings. 2. Surface topography is very different between NiP and NiB coatings. 3. Adhesion forces between the two contacting surfaces play into wear properties - the surface topography is a contributor to the wear results. 4. Under abrasive wear conditions, nickel boron coatings offer a improvement over nickel phosphorus coatings. 5. The addition of PTFE to NiP plating lowers its abrasion resistance. 6. The addition of BN will increase the abrasion resistance of NiB or NiP platings. 7. The addition of diamond to a NiB plating will improve its resistance to low stress abrasion. 8. The addition of diamond to a NiB plating will improve its resistance to low stress abrasion.
