Advantages of Nickel Boron:
Nickel Boron coatings are columnar in growth resulting in a distinct nodular topography which serves to reduce surface to surface contact of two mating / sliding surfaces reducing drag / friction. The nodular structure dissipates heat at greater efficiency due to greater surface area.
- Harder surface results in less wear
