Melonite - Ferritic nitrocarburizing is a range of case hardening processes that diffuse nitrogen and carbon into ferrous metals at sub-critical temperatures.
NiB - Alkaline Electroless Nickel Boron (NiB) is an autocatalytic coating process. The coating is deposited from an aqueous solution which contains either an alkylamineborane or sodium borohydride as a reducing agent, a source of nickel Ions, a buffer, complexant, and control chemicals. 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.
