Applications of the Nitrotec process

Abstract

Nitrotec is a surface enhancement process for ferrous materials, the name being derived from the three basic process steps: nitriding, oxidation and protection. Nitriding produces a thin hard layer on the surface with excellent wear characteristics; controlled oxidation imparts an aesthetically pleasing black colour; and protection with a specially formulated organic sealant further increases the corrosion resistance. In addition to conferring superior wear and corrosion properties, the process enhances scuffing, scoring and galling resistance, friction properties and, in certain steels, increases tensile and yield strength. It is applied to components that include spindles, piston rods, pivot pins, cams, gears, brake rotors, calipers and shafts.
