The LN process is carried out in equipment manufactured by HEF and customized to the nature of the applications under consideration – the size and shape of components to be nitrided; the throughput rate required; process steps required to achieve the desired nitriding specifications; and environmental considerations. A schematic view of a typical ARCOR® process line is shown below:
Liquid nitriding is a subcritical surface enhancement process with one of the longest track records of success of any case hardening technology.
PVD coatings involve the deposition of thin (2-10 microns; 0.0001" – 0.0004") films on the surface of tools and components.
HEF bushings are recognized worldwide for their excellent frictional and anti-seizure properties, and ability to withstand high loads.
