About Us
Report
TS USA now has a Liquid Nitriding facility in Phoenix, AZ operating under the name of TS WEST. The HEF Group, based in France, has been a global leader in the science of tribology (wear & friction) for more than 50 years. Established as a research and development company, HEF subsequently applied its knowledge and experience to develop surface engineering solutions for improving the performance of industrial and automotive components.
Process Steps
Report
Oxynit is a post-nitrocarburizing molten salt bath treatment that provides added corrosion protection by oxidizing the porous zone of the iron nitride compound layer into stable iron oxides (Fe3O4) - also called magnetite. Oxide layer also provides a black aesthetic appearance. 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.
Nitriding Portfolio
Report
ARCOR V is default ferritic salt bath nitriding process used by HEF. This process provides two valuable benefits: a dense epsilon iron nitride compound layer with limited porosity, and processing temperatures that minimize thermal distortion or loss of core hardness of the treated component - without a significant compromise of throughout and productivity.
Faq
Report
Liquid Nitriding (LN) is a common term for a diffusion process that is actually liquid nitrocarburizing; a thermo-chemical reaction whereby nitrogen, primarily, and some carbon are diffused into the surface of iron-based materials. The nitrogen combines with the iron to form an iron-nitride compound layer that provides improved surface properties; e.g.
