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 USA: Wholly-owned subsidiary of the HEF Group charged with the Sales & Marketing of (a) chemicals / salts for Liquid Nitriding – which is a family of proprietary ferritic nitro-carburizing processes commercialized under the trade names of ARCOR®, MELONITE®, and QPQ; (b) Tribology testing services; and (c) engineered bushings for industrial applications.
TECHNIQUES SURFACES USA: Wholly-owned subsidiary of the HEF for commercial processing of PVD and CLIN technologies. In Jan 2011, TECHNIQUES SURFACES USA started its first industrial CLIN facility in Kearney, NE, currently dedicated to the processing to high-volume automotive components. Today TS USA operates three facilities in the US: Springfield, OH; Chattanooga, TN; and Kearney, NE.
