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.
CERTESS N Chromium Nitride coating is a hard (1800 HV) PVD film, which is typically deposited in the thickness range of 2 to 8 μm.
Chromium Nitride PVD coatings provide temperature resistance up to 700°C - higher than titanium nitride coatings. Like most HEF PVD coatings, CERTESS N is chemically inert.
Applications include stamping & forming dies; plastic and rubber molds, and mechanical components requiring high resistance to abrasive wear, sliding wear and chemical corrosion.
CERTESS N is an excellent hard chrome replacement.
