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.
Hardest (1500 - 4500 HV) known synthetic materials → High resistance to wear, abrasion and erosion.
Thin (2 to 5 microns) coatings – minimal impact on size tolerance of the coated component.
Low coating temeratures (150 – 250° C) – no distortion of coated component or loss of core hardness.
Low friction coefficients (0.1 – 0.5) – minimize friction losses and power consumption.
Line of sight process – difficult to coat cavities or IDs.
High Adhesion to a wide range of substrates – all steels including sintered, copper-alloys, titanium alloys, tungsten-carbide, plastics, glass
Ability of deposit alloyed and multilayered coatings.
Possible to mask regions on the component where no coating is desired.
Zero environmental impact – no effluents or discharges, no toxic chemicals.
