Attributes of PVD Coatings

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.
