TUNGSTEN CARBIDE FOR HARD MATERIAL COATINGS
Excellent abrasive resistance in dry machining under non-corrosive conditions
Significant reduction in friction
and adhesive wear
through WC / C coatings
With tungsten carbide coatings, it is possible to reduce fatigue behavior, wear and tear and the coefficient of friction despite high loads
Hardness 1600 HV
Layer thickness 2-5 µm
Maximum operating temperature 950 ° C
Coefficient of friction against steel 0.12-0.35
Excellent alternative to hard chrome coatings
Excellent interfacial adhesion with hydrogen-free carbon coatings
Efficient sliding wear resistance
Excellent cavitation resistance
Coating of end mills
Protective layers against abrasion and wear
Stamped and formed components
Planar and circular sputtering targets
With and without a binder
Great reduction in the coefficient of friction
Up to 300% longer service life of products through WC / C coatings
With tungsten carbide, sophisticated coatings are possible that:
are particularly hard and durable, and protect heavily used components, such as engine parts, from wear.
with hydrogen-free coatings are used in the weaving industry for reeds and thus achieve a 300% longer service life.
through protection increase the efficiency of rolling bearings against surface fatigue.
TO MEET THE HIGH MARKET AND CUSTOMER REQUIREMENTS
Carbide coatings that offer excellent interfacial adhesion to hydrogen-free carbon coatings through HiPIMS applications.
With special cathode configurations, no additional metallic interface layers are required on tools. This makes it possible, after a quick and thin tungsten-carbon interface layer, to begin coating hard amorphous carbon directly on the tools. This eliminates the need for environmentally harmful chrome plating.
