This coating type consists of tungsten carbides embedded in a metallic matrix. The high level of hardness of more than 1,200 Vickers predestines them for all applications where extreme wear in of erosion, abrasion or adhesion is given.
TLS tungsten carbide coatings are now used as a standard for the hard chrome replacement. Application temperatures of up to about 450°C in oxidizing environments do not pose a problem. Through the addition of alloying elements, the coating corrosion resistance is considerably increased. The extremely dense coatings enable surface finishes up to high gloss quality.
