Abstract
A droplet-free wear-resistant coating is manufactured by depositing a wear resistant nitride coating containing a nitride layer which contains at least one metal or metal compound of a metal selected from the group consisting of Ti, Cr, Al, Si and combinations thereof, on a surface of a substrate by cathodic-arc evaporation using a Venetian blind filter system in front of an arc cathode; to reduce metal microdroplets and/or metal microparticles in the wear resistant coating compared to an wear resistant coating obtained without a Venetian blind filter system.
