Patent ID: 8382963

Claim:
A method for manufacturing a droplet-free wear-resistant coating, comprising: depositing a wear resistant nitride coating comprising a nitride layer comprising at least one metal or metal compound of a metal selected from the group consisting of Ti, Cr, Al, Si and a combination thereof, on a surface of a substrate by cathodic-arc evaporation using a Venetian blind filter system in front of an arc cathode; thereby reducing metal microdroplets and/or metal microparticles in said wear resistant coating compared to an wear resistant coating obtained without a Venetian blind filter system, wherein the filter system comprises Venetian blinds having a spacing of from 5 to 40 mm from one another, wherein a density of the metal microdroplets and/or metal microparticles with a geometric dimension of >1.5 μm in cross section is reduced by at least 75% in said coating, and wherein a deposition rate is 1.5 to 3.0 μm per hour.
