Abstract
Official abstract text for this publication.
The invention relates to a method for producing a metal component coated by a hard-material coating, which method comprises the method steps of preparing an anti-caking agent, adding the prepared anti-caking agent to a powder mixture, providing the powder mixture, providing the substrate made of metal, heating the powder and the substrate in a heating device, depositing a coating on the substrate, the coating having a higher hardness than the substrate, and cooling the substrate.
First claim
Opening claim text (preview).
What is claimed is: 1. A metal component, comprising: a substrate made of steel; and a hard-material coating made of a metal carbide or a metal nitride or mixtures thereof, said hard-material coating applied on a surface of the substrate and having embedded therein particles of an anti-caking agent containing aluminum silicate, aluminum oxide, silicon oxide, or zirconium oxide, wherein in a micrograph of the hard-material coating, the particles of the anti-caking agent embedded in the hard-material coating have a diameter between 0.1 and 2 μm and a surface content of less than 15%. 2. The metal component of claim 1 , wherein the hard-material coating includes CrN, FeN or VN. 3. The metal component of claim 1 , wherein the particles of the anti-caking agent embedded in the hard-material coating have a surface content of less than 10%. 4. The metal component of claim 1 , wherein the particles of the anti-caking agent embedded in the hard-material coating have a surface content of less than 5%. 5. A chain component, comprising: an inner plate having a sleeve an outer plate extending in parallel with the inner plate, and a stud rotatably fastened in the sleeve of the inner plate and interconnecting the outer plate to an adjacent inner plate, wherein a link surface of the stud in contact with the sleeve comprises a hard material coating made of a metal carbide or a metal nitride or mixtures thereof, said hard-material coating applied on the link surface of the stud and having embedded therein particles of an anti-caking agent containing aluminum silicate, aluminum oxide silicon oxide, or zirconium oxide, wherein in a micrograph of the hard-material coating, a surface content of the particles of the anti-caking agent in the hard-material coating having a diameter between 0.1 and 2 μm is less than 5%.
