Abstract
The present invention relates to a wear-resistant layer, which is preferably used on piston rings for internal combustion engines. The wear-resistant layer comprises: 15-25% by weight iron (Fe), 10-25% by weight tungsten carbide (WC), 30-40% by weight chromium (Cr), 10-25% by weight nickel (Ni), 10-25% by weight molybdenum (Mo), 1-10% by weight carbon (C), 0.1-2% by weight silicon (Si), wherein Cr is present in elemental form and/or as a carbide in the form of CrC. A method for applying the wear resistant layer and a piston ring having such a wear resistant layer are also disclosed.
