Abstract (en)
[origin: AT507215A4] A wear-resistant material comprises (in weight%) carbon (0.3-3.5), nitrogen (0.05-4), oxygen (0.002-0.25), niobium/tantalum (3-18), and remainder of metallic elements and impurities. A microstructure of the material comprises a metal matrix and hard phases embedded in the matrix. The hard phases comprise carbide, nitride, carbonitride and/or oxide carbonitride, where hard phases have diameter of 0.2-50 mu m. An independent claim is also included for a method for producing a wear-resistant material.
