Wear Resistance of Duplex Coated Cr-Mo-V Alloyed Steel
Original language description
The requirements for materials used in the machine parts production, especially their functional characteristics and service life are currently increasing. Thin ceramic coatings deposited on the surface of tools and machine parts by PVD methods improve considerably their tribological properties. These hard brittle coatings can be damaged rapidly if a plastic deformation initiates in the substrate near the coating-substrate interface when subject to relatively high intensity loading. Therefore, the strengthening of substrate surface layers, e.g. by plasma nitriding, appears to be a suitable solution of the low strength of the substrate. The paper resumes results of tribological testing of duplex coating tool steels. Steel samples (31CrMoV9) were nitrated and subsequently treated by PVD process. There were deposited different coatings (TiN, CrN, TiAlN and multilayer 3x(CrN-TiN)) with thickness 1 and 3?m. Samples were tested and characteristics like nanohardness, hardness of duplex coatin
