摘要（英）：

The invention discloses an Al-Cu-N wear-resistant hard coating, comprising an AlN crystal phase and a Cu crystal phase, wherein the Cu crystal phase is dispersed in the AlN crystal phase, the interface between the Cu crystal phase and the AlN crystal phase is bonded through a Cu-Al bond, and the Al-Cu-N wear-resistant hard coating is composed of, on the basis of atomic percentage, 74.6 to 89% of Al and N with and 11 to 25.4% of elemental Cu. The Al-Cu-N wear-resistant hard coating has good hardness and excellent wear resistance; the wear rate of the coating is less than 4.0 * 10<-16> m3/Nm, meeting requirements for wear resistance; and the coating can be extensively used in fields like dies and machine parts. The invention further discloses a preparation method for the Al-Cu-N wear-resistant hard coating. The method adopts magnetron sputtering, has good operationality and controllability, can easily realize industrial production and has wide application prospects and good economic benefits.
