Beschreibung
Zusammenfassung:	The invention discloses a hard film printing plate and a preparation method thereof, the hard film printing plate comprises a metal base material and a hard film layer arranged on the surface of the metal base material, the hard film layer sequentially comprises a Cr transition layer, a CrN layer, a CrSiN layer and a CrSiCN layer from inside to outside, and the structure of the hard film layer is Cr/CrN/CrSiN/CrSiCN. The vacuum coating process is combined with magnetron sputtering and reactive sputtering, the hard film layer of a multi-layer structure is deposited on the surface of the printing plate, the hardness and corrosion resistance of the hard film layer are higher than those of a traditional electroplating chromium-plated layer, the use range of the hard film printing plate is widened, and the hard film printing plate has the higher use printing endurance rate and the longer service life and is suitable for large-scale popularization and application. And favorable conditions are created for reutilizat
