Zusammenfassung: | The invention belongs to the technical field of hard film products, and particularly relates to a multi-element hard film and a preparation process thereof. The preparation process of the multi-element hard film comprises the following specific steps of selecting a stainless steel substrate, carrying out bombardment treatment on the surface of the stainless steel substrate, sputtering and depositing a first film layer Cr layer, sputtering to generate a second film layer CrN layer, sputtering to generate a third film layer CrSiN layer, and sputtering to generate a fourth film layer CrSiCN layer. According to the preparation process of the multi-element hard film, magnetron sputtering and a plasma-assisted chemical vapor deposition process are effectively combined, so that the binding force and the performance of the hard film are greatly improved; besides, the prepared hard film is of a Cr/CrN/CrSiN/CrSiCN multi-element structure, an organic silicon precursor with a certain saturated vapor pressure is adopted |
