Method for preparing compound diamond-like carbon coating by using medium-frequency magnetic-control glow discharge method

The invention relates to a method for preparing a nano compound diamond-like carbon coating, which is realized in a way that: glow discharge is produced by using a medium-frequency magnetic-control sputtering target; argon and excessive hydrocarbon gases are introduced, so that the metal on the target surface reacts with the hydrocarbon gases to produce metallic carbides; when the argon ions bombard the target surface, the target surface sputters the metallic carbides; strong plasma produced by the glow discharge of the target surface ionize the hydrocarbon gases, so that the hydrocarbon gases produce highly-ionized carbon ions; and the carbides sputtered from the target surface and the highly-ionized carbon ions produced from the hydrocarbon gases form a high-hardness carbide-doped nano compound diamond-like carbon coating on a workpiece surface. The coating prepared by the invention has the characteristics of high hardness, strong adhesive force, high growth speed, high production efficiency, low depositing temperature, low production cost, simple equipment structure and the like; and diamond-like carbon coatings with different thicknesses can be prepared on hard alloy, high-speed steel and various other workpieces.
