Abstract:
1. A multilayer film prepared by magnetron sputtering coating comprising: a transition layer on a substrate, the transition layer including a titanium layer and a mixed layer of titanium carbide and quasi-graphite on the titanium layer; a composite layer on the transition layer, the composite layer including a multilayer structure with a quasi-graphite layer and a diamond-like carbon layer alternately laminated, wherein the quasi-graphite layer includes 60% of materials by mass with a sp a diamond-like carbon layer on the composite layer, wherein in a direction from the substrate to the diamond-like carbon layer, the mass percentage of titanium in the mixed layer of titanium carbide and quasi-graphite is gradually decreased, while the mass percentage of carbon is gradually increased.
