The invention discloses a nanometer multi-layer structure WSx/DLC lubricating film and a manufacturing method. The manufacturing method mainly comprises the steps that 1, a base body is subjected to pretreatment, so that the surface of the base body is clean and smooth; 2, a WS2 target, a graphite target and the base body obtained after pretreatment are installed in a multi-target magnetron sputtering deposition system, air pressure of a deposition chamber is drawn to be below 1.5*(10-3)Pa, the target base distance and the base body direct current negative bias voltage are adjusted, high-purity argon is introduced, and stable air pressure is obtained; and 3, the base body is heated to a certain temperature, then the WS2 target and the graphite target serve as sputtering target materials, a WSx film and a DLC film are deposited on the surface of the base body in an alternating manner, parameters such as the modulation period of the multi-layer film, the thickness of the DLC film and the film thickness are controlled through deposition time, and therefore the WSx/DLC nanometer multi-layer film with the specific structure is obtained. The method is simple in technology and good in economy, the manufactured nanometer multi-layer film is high in hardness (t,9.5GPa), good in binding force (t,36N), and small in internal stress (1t,370MPa), the wear-resisting property is excellent in vacuum and humidity atmosphere environment (the friction coefficient in atmosphere and vacuum is lower than 0.17 and 0.1, and the wear rate is 1t,3*(10-15)m3/Nm order), environmental sensitivity of the tribology property is reduced remarkably, and the film has a good application prospect.
