Abstract

A preparation method for a tungsten sulfide (WS) solid lubricating film based on high power impulse magnetron sputtering (HiPIMS) is provided. The preparation method includes the following steps: step 1: depositing a metal conductive film on a surface of a WStarget; step 2: using magnetic field sputtering to remove the metal conductive film in a target sputtering area on the surface of the WStarget, thereby obtaining a first WStarget; and step 3: performing the HiPIMS on the first WStarget to obtain the WSsolid lubricating film. The preparation method can achieve stable glow discharge of a WStarget and use the high deposition energy of HiPIMS to prepare the WSsolid lubricating film with high compactness and excellent wear resistance.
