The easy oxidation and poor corrosion resistance of the sputtered WS₂ film would limit its application in spacecraft due to the sharp deterioration of lubricity resulting from the contact with the marine atmosphere inevitably with the increasing space launch from sea or seaside. In this study, the active metal Ta was skillfully introduced into the WS₂ film through co-sputtering of the WS₂ and Ta targets. The influence of the doped Ta related microstructure regulation on the tribological and anti-corrosion properties of the prepared composite films was investigated. It showed that the incorporation of the active Ta would activate the residual O atoms to form Ta₂O₅ phase while making the WS₂ phase partly oxidized to form the WS_xO_y and WO₃. WS₂–Ta composite films with low Ta content exhibited low friction coefficient and long wear life more than 3 times of that for pure WS₂ film. In addition, the corrosion resistance of WS₂–Ta film was improved by a positive shift of corrosion potential in salt spray with increasing the Ta content, originating from the passivation effect of the Ta₂O₅ phase and the WS_xO_y phase in the film as well as the dense structure.

溅射的WS ₂薄膜易氧化、耐腐蚀性能差，随着越来越多的海上或海边空间发射，不可避免地与海洋大气接触导致润滑性急剧恶化，从而限制了其在航天器中的应用。在本研究中，通过 WS ₂和 Ta 靶的共溅射，将活性金属 Ta 巧妙地引入到 WS ₂薄膜中。研究了掺杂 Ta 相关的微观结构调节对制备的复合膜的摩擦学和抗腐蚀性能的影响。结果表明，活性 Ta 的掺入会激活残留的 O 原子形成 Ta ₂ O ₅相，同时使 WS ₂相部分氧化形成WS _x O _y和WO ₃。低Ta含量的WS ₂ -Ta复合薄膜摩擦系数低，磨损寿命长，是纯WS ₂薄膜的3倍以上。此外，由于Ta ₂ O ₅相和WS _x O _y相的钝化作用，随着Ta含量的增加，WS ₂ -Ta膜的耐腐蚀性能通过盐雾腐蚀电位的正移而提高。薄膜以及致密的结构。
