一种自润滑纳米复合涂层及其制备方法
摘要：
本发明属于薄膜材料领域，具体涉及一种Cr/Cu‑Pb‑Sn‑WS2自润滑纳米复合涂层材料及其制备方法。所述自润滑纳米复合涂层材料由过渡层和交替复合涂层组成，所述过渡层为Cr层，所述交替复合涂层为Cu‑Pb‑Sn‑WS2/Cr层，所述Cu‑Pb‑Sn‑WS2/Cr层是由Cu‑Pb‑Sn‑WS2靶和Cr靶交替沉积所得，所述Cu‑Pb‑Sn‑WS2靶的各组分按质量百分比计为：70％Cu、10％Pb、10％Sn和10％WS2。本发明采用Cr与Cu‑Pb‑Sn‑WS2交替沉积形成复合涂层，材料结构上比较新颖，且制备的涂层致密性较好，具有良好的抗粘着磨损性能，金属自润滑涂层的摩擦系数小，稳定在0.2以下。
摘要（英）：

The invention belongs to the field of film materials, and in particular, relates to a Cr/Cu-Pb-Sn-WS2 self-lubrication nanometer composite coating layer material and a preparation method thereof. Theself-lubrication nanometer composite coating layer material consists of a transition layer and an alternate composite coating layer; the transition layer is a Cr layer; the alternate composite coatinglayer is a Cu-Pb-Sn-WS2/Cr layer; the Cu-Pb-Sn-WS2/Cr layer is obtained by alternately depositing a Cu-Pb-Sn-WS2 target and a Cr target; and the Cu-Pb-Sn-WS2 target comprises the following componentsin percentage by mass: 70% of Cu, 10% of Pb, 10% of Sn and 10% of WS2. Cr and Cu-Pb-Sn-WS2 are alternately deposited to form a composite coating layer; the material structure is more novel; the prepared coating layer is better in compactness and excellent in adhesive wear resistance; and the friction coefficient of a metal self-lubrication coating layer is low, and is stabilized below 0.2.
