Experiment investigates friction performance of H-DLC film in salt lake brine, indicating its potential for prolonged equipment lifespan.
为延长盐湖卤水中设备零部件的使用寿命,本实验使用化学气相沉积法(PECVD)制备了含氢类金刚石薄膜(H-DLC),利用CSM摩擦试验机测试了盐湖卤水单组分溶液及模拟盐湖卤水环境中H-DLC薄膜的摩擦学性能。采用场发射扫描电子显微镜(FESEM)、扫描探针显微镜(SPM)的原子力模式(AFM)及拉曼光谱(Raman)等表征手段对摩擦实验前后H-DLC薄膜的形貌、组分、结构及其演变结果进行了研究。结果表明,在盐湖卤水单组分环境中,溶液浓度对薄膜摩擦学性能有较大影响。在NaCl溶液中,随着浓度升高,平均摩擦系数逐步增大。同时H-DLC薄膜能在盐湖卤水环境中表现出优异的摩擦学性能。研究结果将为H-DLC薄膜在盐湖卤水中的广泛应用提供更多的实验基础。
