In this preliminary study, a set of self-lubricating copper-tungsten disulfide (Cu-WS₂) composites are prepared via a powder metallurgy route to analyze the effects of solid lubricant concentration on their tribological, electrical and wettability properties. An extensive characterization is performed to preliminarily assess the potential application of these metal matrix composites (MMCs) in sliding electrical contacts working under harsh conditions. The experimental results reveal the beneficial effect of WS₂ on the wear behavior of the prepared composites, as demonstrated by friction coefficient, specific wear rate and wear coefficients results. A second phase content in the 10–15 wt% range appears to guarantee the better combination of the desired features.

在这项初步研究中，通过粉末冶金路线制备了一组自润滑铜-二硫化钨 (Cu-WS ₂ ) 复合材料，以分析固体润滑剂浓度对其摩擦学、电学和润湿性的影响。进行了广泛的表征，以初步评估这些金属基复合材料 (MMC) 在恶劣条件下工作的滑动电触点中的潜在应用。实验结果揭示了 WS ₂对制备的复合材料的磨损行为的有益影响，如摩擦系数、比磨损率和磨损系数结果所示。10-15 wt% 范围内的第二相含量似乎可以保证所需特征的更好组合。
