摘要

本实验研究了通过冷喷工艺开发的镍基复合涂层的摩擦和磨损特性。在开发的涂层中,加入了固定浓度的 MoS2(10 wt.%)和不同浓度的 Ag(5、10 和 15 wt.%),以评估增强元素的润滑潜力。在室温(RT)条件下,试样以 0.3 米/秒的固定滑动速度在不同载荷(6、11、16、&;21 牛顿)下滑动。调查显示,随着测试载荷从 6 牛顿增加到 16 牛顿,所有参与研究的复合涂层都显示出较低的摩擦系数(COF)和磨损率,超过这一载荷后,在 21 牛顿之前则出现了相反的趋势。上述涂层之所以具有优异的摩擦学特性,与固体润滑剂(Ag 和 MoS2)的协同作用以及在磨损轨道上形成三聚层时最佳的 Ag 重量百分比密切相关。

Tribological behavior of Ni-based composite coatings produced by cold spray
The current experiment examined the friction and wear characteristics of Ni-based composite coatings developed by cold spray route. In the developed coatings, fixed concentration of MoS2 (10 wt. %) and varying concentrations of Ag (5, 10, and 15 wt. %) were incorporated to evaluate the lubricating potential of reinforcing elements. The specimens were slid in various working regimes of loads (6, 11, 16, & 21 N) and at a fixed sliding speed of 0.3 m/s under room temperature (RT). According to the investigation, all participating composite coatings have revealed a lower coefficient of friction (COF) and wear rate as the testing load increased from 6 to 16 N, beyond which a reverse trend was recorded till 21 N. However, composite coating with 10 wt. % Ag has shown excellent tribological properties in terms of the lowest COF (0.29) as well as wear rate (4.0 × 10−5 mm3/Nm) at 16 N and 0.3 m/s. The superior tribological characteristics of the aforesaid coating have been explained and well connected to the synergistic effect of solid lubricants (Ag and MoS2) as well as the optimal weight percent of Ag in the creation of tribo layer on the wear track.
