摘要
固体润滑剂粉末是最重要的粉末之一,用于在相对运动的情况下保护表面免受损害,减少它们之间的摩擦和磨损。在本研究中,纯度为99%的二硫化钼(MoS2)纳米颗粒由于具有低摩擦系数和高耐磨性而被用作固态润滑剂。其中,二硫化钼颗粒分布为1.69 x 1015颗粒/ m2,在钢盘的表面上,使用针盘摩擦试验机对钢销进行摩擦。采用针盘技术研究了空气和湿度条件下mos2分布颗粒的摩擦系数行为和针盘在钢盘表面的位置深度。它被用来检查钢销在没有MoS2纳米粒子分布的钢盘表面上的摩擦学行为,也用于钢销在有MoS2纳米粒子分布的钢盘上的摩擦学行为。然后,利用扫描电子显微镜(SEM)对二硫化钼纳米颗粒的形貌和微观结构进行了表征。结果表明,纳米二硫化钼在钢盘表面的分布比钢销表面具有更低的摩擦系数和更高的耐磨性。
Generalization of (0,2,5)Lacunary interpolation by sixtic splines on uniform meshes
A solid-state lubricant powders is one of the most significant powders usedto protect surfaces from damage in cases of relative motion, with a reduction in thefriction and wear between them. In this study, molybdenum disulfide (MoS2),purity 99%, nanoparticles have been used as solid-state lubrication, due to it havinga low coefficient of friction and high wear resistance. In which MoS2 particles havebeen distributed with 1.69 x 1015 particles per m2 over the steel disc’s surfaceagainst the steel pin using a pin on disc tribometer machine. The pin on disctechnique was used to study the friction coefficient behaviour of the MoS2distribution particles and the position depth of the steel pin on the steel disc surfacewhen the ambient environment was air and humidity. It was used to examine thetribological behaviour of the steel pin on the steel disc surface with no distributionof MoS2 nanoparticles and also for a steel pin on steel disc with a distribution ofMoS2 nanoparticles. Then, the morphologies and microstructures of thedistributions of MoS2 nanoparticles were characterized using Scanning ElectronMicroscopy (SEM). In a result, the distribution of MoS2 nanoparticles have resultedin a lower friction coefficient and higher wear resistance compared with only steelpin on steel disc surfaces.
