In this study, powder metallurgy process has been utilized to produce the composite materials. Pure aluminium (Al) has been selected as the matrix material for the preparation of composite materials. 4% of magnesium (Mg) has been added as the alloying element, whilst molybdenum disulphide (MoS₂) is reinforced with a varying wt.% (2, 4 & 6). The intent of this work is, to evaluate some basic mechanical properties (density, microhardness, compression strength and toughness), surface degradation properties (corrosion and wear), and electrical conductivity of the fabricated composite materials. Moreover, SEM mapping and EDAX analysis have been conducted to confirm the presence of reinforcement particles with homogenous distribution in the matrix material and to do the fractographic study of the compressive strength tested samples. The density of the composite material Al-4% Mg-6%MoS₂ has been increased compared to the density of pure Al material. Micro Vickers hardness test shows that Al-4% Mg-6%MoS₂ composite has 32.86% more hardness as compared to that of pure Al material. Compressive strength of the composite material with the higher wt.% of MoS₂ is found to be 181.81 N/mm², while Al material has only 167.52 N/mm². The buckling formation during the compression test is avoided in the composite material owing to the existence of MoS₂ particulates. The wear loss of composite materials is found low as compared with the unreinforced Al material, owing to the solid lubricant property of MoS₂ particles, and hence, coefficient of friction (COF) is also lessened with the increase in the MoS₂ wt.%. Also, the MoS₂ reinforced materials show good resistance to corrosion due to the presence of molybdenum, which acts as a consistent layer obstacle to prevent the surface from further degradation.

在这项研究中，粉末冶金工艺已被用于生产复合材料。纯铝（Al）已被选作制备复合材料的基质材料。已添加4％的镁（Mg）作为合金元素，而二硫化钼（MoS ₂）以不同的wt。％（2、4和6）进行增强。这项工作的目的是评估制造的复合材料的一些基本机械性能（密度，显微硬度，压缩强度和韧性），表面降解性能（腐蚀和磨损）以及电导率。此外，已经进行了SEM映射和EDAX分析，以确认基体材料中均质分布的增强颗粒的存在，并对受压强度测试样品进行了分形研究。与纯Al材料的密度相比，复合材料Al-4％Mg-6％MoS ₂的密度增加了。Micro Vickers硬度测试表明，Al-4％Mg-6％MoS ₂复合材料的硬度比纯铝材料高32.86％。发现具有较高MoS ₂重量％的复合材料的抗压强度为181.81N / mm ²，而Al材料仅具有167.52N / mm ²。由于存在MoS ₂颗粒，可以避免复合材料在压缩测试过程中产生屈曲。由于MoS ₂颗粒的固体润滑性能，与未增强的Al材料相比，复合材料的磨损损失较低，因此，随着MoS ₂ wt。％的增加，摩擦系数（COF）也降低了。另外，MoS ₂ 增强材料由于存在钼而具有良好的耐腐蚀性，而钼则是防止表面进一步降解的稳定层障碍。
