The abrasive wear behavior of SiC-p reinforced AA5052 MMC was investigated and compared with that of unreinforced AA5052. The worn surfaces were analysed by optical microscopy. The results show that at all applied loading conditions, SiC-p reinforced AA5052 MMC gives improved tribological properties as compared to the unreinforced AA5052; but the addition of SiC-p increases the density of the AA5052.

Introduction Metal Matrix Composite (MMC) is an engineering material developed by the macroscopic combination of reinforcement and matrix materials. MMCs exhibit outstanding mechanical and tribo- logical properties [1–3]. Aluminium Metal Matrix Composites (AMMCs) are a class of lightweight material having very good com- bination of strength to weight ratios. AMMCs are mostly used for weight critical applications like in aerospace, automobiles etc. [4–7]. Processing routes such as rolling, forging, extrusion forming are also applicable to particulate reinforced AMMCs. These result in development of isotropic properties when the particulates are distributed homogeneously [6,8]. Particulate reinforced AMMCs are more attractive due to their good combination of mechanical, tribological and corrosion behaviours at low cost [9]. The tribological properties of SiC-p reinforced AMMCs have been characterized by many researchers. Uzkut [10] has investi- gated the abrasive wear behavior of AA2011/ SiC-p MMCs fabri- cated by vortex method. He observed the wear resistance of the AA2011/SiC-p was higher as compared to unreinforced AA2011. When SiC-p content in AA2011 was increased, the wear resistance of the AA2011 composites increased, but decreased with the increasing abrasive grit size of the emery paper used. Idrisi and Mourad [11] have done wear analysis at different loads for differ- ent operating time of manufactured gears from AMMCs reinforced by SiC micro and nano particles. They found that wear increased with increase in load and operation time. Nano SiC-p reinforced AMMCs show more wear resistance as compared to micro SiC-p reinforced AMMCs. The improvement in wear resistance with increase in SiC-p content in Al matrix was also found by Pradhan et al. [12]. Patel et al. have investigated the wear resistance after replacing Zn content in the Al alloy by SiC-p and they also found that the wear resistance of the alloy improved [13]. In this study, the effect of applied load on abrasive wear behav- ior of 5 wt% SiC-p reinforced AA5052 MMC, effect of SiC-p on the density and porosity of AA5052 have been investigated. 2. Experimental studies 2.1. Materials and method In this present work, AA5052 with Mg content less than 3% has been chosen for the experiment due to its corrosion resistance and ability to achieve moderate strength. 5 wt% of SiC particles were used as reinforcement material due to their high hardness, high modulus of elasticity and low cost. The chemical compositions of AA5052 are listed in Table 1. https://doi.org/10.1016/j.matpr.2020.03.572 2214-7853/Ó 2020 Elsevier Ltd. All rights reserved.
