Analysing the Mechanical Properties and Corrosion Phenomenon of Reinforced Metal Matrix Composite

Abstract In this research, a Metal Matrix hybrid composite (MMHC) is prepared by reinforcing the following reinforcements like Graphite, Aluminium oxide, silicon carbide and boron carbide at a percentage of 4 and 5 is added with A6061. This preparation is carried out by using the stir casting method. In particular, the corrosion properties of the untreated A6061 reinforced composites samples were evaluated using in 3.5% NaCl solution and immersion tests in 1% HCl acidic water solution. The highest percentage of depicts the positive result. In addition to that the SEM, wear, hardness tests are carried out to bring out the positive impact of the newly prepared samples. In accordance with that the fundamental spotlight is given on Aluminum network composites on account of its novel blend of good corrosion protection, wear properties and outstanding mechanical properties.

摘要 本研究以A6061铝合金为基体，添加4%与5%占比的石墨、氧化铝、碳化硅及碳化硼作为增强相，采用搅拌铸造法制备金属基混杂复合材料（Metal Matrix hybrid composite, MMHC）。采用3.5%氯化钠溶液浸泡试验与1%盐酸酸性水溶液浸泡试验，对未处理的A6061基增强复合材料试样的腐蚀性能进行评估。其中较高的增强相添加比例可获得更优的试验结果。此外，本研究还开展了扫描电镜（SEM）、磨损试验与硬度试验，以验证新型制备试样的性能优势。鉴于铝基复合材料兼具优异的耐蚀性、耐磨性能与突出的力学性能，具备独特的性能组合，本研究将核心研究焦点聚焦于该类材料。
