Abstract

Surface composites (SCs) of aluminium-magnesium (Al–Mg) alloys reinforced with nano and micro silicon carbide (SiC) particles were fabricated using friction stir processing (FSP). The SCs were fabricated by multi-pass (five passes) FSP using a H13 steel tool. An investigation of the microstructural evolution, mechanical properties, wear behaviour, and corrosion resistance was conducted. The study revealed that nano-SiC reinforced SCs outclassed the micro-SiC reinforced as well as base metal (BM) counterparts in all domains. The ultimate tensile strength (337 MPa) and yield strength (315 MPa) of nano-SiC reinforced were 25.2% and 26.5% higher than BM (269 MPa and 249 MPa) and 13.5% and 11.3% higher than micro-SiC reinforced SC (287 MPa and 263 MPa), respectively. The wear rate in nano-SiC reinforced SC reduced significantly by about 16.67%, 14.73%, and 14.43% compared to BM and by 4.76%, 7.4%, and 7.78% compared to micro-SiC reinforced SC at 15N, 20N, and 25N loads, respectively. The nano-SiC reinforced SC showed 60% better corrosion resistance compared to BM and 50% better than micro-SiC reinforced SC. These improvements in reinforced SCs are attributed to various reasons: grain refinement due to FSP, uniform distribution of hard ceramic particles within the Al matrix, and the reduction in wear and corrosion-prone sites due to multiple FSP passes that minimise the agglomeration of reinforcement particles. This enhancement in the properties of nano-SiC-reinforced Al–Mg SCs makes them suitable for various applications in marine, automobile, and aerospace engineering domains.

微纳米碳化硅增强铝5052表面复合材料搅拌摩擦加工的对比分析

采用搅拌摩擦法（FSP）制备了纳米和微碳化硅（SiC）增强铝镁（Al-Mg）合金表面复合材料。sc采用H13钢刀具，采用多道次（五道次）FSP制备。研究了合金的显微组织演变、力学性能、磨损性能和耐蚀性。研究表明，纳米sic增强SCs在所有领域都优于微sic增强和贱金属（BM）。纳米sic增强SC的极限抗拉强度（337 MPa）和屈服强度（315 MPa）分别比BM （269 MPa和249 MPa）高25.2%和26.5%，比微sic增强SC （287 MPa和263 MPa）高13.5%和11.3%。在15N、20N和25N载荷下，纳米sic增强SC的磨损率与BM相比分别显著降低了16.67%、14.73%和14.43%，与微sic增强SC相比分别降低了4.76%、7.4%和7.78%。与BM相比，纳米sic增强SC的耐腐蚀性提高了60%，比微sic增强SC提高了50%。增强SC的这些改进归功于各种原因：FSP使晶粒细化，Al基体内硬陶瓷颗粒分布均匀，以及由于多次FSP通道减少了增强颗粒的团聚，从而减少了磨损和腐蚀易发部位。纳米sic增强Al-Mg - SCs性能的增强使其适用于船舶、汽车和航空航天工程领域的各种应用。图形抽象

期刊介绍： The journal Silicon is intended to serve all those involved in studying the role of silicon as an enabling element in materials science. There are no restrictions on disciplinary boundaries provided the focus is on silicon-based materials or adds significantly to the understanding of such materials. Accordingly, such contributions are welcome in the areas of inorganic and organic chemistry, physics, biology, engineering, nanoscience, environmental science, electronics and optoelectronics, and modeling and theory. Relevant silicon-based materials include, but are not limited to, semiconductors, polymers, composites, ceramics, glasses, coatings, resins, composites, small molecules, and thin films.
