Development and Characterization of Silicon Nitride and Synthesized Graphene Oxide Reinforced Cu/GO/xSi3N4 Composites
The intent of the proposed research is to analyze the effect of Silicon Nitride (Si3N4) and synthesized Graphene Oxide (GO) on the physical, wear and corrosive characteristics of the copper. The copper hybrid composite having constant GO and varying weight % of Si3N4 is prepared through powder metallurgy. The GO is synthesized from graphite through modified hummers method and its formation is confirmed through SEM, XRD, Raman and FTIR analysis. The SEM analysis of developed Cu/0.3rGO/xSi3N4 confirms the presence of reinforcements and density analysis confirms the reduction density. The microhardness is found increasing with GO and Si3N4 addition. Wear rate of the copper found decreases with reinforcement addition due to self-lubricating nature of GO and hardness of Si3N4 ceramic. Worn surface confirms the transition of severe wear to mild wear with Si3N4 addition. The corrosion results suggest that the composite reinforced with 0.3% GO and 15% Si3N4 yielded better corrosion resistance than the other developed composites. Corroded surface analysis confirms the reduction in surface damage with reinforcement addition that shows increase in corrosion resistance of copper with hybrid reinforcement addition.
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.
