Investigating Corrosion in Silicon Carbide Composites

In his research paper, "Investigating Corrosion in Silicon Carbide Composites," K Manoharan delves into the study of the effects of corrosion on silicon carbide composites. These composites are used in various industrial applications, such as aerospace, automobile, and marine industries, due to their exceptional durability and resistance to abrasion and wear. However, their mechanical properties can be degraded by exposure to corrosive environments, leading to environmental degradation and reducing their longevity.Manoharan examines the role of aluminum matrix particles in reinforcing the composites and how they affect the composite's resistance to corrosion. The study looks at various parameters that can influence the corrosion behavior of these composites, such as temperature, pH, concentration, humidity, and water chemistry. The study also examines the electrochemical processes that occur during corrosion, including surface analysis and corrosion rate measurements using SEM analysis.The research delves into the importance of protective coatings and layers in preventing corrosion, as well as the use of corrosion inhibitors in extending the life of the composite materials. The paper also discusses the various corrosion mechanisms that occur, such as pitting, crevice corrosion, and galvanic corrosion, and the role of passivation in preventing corrosion.Furthermore, the study examines the effects of accelerated testing on the corrosion behavior of silicon carbide composites, as well as the corrosion products that are formed during exposure to corrosive environments. The study also looks at oxidation and erosion processes and the role of surface treatment in preventing corrosion.The research concludes by discussing the importance of composite manufacturing processes in preventing corrosion and the need for adhering to corrosion standards in ensuring the longevity of these materials. Overall, K Manoharan's research sheds light on the mechanisms and prevention of corrosion in silicon carbide composites, contributing to the ongoing efforts in developing and maintaining durable composite materials.
