Thesis Overview

The project titled "Development of High-Temperature Oxidation Resistant Coatings for Metallic Alloys" focuses on addressing the critical challenge of oxidation in metallic alloys when exposed to high-temperature environments. Oxidation is a common phenomenon that can lead to degradation and failure of metallic components, particularly in industries such as aerospace, power generation, and automotive. Developing effective coatings that can resist oxidation at elevated temperatures is essential to enhance the durability and performance of metallic alloys in such applications. The research will begin with a comprehensive literature review to understand the existing knowledge and technologies related to high-temperature oxidation resistance coatings for metallic alloys. This review will cover various types of coatings, their mechanisms of protection, and their applications in different industries. By analyzing the current state-of-the-art in this field, the research aims to identify gaps and opportunities for further improvement. The methodology of the research will involve experimental investigations to develop and test novel high-temperature oxidation resistant coatings for metallic alloys. Various deposition techniques such as physical vapor deposition (PVD), chemical vapor deposition (CVD), and thermal spray will be explored to apply the coatings on different alloy substrates. The performance of these coatings will be evaluated through oxidation tests at elevated temperatures to assess their effectiveness in preventing oxidation and improving the longevity of the metallic components. The findings of the research will provide insights into the effectiveness of different coating materials and deposition techniques in enhancing the oxidation resistance of metallic alloys at high temperatures. The discussion will delve into the mechanisms of oxidation protection offered by the coatings, the microstructural changes in the alloys after exposure to high temperatures, and the potential applications of the developed coatings in industrial settings. The significance of this research lies in its potential to advance the field of materials engineering by offering innovative solutions to combat oxidation in metallic alloys. By developing high-temperature oxidation resistant coatings, this project aims to contribute to the improvement of component lifespan, energy efficiency, and overall performance in critical industries where oxidation is a prevalent issue. In conclusion, the project on the "Development of High-Temperature Oxidation Resistant Coatings for Metallic Alloys" seeks to address a pressing engineering challenge by proposing novel coatings that can protect metallic alloys from oxidation at elevated temperatures. Through systematic research and experimentation, this project endeavors to make a valuable contribution to the development of advanced materials with enhanced durability and reliability in high-temperature environments.
