Thesis Overview

The project titled "Development of High-Temperature Corrosion Resistant Coatings for Gas Turbine Engine Components" aims to address the critical need for advanced protective coatings for gas turbine engine components operating at high temperatures. Gas turbines are crucial components in power generation, aviation, and other industrial applications, where they are subjected to extreme temperatures and harsh operating conditions. The continuous exposure to high temperatures, aggressive combustion environments, and corrosive gases can lead to degradation and failure of turbine components, resulting in costly maintenance and downtime. The research focuses on developing innovative coatings that can provide enhanced corrosion resistance and thermal protection to gas turbine components, thereby extending their service life and improving overall performance. By employing advanced materials and coating technologies, the project seeks to mitigate the detrimental effects of high-temperature corrosion and oxidation, as well as other forms of degradation such as erosion and wear. Key aspects of the research include investigating the properties and performance of different coating materials, such as ceramics, thermal barrier coatings, and specialized alloys, under high-temperature conditions. The project will involve experimental studies to assess the corrosion resistance, thermal stability, adhesion strength, and other relevant properties of the developed coatings. Additionally, the research will explore various coating deposition techniques, including thermal spray, physical vapor deposition, and chemical vapor deposition, to optimize the coating process and ensure uniform coverage on complex turbine components. Furthermore, the project will address the challenges associated with the application of high-temperature coatings on intricate geometries and critical areas of gas turbine components, such as turbine blades, combustors, and casings. By developing tailored coating solutions that are compatible with the specific operating conditions of gas turbines, the research aims to enhance the reliability, efficiency, and durability of these components in demanding environments. Overall, the research overview highlights the significance of developing high-temperature corrosion resistant coatings for gas turbine engine components to meet the increasing demands for advanced materials in the aerospace, energy, and industrial sectors. The outcomes of this project are expected to contribute to the advancement of coating technologies for high-temperature applications, leading to improved performance, reduced maintenance costs, and extended service life of gas turbine systems."
