Thesis Overview

The project titled "Development of High-Temperature Corrosion-Resistant Coatings for Gas Turbine Components" aims to address the critical issue of corrosion in gas turbine components operating at elevated temperatures. Gas turbines are widely used in power generation, aviation, and various industrial applications due to their high efficiency and power output. However, the harsh operating conditions, especially at high temperatures, expose turbine components to corrosion, leading to degradation and reduced performance over time. To combat this challenge, the research focuses on developing advanced corrosion-resistant coatings that can withstand high temperatures, aggressive environments, and mechanical stresses experienced in gas turbines. The study will investigate various coating materials, deposition techniques, and surface engineering approaches to enhance the durability and performance of gas turbine components exposed to corrosive conditions. The research overview will include a comprehensive literature review to understand the current state-of-the-art in high-temperature coatings, corrosion mechanisms in gas turbine environments, and the factors influencing coating performance under extreme conditions. By exploring existing research, the study aims to identify gaps in knowledge and opportunities for innovation in the field of high-temperature corrosion-resistant coatings. Furthermore, the project will detail the research methodology, including experimental design, sample preparation, coating deposition techniques, and corrosion testing procedures. The study will employ advanced analytical techniques such as scanning electron microscopy (SEM), X-ray diffraction (XRD), and corrosion testing methods to evaluate the microstructure, composition, and corrosion resistance of the developed coatings. The findings from this research are expected to contribute to the development of novel high-temperature corrosion-resistant coatings that can extend the service life, reliability, and efficiency of gas turbine components. The project outcomes have the potential to benefit industries reliant on gas turbines by reducing maintenance costs, downtime, and environmental impact associated with corrosion-related issues. In conclusion, the research on the "Development of High-Temperature Corrosion-Resistant Coatings for Gas Turbine Components" holds promise for advancing materials science, surface engineering, and industrial applications by addressing the critical need for durable and protective coatings in high-temperature environments. The innovative solutions generated from this study have the potential to revolutionize the performance and longevity of gas turbine components, contributing to enhanced efficiency, sustainability, and reliability in various sectors utilizing gas turbine technology.
