Project Overview

The project titled "Development of High-Temperature Corrosion Resistant Coatings for Super Alloy Components in Gas Turbines" focuses on addressing a critical challenge faced in the field of Materials and Metallurgical Engineering. Gas turbines are essential components in power generation, aviation, and other industrial applications where high temperatures and harsh operating conditions are common. Super alloy components used in gas turbines are subjected to extreme temperatures, aggressive environments, and high mechanical stresses during operation. One of the primary issues faced by these components is corrosion, which can significantly reduce their performance, efficiency, and lifespan. To combat corrosion and enhance the durability of super alloy components in gas turbines, the project aims to develop high-temperature corrosion-resistant coatings. These coatings will act as a protective barrier, preventing the degradation of the underlying super alloy material and ensuring the long-term reliability of gas turbine components. By developing coatings that are specifically tailored to withstand the harsh operating conditions of gas turbines, the project seeks to improve the overall performance and efficiency of these critical systems. The research will involve a comprehensive investigation into the properties of super alloys, corrosion mechanisms at high temperatures, and the development of advanced coating materials. Various coating deposition techniques, such as physical vapor deposition (PVD) and chemical vapor deposition (CVD), will be explored to optimize the coating performance and durability. The project will also involve testing the coated samples under simulated gas turbine operating conditions to evaluate their corrosion resistance, mechanical properties, and overall effectiveness in protecting the underlying super alloy components. Through this research, the project aims to contribute to the advancement of materials engineering by developing innovative solutions to combat corrosion in high-temperature environments. The successful development of high-temperature corrosion-resistant coatings for super alloy components in gas turbines has the potential to significantly enhance the reliability, efficiency, and lifespan of these critical systems. Ultimately, the outcomes of this project may have broader implications for the aerospace, power generation, and other industries that rely on gas turbine technology for their operations.
