Thesis Overview

The project titled "Development of High-Temperature Corrosion-Resistant Coatings for Cutting Tools" aims to address the critical need for improving the durability and performance of cutting tools exposed to high-temperature environments. In industries such as aerospace, automotive, and manufacturing, cutting tools are subjected to extreme temperatures, aggressive chemical environments, and high levels of mechanical stress during operation. These harsh conditions often lead to rapid degradation of the cutting tools, resulting in reduced tool life, increased maintenance costs, and decreased overall productivity. The primary objective of this research is to develop advanced corrosion-resistant coatings that can withstand high temperatures and aggressive environments, thereby enhancing the performance and longevity of cutting tools. The study will involve a comprehensive investigation of various coating materials, deposition techniques, and surface modification methods to identify the most suitable combination for achieving superior corrosion resistance and thermal stability. The research will begin with a detailed literature review to provide a thorough understanding of existing coating technologies, corrosion mechanisms, and materials used in cutting tool applications. This review will serve as the foundation for selecting the most promising coating materials and techniques for further investigation. The experimental work will focus on the synthesis and characterization of novel corrosion-resistant coatings using advanced deposition methods such as physical vapor deposition (PVD), chemical vapor deposition (CVD), and thermal spray techniques. The coatings will be evaluated for their microstructural properties, chemical composition, hardness, adhesion strength, and corrosion resistance under high-temperature conditions. In addition to developing the coatings, the research will also involve conducting performance tests on coated cutting tools to assess their wear resistance, cutting efficiency, and overall tool life compared to uncoated tools. The findings from these tests will be used to validate the effectiveness of the developed coatings in real-world cutting applications and provide insights into their potential industrial impact. Overall, this research seeks to contribute to the advancement of materials and metallurgical engineering by providing innovative solutions for enhancing the durability and performance of cutting tools operating in high-temperature and corrosive environments. By developing high-temperature corrosion-resistant coatings, this project aims to address the challenges faced by industries reliant on cutting tools, ultimately leading to improved productivity, cost savings, and sustainable manufacturing practices.
