Thesis Overview

The research project "Investigating the Corrosion Resistance of Additively Manufactured Metal Alloys" aims to address the growing interest in utilizing additive manufacturing techniques for producing metal components in various industries. Additive manufacturing, also known as 3D printing, offers unique advantages such as design flexibility, reduced material waste, and the ability to create complex geometries. However, one critical aspect that needs to be thoroughly evaluated is the corrosion resistance of metal alloys produced using additive manufacturing methods. Corrosion is a significant concern in many applications where metal components are exposed to harsh environments, such as marine, aerospace, and automotive industries. The corrosion resistance of a material determines its durability, reliability, and maintenance requirements over its operational lifespan. Therefore, understanding how additive manufacturing affects the corrosion resistance of metal alloys is crucial for ensuring the structural integrity and performance of manufactured components. This research project will focus on investigating the corrosion behavior of metal alloys fabricated using additive manufacturing techniques. The study will involve the selection of specific metal alloys commonly used in industrial applications and the manufacturing of test specimens using additive manufacturing processes, such as selective laser melting (SLM) or electron beam melting (EBM). These specimens will then be subjected to various corrosion tests to evaluate their resistance to different corrosive environments. The research will also explore the influence of key factors, such as processing parameters, powder characteristics, and post-processing treatments, on the corrosion resistance of additively manufactured metal alloys. By systematically analyzing these factors, the project aims to provide insights into how different manufacturing variables impact the corrosion performance of metal components. Furthermore, the research overview will include a comprehensive review of existing literature on corrosion resistance testing methods, additive manufacturing processes, and the corrosion behavior of metal alloys. By synthesizing this knowledge, the project seeks to identify gaps in the current understanding of how additive manufacturing affects the corrosion resistance of metal alloys and propose recommendations for future research directions. Overall, the research on investigating the corrosion resistance of additively manufactured metal alloys is essential for advancing the use of additive manufacturing in industries where corrosion plays a critical role in component performance and longevity. By bridging the gap between additive manufacturing technology and corrosion science, this project aims to contribute valuable insights that can inform material selection, design optimization, and process development for achieving enhanced corrosion-resistant metal components.
