Investigation of the Corrosion Behavior of Additively Manufactured Metal Alloys

Thesis Abstract

Abstract
This thesis investigates the corrosion behavior of additively manufactured metal alloys, focusing on understanding how the unique characteristics of additive manufacturing processes influence the corrosion resistance of metal components. Additive manufacturing, also known as 3D printing, has revolutionized the production of complex metal parts with tailored properties. However, the impact of additive manufacturing on the corrosion resistance of metal alloys is not yet fully understood. This research aims to address this gap by studying the corrosion behavior of additively manufactured metal alloys under different environmental conditions. The study begins with a comprehensive literature review to establish the current state of knowledge regarding corrosion mechanisms in metal alloys and the effects of additive manufacturing on material properties. The literature review covers key concepts such as electrochemical corrosion processes, factors influencing corrosion resistance, and the influence of microstructure on corrosion behavior. The research methodology section outlines the experimental approach employed to investigate the corrosion behavior of additively manufactured metal alloys. Various corrosion testing techniques, such as electrochemical impedance spectroscopy and potentiodynamic polarization, are utilized to evaluate the corrosion resistance of the samples. The effects of different environmental factors, such as pH, temperature, and chloride concentration, on the corrosion behavior of additively manufactured metal alloys are systematically analyzed. The results and discussion section presents the findings of the corrosion experiments and provides a detailed analysis of the corrosion behavior of the additively manufactured metal alloys. The microstructural characteristics of the samples are examined using scanning electron microscopy to correlate the material properties with the observed corrosion performance. The influence of process parameters, such as build orientation and post-processing treatments, on the corrosion resistance of additively manufactured metal alloys is also investigated. The conclusion summarizes the key findings of the study and highlights the implications for the design and application of additively manufactured metal components in corrosive environments. The research contributes to the understanding of how additive manufacturing processes affect the corrosion behavior of metal alloys and provides insights into strategies for enhancing the corrosion resistance of additively manufactured components. Overall, this thesis provides a comprehensive analysis of the corrosion behavior of additively manufactured metal alloys and offers valuable insights for researchers and industry professionals seeking to optimize the performance of metal components produced using additive manufacturing technologies.
