The problem statement highlights the lack of comprehensive understanding regarding the corrosion mechanisms of AHSS in aggressive environments, motivating the need for this research. The objectives of the study are to investigate the corrosion behavior of AHSS, identify the factors influencing their corrosion resistance, and propose mitigation strategies. The study is limited to laboratory-based experiments simulating aggressive environments commonly encountered in industrial settings. The scope includes a detailed analysis of the corrosion mechanisms, surface characterization techniques, and evaluation of protective coatings for AHSS. The significance of this study lies in its potential to enhance the durability and performance of AHSS components in aggressive environments, thereby reducing maintenance costs and improving operational efficiency. The structure of the thesis is divided into five chapters. Chapter One provides an overview of the research, including the introduction, background, problem statement, objectives, limitations, scope, significance, and definition of terms. Chapter Two presents a comprehensive literature review encompassing ten key areas related to corrosion behavior, advanced high-strength steels, aggressive environments, and corrosion mitigation techniques. Chapter Three outlines the research methodology, including experimental design, sample preparation, corrosion testing procedures, surface analysis techniques, data collection, and statistical analysis. The chapter also details the selection criteria for the test environments and the rationale behind the chosen methodologies. Chapter Four presents a detailed discussion of the research findings, including the corrosion behavior of AHSS in aggressive environments, the influence of alloy composition on corrosion resistance, the effectiveness of protective coatings, and the mechanisms of corrosion inhibition. The chapter also compares the experimental results with existing literature and discusses the implications for industrial applications. Chapter Five offers a comprehensive conclusion and summary of the thesis, highlighting the key findings, implications for the industry, and recommendations for future research. The conclusion emphasizes the importance of understanding the corrosion behavior of AHSS in aggressive environments and underscores the significance of implementing effective corrosion mitigation strategies to enhance the longevity and performance of AHSS components. In conclusion, this thesis provides a valuable contribution to the field of materials engineering by elucidating the corrosion behavior of advanced high-strength steels in aggressive environments. The insights gained from this study can inform the development of effective corrosion protection strategies and optimize the performance of AHSS components in industrial applications, ultimately advancing the sustainability and efficiency of engineering systems.
