Characterization of phosphate conversion coating on mild steel for enhanced corrosion inhibition Mechanisms
This study focuses on the comprehensive characterization of phosphate conversion coatings applied to mild steel, emphasizing their role as inhibitive corrosion mechanisms. Through a multifaceted approach, including micro hardness testing, Spectromaxx Metal Analyzer analysis, and corrosion potentiostat testing, the research delves into the mechanical, chemical, and corrosion-resistant properties of the coated mild steel. Micro hardness testing reveals insights into the coating's impact on the material's resistance to indentation and deformation, providing a foundational understanding of its mechanical behavior. The Spectromaxx Metal Analyzer analysis elucidates variations in the chemical composition, specifically highlighting changes in alloying elements such as copper, which are crucial for corrosion resistance. Corrosion potentiostat testing further substantiates the inhibitive corrosion mechanism, showcasing reduced corrosion rates in various environments for the coated mild steel compared to the uncoated counterpart. The findings contribute to a nuanced comprehension of how phosphate conversion coatings enhance the material's durability and resilience in corrosive settings.
