This study explores the transformative role of High-Velocity Oxygen Fuel (HVOF) coatings in enhancing the performance of mechanical seals. Mechanical seals play a crucial role in various industrial applications, and their efficiency is often compromised by wear and corrosion. The utilization of HVOF coatings represents a cutting-edge approach to fortify these seals against deterioration, significantly extending their operational lifespan. The research aims to understand the causes of mechanical seal failure, specifically focusing on wear-related issues. Overall, the objective is to provide insights into the mechanisms and materials influencing mechanical seal failure. Through a comprehensive review of existing literature and recent advancements, this research elucidates the multifaceted benefits of HVOF coatings in mechanical seal applications. It delves into the mechanisms by which these coatings mitigate wear and corrosion, providing a protective shield against harsh operational conditions. This study contributes not only to the understanding of the advancements in HVOF coating technology for mechanical seals but also serves as a valuable resource for professionals seeking to optimize mechanical seal performance and extend their service life through innovative coating solutions.
