Abstract

Polytetrafluoroethylene (PTFE) has emerged as a highly effective material for enhancing the durability and performance of metal surfaces, particularly in environments requiring superior corrosion resistance and low friction. This study investigates the application of PTFE coatings on various metallic substrates, with a focus on stainless steel and carbon steel, to improve their corrosion resistance, wear protection, and tribological performance. Utilizing advanced deposition techniques such as sol-gel and plasma spray, PTFE was applied to metal surfaces, forming a robust barrier against corrosive environments. The study also explores the integration of titanium dioxide (TiO2) nanoparticles into PTFE coatings, creating a nanocomposite that enhances the antibacterial properties of stainless steel implants. Corrosion tests in 40% HCl revealed significant improvements in corrosion resistance, with PTFE-coated metals demonstrating reduced current density and enhanced surface integrity. Additionally, tribological tests showed a considerable reduction in friction coefficients, particularly in components such as bearings and spherical joints. Molecular dynamics simulations further elucidate the role of helix reversal defects in PTFE’s phase behavior, contributing to its mechanical stability at elevated temperatures. The findings suggest that PTFE coatings, particularly when combined with TiO2, offer a promising solution for extending the lifespan of metallic components in harsh industrial and biomedical environments. This research presents a pathway for optimizing PTFE-based coatings for metallurgical applications, contributing to advancements in surface engineering technologies.

Keywords: Polytetrafluoroethylene (PTFE), corrosion resistance, tribological performance, nanocomposites, surface engineering
