Smart Coatings for Corrosion Protection

Smart coatings provide a new approach to the important and established topic of protective coatings to protect metallic materials from external environmental influence such as corrosion.
Smart coatings go further by reacting and consequently performing in response to a range of external stimuli such as temperature, UV light, and pH changes.

Stress Corrosion Cracking of Aluminum Alloys

This comprehensive analysis examines stress corrosion cracking (SCC) in aluminum alloys, focusing on the mechanisms, susceptibility factors, and behavior across different alloy series. The study reveals that alloys 7079-T6, 7075-T6, and 2024-T3 account for over 90% of service failures in high-strength aluminum alloys.

Understanding Bimetallic Corrosion: Prevention and Protection in Metal Structures

Bimetallic corrosion represents a significant challenge in structural engineering, occurring when two dissimilar metals are joined together in the presence of an electrolyte. This electrochemical process results in preferential corrosion of the anodic metal, potentially compromising structural integrity. The corrosion rate depends on factors including the galvanic series positions of the metals, electrolyte conductivity, and environmental conditions.

Wet Corrosion

This article provides a comprehensive examination of wet corrosion, a fundamental type of material degradation that occurs through electron transfer in the presence of moisture. The text details the electrochemical mechanisms distinguishing wet corrosion from dry corrosion, exploring the complex interplay of oxidation and reduction processes.
