Sacrificial Anodes: Part One

Sacrificial anodes are specifically designed to act as corrosion ‘decoys’ for materials which require protection from a variety of corrosive forces.
Typically with more negative electrochemical potential sacrificial anodes for steel can include zinc, aluminum and magnesium based on their position in the galvanic series.

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.

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.
