Corrosion Resistance in Modern Metallurgical Alloys: Mechanisms & Mitigation Strategies
Abstract
Corrosion resistance in metallurgical alloys is a critical factor in their application across various industries, including aerospace, automotive, marine, and construction. This paper delves into the fundamental mechanisms of corrosion, such as galvanic, pitting, crevice, intergranular, and stress corrosion cracking, which significantly affect the longevity and reliability of alloys. It explores the intrinsic and extrinsic factors influencing corrosion behavior, including alloy composition, microstructure, environmental conditions, and mechanical stresses. Advancements in alloy design, such as the development of high-entropy alloys (HEAs), superalloys, and coatings, are examined for their enhanced corrosion resistance properties. The paper also reviews state-of-the-art mitigation strategies, including surface treatments, cathodic protection, and the use of corrosion inhibitors. Emphasis is placed on innovative approaches like nanotechnology, additive manufacturing, and environmentally friendly corrosion prevention methods. By synthesizing current research and technological developments, this paper aims to provide a comprehensive understanding of the mechanisms driving corrosion in modern alloys and to highlight effective strategies for mitigating these effects. The insights garnered from this study are intended to inform future alloy development and corrosion management practices, ultimately contributing to the sustainability and efficiency of industrial applications.
