Abstract

Microbiologically influenced corrosion (MIC) is acknowledged as a significant type of corrosion due to its extensive impact on metal/alloy surfaces. As MIC accounts for 20% of all corrosion instances, it is a critical factor causing service failure of engineering materials such as steel and aluminium alloy. Despite widespread use of aluminium's inherent properties, several aluminium alloys are prone to MIC due to microbial biofilm formation and metabolic activities at the biofilm/metal interface. This review comprehensively explores MIC over multiple series of aluminium alloys, highlighting their properties and vulnerabilities to MIC. It delves into the correlation between the aluminium alloy and microorganisms, offering an in-depth analysis of MIC mechanisms. It also explores the relationship between the composition of aluminium alloys and bacterial activity, highlighting their primary metabolic reactions that contribute to the corrosion of aluminium alloys. Additionally, the review depicts the impact of various environmental factors contributing to the deterioration of these alloys, and an extensive overview of MIC identification and characterization techniques on multiple metal/alloy types associated with the specific challenges and limitations, and outlines potential future directions regarding MIC. This review aspires to provide effective strategies for the detection and mitigation of corrosion-related obstacles. In conclusion, MIC poses significant risks to aluminium alloys in critical sectors. Effective detection and mitigation strategies are essential in improving material longevity and performance. Addressing MIC challenges proactively can help to ensure the reliability and durability of aluminium alloys in demanding environments. © 2025 The Author(s).
