Pitting Corrosion: What It Is, Why It Matters for Surface Preparation, and How to Address It
Pitting corrosion is localised attack that forms small, deep cavities, usually driven by chlorides. It matters for surface preparation because pits hold...

Galvanic Corrosion: How It Works and the Role of Zinc-Rich Primers in Protection
Galvanic corrosion happens when two dissimilar metals are electrically connected in an electrolyte: the more active metal (the anode) corrodes faster and...

MIC Corrosion: What Microbiologically Influenced Corrosion Is and How Coatings Address It
Microbiologically influenced corrosion (MIC) is corrosion started or accelerated by microorganisms, mainly sulfate-reducing, acid-producing and iron-oxidising bacteria living in biofilms. It causes...

Stress Corrosion Cracking: What It Is, Where It Occurs, and How Coatings Prevent It
Stress corrosion cracking (SCC) is cracking caused by sustained tensile stress acting together with a specific corrosive environment on a susceptible material....
