[ Principles of Corrosion ]

Corrosion, like maths, doesn’t depend on an opinion.  Corrosion (also known as rust) just needs electrochemistry (science) to explain that otherwise mysterious reaction in metals. 

There are factors that affect corrosion, such as acidity, oxidising agents, temperature, and electrolyte velocity.

There are different types of corrosion: intergranular corrosion, pitting, galvanic, crevice, and that old chestnut, stress-corrosion cracking.

There are a few ways to prevent corrosion – many are a variation of a theme: coatings or cathodic protection.

Rust is just science; no opinion required.  But, determining the best solution to prevent it? Now there’s an opinion-based black box to be deciphered.
