corrosion
Let an agent handle corrosion by mechanism, materials, environment, prevention and inspection, noting safety-critical cases.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent handle corrosion by mechanism, materials, environment, prevention and inspection, noting safety-critical cases.
The gradual degradation of materials, especially metals, by chemical or electrochemical reaction with their environment, such as rusting of iron, galvanic corrosion, pitting and stress corrosion cracking; controlled by coatings, alloys and cathodic protection.
What it is for: Protecting structures, vehicles, pipelines and equipment.
It can be identify corrosion types; choose prevention methods; plan inspection and maintenance; recognise safety-critical corrosion.
Distinguishing features
Chemical or electrochemical degradation
Environment-dependent
Costly and dangerous
Preventable with design
What it looks like
Rust, pits, discolouration, flaking or cracks on surfaces.
How it is recognised
Red-brown rust on steel
Green patina on copper
Erosion is mechanical wear, sometimes combined
