a reddish-brown coating that forms on iron or steel when exposed to oxygen and moisture

a maintenance worker points at thick reddish-brown flakes covering an old iron gate while explaining the damage to a younger apprentice. The worker scrapes off some of the crumbly reddish coating with a small tool to show the extent of corrosion. Years of ocean spray and rain have transformed the once-shiny metal surface into a rough, oxidized mess. The underlying metal appears weakened and pitted where the corrosion has eaten through. The apprentice nods while taking notes, surrounded by other rusted equipment showing similar deterioration. the reddish-brown coating that forms on iron or steel when exposed to oxygen and moisture
