what sustains the resistance?
The RMS Titanic has spent more than a century on the bottom of the Atlantic. But why is part of its iron wreck passing the test of time while the rest gives way to serious corrosion?

When iron comes into contact with water, rust is an inevitable electrochemical reaction. The salt present in ocean water only speeds the process of oxidation, claiming some of the world's most iconic shipwrecks.

The lack of oxygen in the deep sea helps to slow corrosion, such as rust. But to preserve wrecks for future study, scientists suggest that underwater robotic application of corrosion-resistant antifouling paints could also help.
The lower half of Titanic's hull, coated in antifouling paint in 1912, is still largely intact, and in much better condition than its uncoated sections.

CORROSION-RESISTANT ALUMINUM

ACDelco GM OE A/C Condensers aren't protected with antifouling paint like a ship. But they are made from aluminum, which can resist corrosion naturally. Because when aluminum oxidizes, it forms an outer layer that naturally protects the underlying metal from corroding further.
