The process of pit nucleation is initiated by the depassivation of the protective oxide layer isolating the metal substrate from the aggressive solution. The depassivation of the protective oxide layer is the less properly understood step in pitting corrosion and its very local and random appearance probably its most enigmatic characteristic.

If rust is present on a body panel, the panel was damaged by a collision, or other damage is present, there are several options for repair: fix the damaged panel (minor damage), replacement (excessively damaged panels), or cutting out and replacing a portion of the panel (moderate damage—for many makes of vintage car, small partial patch ...
Corrosion is a natural process that converts a refined metal into a more chemically stable oxide.It is the gradual deterioration of materials (usually a metal) by chemical or electrochemical reaction with their environment.
There are aftermarket electronic "rustproofing" technologies claimed to prevent corrosion by "pushing" electrons into the car body, to limit the combination of oxygen and iron to form rust. The loss of electrons in paint is also claimed to be the cause of “paint oxidisation” and the electronic system is also supposed to protect the paint. [ 4 ]
Rust scale forming and flaking off from a steel bar heated to its forging temperature of 1200°C. Rapid oxidation occurs when heated steel is exposed to air. Rust is a general name for a complex of oxides and hydroxides of iron, [4] which occur when iron or some alloys that contain iron are exposed to oxygen and moisture for a long period of ...
Channel 2 Atlanta reports that affected car owners in New York have filed a class-action lawsuit in federal court against Hyundai to recover the costs of repairs to fix the peeling paint issue on ...
