Understanding Oxidation on Wheels
Oxidation, commonly known as rust, is a natural process that affects many metals, including the aluminum and steel used in wheel construction. It’s a chemical reaction that occurs when metal comes into contact with oxygen and moisture, resulting in the formation of metal oxides. In the context of wheels, oxidation can lead to unsightly blemishes, corrosion, and even structural weakening.
Causes of Wheel Oxidation
Oxidation on wheels is primarily caused by exposure to various environmental factors.
- Exposure to Elements: Rain, snow, and humidity provide the moisture necessary for oxidation to occur. The sun’s ultraviolet (UV) rays can accelerate the process by breaking down the protective coatings on wheels.
- Road Salt: Used extensively in colder climates to melt ice and snow, road salt is highly corrosive. It can quickly penetrate protective coatings and accelerate the oxidation process.
- Brake Dust: The heat generated during braking causes the brake pads to shed microscopic particles of metal, known as brake dust. This dust can accumulate on the wheels, creating a corrosive environment that promotes oxidation.
Wheel Materials and Oxidation
The susceptibility of wheels to oxidation depends on the material used in their construction.
- Aluminum: Aluminum is a relatively corrosion-resistant metal, but it can still oxidize, especially when exposed to harsh environments. The oxide layer formed on aluminum is generally thin and protective, preventing further corrosion.
- Steel: Steel is more susceptible to oxidation than aluminum. When exposed to moisture, steel can rust quickly, forming a reddish-brown oxide layer. This layer is not protective and can lead to further corrosion if not addressed.
- Chrome: Chrome-plated wheels are highly resistant to oxidation. The chrome plating acts as a barrier, preventing moisture and oxygen from reaching the underlying metal. However, scratches or chips in the chrome plating can expose the metal to corrosion.
