Corrosion is a process by which a chemical reaction eats away at a metal. An example of a chemical reaction that causes corrosion is the oxidation of iron by water in an electrolytic process. The product of this reaction is rust.
Causes of corrosion vary but are commonly attributed to primary and secondary water characteristics, physical water characteristics and bacteria. Other factors besides water characteristics and bacteria can cause corrosion too. Quality and age of metal pipes and the presence of electrical currents a
Corrosion leads to the degradation and weakening of the affected material. It is caused by materials reacting with the surrounding elements, such as oxygen or water.
As of 2015, the world's most corrosive acid is fluoroantimonic acid, according to About.com. This acid is the product of mixing hydrogen fluoride and antimony pentafluoride in equal ratios. Fluoroantimonic is 20 quintillion times stronger than sulfuric acid.
Corrosion science is the study of material degradation, both metallic and non-metallic. It is a branch of engineering and materials science, although it often spans other disciplines, with the goal being to understand and prevent corrosion.
An aluminum wheel cleaner and bristled brush can remove the corrosion on aluminum wheels. Once the corrosion is removed, the wheels requires frequent cleaning to prevent further buildup.
Overfilling the battery, poor design of the vent cap, age and distortion of the gaskets can all cause battery terminal corrosion. Nitrogen gas is emitted by the electrolyte in the battery. Material in the battery terminals and cable ends reacts with the nitrogen gas, and corrosion begins to form.
To remove corrosion from copper pipes, inspect the water's pH levels, and identify the source of corrosion. Remove the source of corrosion and install a calcite neutralizing filter to raise pH levels. Install a phosphate feeder to coat the piping with phosphate and reduce corrosion.
To clean alkaline battery corrosion, moisten it with a weak acid, rub it with a cotton swab, and scrape away the residue. The supplies you need include newsprint, white vinegar, cotton swabs and safety gear.
You can remove rust and corrosion from stainless steel by scouring it off, using an acidic solution, utilizing alkaline paste or employing commercial rust removal chemicals. Your choice depends on the extent of corrosion and ease of rust removal.
