Corrosion :
⍟ Metals that are chemically active get corroded in the presence of air and moisture in the atmosphere. Metals with a higher reactivity (such as magnesium, aluminum, iron, zinc, and tin) are much more prone to corrosion.
⍟ Corrosion is a natural process, which converts a refined metal to a more chemically stable form, such as its oxide, hydroxide, or sulphide. It is the gradual destruction of materials (usually metals) by chemical and/or electrochemical reaction with their environment. Corrosion degrades the useful properties of materials and structures including strength, appearance, and permeability to liquids and gases.
⍟ Corrosion is the deterioration of a metal as a result of chemical reactions between it and the surrounding environment.
Ways to prevent corrosion :
✯ Keep the area around metal dry by using drying agents or moisture barrier products .
✯ Coating a metal surface with paint or enamel or plastic provides a barrier between the metal and the moisture in the environment.
✯ By connecting metal to a more electropositive metal (cathodic protection).
✯ By the processes of Galvanisation and electroplating.
