Answers
Answer:
Corrosion is a natural process that converts a refined metal into a more chemically stable form such as oxide, hydroxide, or sulfide. It is the gradual destruction of materials by chemical and/or electrochemical reaction with their environment.
Methods
Metal Type. One simple way to prevent corrosion is to use a corrosion resistant metal such as aluminum or stainless steel. ...
Protective Coatings. The application of a paint coating is a cost-effective way of preventing corrosion. ...
Environmental Measures. ...
Sacrificial Coatings. ...
Corrosion Inhibitors. ...
Design Modification.
Galvanisation-Galvanisation or galvanization (or galvanizing as it is most commonly called) is the process of applying a protective zinc coating to iron or steel, to prevent rusting. The most common method is hot dip galvanizing, in which steel sections are submerged in a bath of molten zinc.
Answer:
Corrosion is a galvanic process that can be prevented using cathodic protection. The deterioration of metals through oxidation is a galvanic process called corrosion. ... Alternatively, a more easily oxidized metal can be applied to a metal surface, thus providing cathodic protection of the surface.
