Corrosion protection refers to methods used to prevent or slow down the deterioration of materials, especially metals, due to chemical reactions with their environment. Common causes of corrosion include moisture, oxygen, and pollutants. Effective corrosion protection can extend the lifespan of structures and equipment, reducing maintenance costs. There are several techniques for corrosion protection, including the application of protective coatings, galvanization, and cathodic protection. Protective coatings, such as paint or varnish, create a barrier between the metal and corrosive elements. Galvanization involves coating metal with a layer of zinc, while cathodic protection uses electrical currents to counteract corrosion processes.
