Tin coatings on low carbon steel are extensively used in the food industry in tin cans. Describe how tin coating solves the corrosion of the base metal (which is low carbon steel) \ a can.

Paint coating is widely used as a prevention method of corrosion. In paint coating systems, primer is the most important component. State the functions of primers.

Corrosion can be prevented by selecting a good design. Sketch a good and a bad design for each of the following to avoid erosion corrosion. i. Drainage system ii. Piping system
