Abstract: This paper explains the various types of coatings which include metals, polymers, aerogels and ceramics coatings applied on metal surfaces through different methods so as to prevent oxidation, corrosion, cracking, wear and increase surface temperature. Coatings are covering layers applied to metallic surfaces in engineering applications so as to improve performance. They serve as protection to the underlying material. Literatures had it that coating applied in automobile and stationary engines, gas turbines and other internal combustion engines has helped to increase their brake thermal efficiencies. This happened because of increased surface temperature achieved in the combustion chambers due to low thermal conductivity and matched coefficient of thermal expansion of the coating materials.
Keywords: Coatings, Performance, Brake Thermal Efficiency, Thermal Conductivity.
