摘要：

This research work focuses on the experimental and theoretical analysis of the exhaust manifold with novel ceramic coatings (TiO2 Coatings; ZrO2 coatings; and Al2O3 coatings) and these coatings were applied on the manifold by the plasma arc technique with a temperature range of 14,000 & omicron;C and micron coatings ranging from 350 to 400 & mu;. The implementation of these coatings over the exhaust manifold gives enormous benefits such as improvised endurance strength, higher heat dissipation, and flexible directional heat flux compared to uncoated materials. From the numerical analysis, it is found that the ceramic coatings give lower thermal residual stresses compared to the uncoated materials. Among the three coatings, Al2O3 coatings give optimal performance in terms of heat dissipation, heat flux, and directional heat flux and also lower thermal residual stresses. From the overall analysis; it is also clear that the implementation of ceramic coatings on the exhaust manifold gives enormous advantages in terms of corrosion resistance and lesser maintenance as compared to uncoated materials.
