dc.description.abstractThe steam turbine is the most effective and straightforward method of converting thermal energy into mechanical power. As steam expands, its velocity increases, exerting strong stresses on the turbine blades. The linear motion of the incoming steam with high temp and pressure is converted to rotation of the turbine shaft by the turbine blades. The most important issue in power plants might be corrosion in the turbine blades. Corrosion might cause turbine blade masses to be out of balance, which can cause major vibration issues. The ANSYS software program did a numerical analysis to investigate the impact of coating thickness for the selected coating materials (Ti, TiO2, and SiO2) on the steam turbine. The numerical analysis was done using six coating groups; three of them consist of single materials (Ti, TiO2, and SiO2), and the other three consist of hybrid coating (Ti+ TiO2, Ti+ SiO2, and Ti+TiO2+SiO2) and each group has three coating thickness (0.01, 0.02 and 0.04) μm. Numerical analysis results indicated that the total heat flux and the temp increased after applying the coating. In contrast, total deformation for all selected groups was decreased after applying a coating for all of them; the change in the coating thickness from (0.01 to 0.04) μm has no effective changes on the samples after coating. Using (Ti and TiO2) show a significant increase in max principal stress compared to the uncoated sample. The application of Ti shows the impact of coating thickness on max principal stress, where a change in the coating thickness from 0.01 to 0.04 μm leads to a reduction in the max principal stress value from 1421.9 to 1211.4 MPa.en_US
