The goal of this study is to develop a procedure for measuring the vibration characteristics of rotating blades, which will eventually be utilized to monitor the structural health of these structures. Turbocharger was failing because of the high pressure and rotational speed, so that to examine the stress placed on the turbocharger’s turbine blade, specifically in relation to the (118 KW) engine used in automobiles. The rate of volume flow of this turbine was run at (10000 r.p.m). SolidWork software was employed in study and modeling of the turbine blade of turbo engine, and suitable finite element model was produced. The turbocharger turbine wheel with (8, 10 and 12) blades had designing and optimizing the materials for it in this work.
The Dissertation included recommendations including:
- To ensure high hardness, the Pulsed laser deposition was used for the turbocharger blade to deposit a layer of a nanomaterial (Alfa- Al2O3) (10 μm) on the surface of the aluminum alloy.
- Using a layer of nano to reduce corrosion, erosion and roughness.
- Increasing the number of blades to increase the natural frequency as the number of blades increased the frequency, especially for the turbine wheel with (12) blades.
After the scientific discussion by the members of the discussion committee, the researcher received a rating of (Very good).
