| Abstract: |
| Piston is one of the most important components of an engine. It facilitates the conversion of heat energy into useful mechanical work through its to and fro motion. During its to and fro movement, it is often subjected to various mechanical stresses and thermal load. Therefore, it is quite important to study these external factors acting on piston for its proper functions and prolonged life span. In this paper, structural analysis on conventional piston made up of AlSi alloy has been investigated. Secondly, analysis was performed on ceramic coated AlSi alloy piston material. The material used for ceramic coating are MgZrO3 (Magnesium zirconium oxide) and PYSZ (Partially Yttria Stabilized Zirconia). The design of piston was carried out in the Autodesk Fusion 360 software. The coating thickness is varying in nature and the analysis was performed using the ANSYS software. Finally, the results of conventional piston, MgZrO3 coated piston and PYSZ coated piston with varying layer thicknesses were found out and compared with one other. It has been found that the MgZrO3 coating material is better than PYSZ coating material as it has better fracture toughness, being harder than PYSZ material, better thermal and structural shock absorbing capability. |
