Abstract

The analysis of vibration over coated sample is required to investigate the vibration and noise damping behaviors of coatings. In this research work, conventional gun spray method is used to coat oxime modified titanium (IV) isopropoxide on steel to find out damping behaviour of coating. The most conventional method modal analysis is used to measure vibration and noise damping of bare and titania coated samples. During vibration test it was observed that a thin coating has improved the vibration and noise damping when compare with bare sample. The surface morphology of coated samples analysis by Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Analysis (EDX) and Atomic Force Microscopy (AFM) revealed that the coating thickness and composition of coating. The results shows that the modified TiO2 coating deposited over steel alloy by gun spry method is uniform, homogenous, crack free, and having high vibration damping behavior.
