摘要：

This analysis is concerned with the investigation of the capability of alumina coating deposited by spray coating method using oxime-modified aluminum(III) isopropoxide as a sol-gel precursor to improve vibration damping and anti-corrosion properties of aluminum alloys. Coating microstructures, thickness and roughness were investigated by scanning electron microscopy (SEM) and atomic force microscopy (AFM) studies, respectively. To this end, the quality of the coating was determined by the corrosion rate which was analyzed by mean of electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization. The vibration and noise technique were applied to measure comparison of vibration and noise damping of bare and alumina coated samples. The results indicate the alumina coating deposited over aluminum alloy by spray coating method is uniform, homogenous, crack free, having high vibration damping and anti-corrosive behavior.
