Abstract
Zn-Al2O3 composite coating electrodeposits have been produced from chloride bath in the presence of Triethanolamine (TEA) and Monoethanolamine (MEA). The plating effect of TEA and MEA as addition agent on the Zn-Al2O3 alloy is investigated using SEM/EDS, x-ray diffraction (XRD) and atomic force microscope (AFM). The mechanical properties were examined through micro-hardness tester. The presence of TEA and MEA as a surface-active additive is also felt to accompany the performance of the fabricated coating. The SEM results for Zn-Al2O3 deposits in the presence of TEA/MEA indicate that surface-active additive have a strong influence on the deposit surface morphology and improved micro-hardness behavior which is assisted by the change in the deposition process parameter.
