Description
The influence of TiO2 composite and dispersed pure Al particle on zinc alloy electrodeposited on mild
steel was studied from chloride bath solution.Microstructural and mechanical properties of the alloy were
investigated. The structure, surface morphology, and surface topography of the deposited alloys were
characterized by scanning electron microscopy (SEM) and atomic force microscope (AFM).In addition,
hardness of the coated alloys was measured. It was found that the obtained Zn-Al-TiO2 alloyexhibited
more preferred surface morphology and mechanical strength compared tothe substrate. The result shows
the existence of interaction between TiO2 compounds and zinc alloy particulate. It also exhibited well
bright dominate zinc coating on steel surface.
