Abstract
The study of the thermal, wear and corrosion properties of developed nanocomposite coatings of Zn-Al2O3 and Zn- Cr2O3 was carried out. The coatings were produced by electrodeposition technique from chloride acidic bath. Laboratory tube furnace was used for the thermal analysis. The wear test was performed using CETR tribo-tester dry reciprocating tester. The hardness properties were investigated using diamond base Dura microhardness tester. Scanning electron microscope (SEM) affixed with energy dispersive spectrometry was used to study the morphological characteristics, before and after wear deformation. The corrosion degradation behavior was observed using linear polarization technique in 3.5% NaCl. In all the interaction, the effects of the incorporated Al2O3 and Cr2O3nanoparticulates on zinc rich coatings were found to have an excellent influence on the wear, corrosion and thermal stability properties. The fabrication and properties exhibited by the alloys were therefore found to be satisfactory and shows good predictability and applicability
