Effect of MgO/MnO 2 Additives on the Structural Properties of Zinc Electroplated Mild Steel

摘要

Low carbon steel is widely used in engineering applications due to its availability, physical properties and reasonable cost. Regardless of the massive use of mild steel in engineering applications, their application is limited to high tribology and corrosive environment are limited due to low corrosion resistance properties, low microhardness and poor tribological properties. The increase in service life and exceptional properties of reinforcement composite coatings for advanced engineering application has attracted many researchers world-wide. In this study, the effect of manganese oxide (MnO2) on Zn-MgO chloride bath coating by co-deposition route on mild steel is studied. The coating micrographs and surface thickness were examined by means of scanning electron microscope (SEM) coupled with energy dispersive spectroscopy (EDS) and PosiTector (SPG) respectively. The thermal stability of the synthesized composite coatings studied in isothermal furnace at 350°C. The findings of the studies are discussed in this paper.
