Description
Summary:Arc-welding coatings are extensively employed within the informal sectors of many African countries to repair various machine components, such as gear teeth, machine shafts, bushings, and many others. In the pursuit of advancing steel component repair techniques, this study investigates the surface properties of mild steel plates coated with alumina using the Metal Inert Gas (MIG) welding process. Mild steel wire of diameter 1.6 mm, alumina particles of size 1 µm, and mild steel plates were used. The prepared samples were analysed for microstructural, hardness, wear, and corrosion properties. For the first time, and through a traditional welding process, it is demonstrated that the hardness, wear, and corrosion resistance of steel parts can be improved by the inclusion of alumina particles on their surfaces. As such, this work will have an impact on the informal engineering sector ( Jua Kali sector as known in Kenya) involved in the surface repair of steel components.
