Enhancement in Surface Properties of Magnesium Alloy after Electroless Ternary Alloy Nano Composite Coating
Abstract
AZ91 Magnesium alloys have exceptional rigidity, low density, and electromagnetic protection properties, making them ideal for usage in numerous industrial components. But Magnesium alloys specially AZ91 have a significant disadvantage in terms of corrosion and hardness, which restricts their practical uses. One of the most recent ways for improving the corrosion and hardness of Mg alloys is electro-less nano-coating. This study investigates the hardness and corrosion properties of AZ91 Magnesium Alloy as a result of ENi-B-TiO2 Nano composite coating processes. It would be useful to conduct a thorough examination, including experimental analysis, into the possibilities of increasing the deposit efficiency and characteristics of composite deposits by designing a suitable bath composition and operating circumstances. It has been discovered that as the concentration of titania particles increases, so does the surface hardness of coatings. The optimal concentration of second-phase (titania) particles and bath agitation are also examined in order to get superior surface properties following Nano coating. Following this nano coating, the materials may be employed for a variety of materials engineering applications. The influence of coating parameters on the surface characteristics of ENi-B-TiO2 composite coatings was investigated in this study.
