Abstract

Magnesium and its alloys have many applications in industry, domestic purposes, and also in the biological field, mainly in implantation because of its excellent physical and mechanical properties. Due to its high strength to weight ratio, it is widely used in many industries and transport. But on exposure to unescapable severe service conditions like salt spray, Magnesium, and its alloys are highly susceptible to destruction. These led to the minimum use in the automotive and aerospace industries. The easiest way to avoid destruction is to change the nature of the surrounding by adding inhibitors. This paper detail state of art in the closing of active centers on Magnesium AZ31B alloy by gelatin molecules. The prevention efficiency was measuredby electrochemical techniques, and surface modification studies were done by scanning Electron microscope (SEM), energy dispersive X-ray (EDX), and atomic force microscope (AFM). The effects of temperature and gelatin concentration in HCl on AZ31B Magnesium alloy werestudied using response surface methodology (RSM) with a central composite design. RSM was used to optimize the prevention efficiency of gelatin on AZ31B Magnesium alloy and to estimate the effects and the interactions of temperature and gelatin concentration on %I.E. The highest prevention efficiency was found to be 86% at 303 K and 2.5 mM gelatin concentration.
