A Review on Improving the Corrosion Resistance of 316L Stainless Steel by Coating with Nanoparticles of Chitosan/Gelatin Using Electrophoretic Deposition Method

Today, nanostructured coatings are highly regarded as one of the most widely used areas of nanotechnology.</em> Destructive factors like friction, wear, and environmental conditions in instruments and parts of the medical industry cause surface destruction. Therefore, to solve this challenge, researchers have reduced the percentage of component destruction by using surface engineering and applying nanocoatings. Orthopedic and dental implants are increasingly used in the medical field because of their high success rates. Implant-associated infections, however, still occur and are difficult to treat. Using an active coating on the implant surface is recommended to prohibit infection in medical parts. This review article mentions the types of medical materials used, especially the properties of 316L stainless steel alloy and the improvement of its corrosion resistance properties by coating with chitosan and gelatin nanoparticles by the electrophoretic method. Also, the effect of nanoparticles has been investigated. It was observed that the addition of nanomaterials reduces the amount of deposition, but due to the increase in surface quality and the reduction of porosity in the coating, it increases the corrosion resistance</em>.</em>
