Since bone is under the dynamic loading, using the metallic biomaterials are the best choice for their high enduring in tensional stressed. Although, AISI 316L stainless steel as metallic implant is a famous choice, this steel contains some defects such as releasing the harmful ions and lack of bioactive properties. Polymer-ceramic composite coating use on this implant in order to resolve the mentioned problems. Ceramics are the most suitable for coating, replacing or reminding the hard and soft tissue of human body because of their biocompatible and sufficient bioactive properties. In recent years, bioglass has received significant attention due to its bioactive properties. Polycaprolactone is a hydrophobic semi crystal and due to its extraordinary mechanical and bioactive properties has many usages in medical. However, the polymer has not used widely due to its expensive price and was finite in recent years. Also, chitosan has received significant attention due to its antibacterial, bio degradable, accessible and economical properties for researchers in medical usage. Despite these unique advantages, using chitosan have some problems such as unfavorable mechanical and chemical properties, low weight and high shrinkage. Aim of this study is using polycaprolactone-chitosan-bioglass composite coating on AISI 316L stainless steel to improve the base metal properties by electrophoretic method.
