Fabrication of nanostructured bioceramic coatings on 316l ss for orthopaedic applications

Abstract

Biomaterials are nonviable or any substance that has been engineered to interact with biological systems for a medical purpose to improve human health either a therapeutic treat augment repair or replace a tissue function of the body or a diagnostic one Biomaterials can be a natural or synthetic inorganic or organic material that extends the functionality of essential body parts beyond their life span In biomedical applications a biomaterial is expected to function in a safe and reliable manner in the tissue environment and should be nonimmunogenic and chemically inert to avoid undesirable effects on physiological body Further a biomaterial should be nontoxic and perform appropriate host response for specific application Hence orthopedic biomaterials are designed to be implanted in the human body as constituents of devices that are meant to perform certain biological functions by repairing or substituting different tissues such as bone cartilage or ligaments and tendons and or even guiding bone repair when necessary The selection of orthopedic implants from metallic materials shouldbe based on material properties such as mechanical strength corrosion resistance and biocompatibility thereby ensuring a long service with negligible failure 316L SS is a traditional medical metallic implant material highly used in medical devices such as coronarycardiovascular stents dental implants and cranial fixations for repairing bone deformities 316L SS is most preferred material because of its favorable combination of mechanical properties corrosion resistance ease of fabrication and satisfactory biocompatibility and relatively low cost compared to other orthopedic implants. newline
