The current era is characterised by a worldwide continuous enhancement in the average of males and females, which has led to the rapidly increasing demand for biomedical implants. As per the current analysis in India, approximately seven crore people are suffering from joint related issues, and this incidence rate is expected to rise. In addition, the global sale of medical devices (orthopedic implants) in 2003 alone was USD 8.7 billion and is projected to develop at a yearly growth rate of 12.5 percent. The distinct implant materials such as 316L stainless steel (ISO 5832-1), titanium and its alloys (ISO 5832-3), Co-Cr alloy and instrument materials (ISO 403, ISO 420, etc.) generally require improvement in surface characteristics in terms of biological and mechanical properties. So, the knowledge of distinct implant material properties, composition and biological responses such as corrosion and its testing procedure using distinct electrolytes is highly essential for upcoming researchers. In this study, the author mainly focused on distinct implant materials, characteristics, and chemical composition, as well as distinct types of implant corrosion and surface modification method. As future scope, challenges and distinct corrosion testing procedures are discussed. This article could become the torch bearer for the future researchers and engineers working in the biomedical sector.
