AN APPARTUS AND A METHOD FOR PROCESSING STAINLESS STEEL AND AN IMPROVED STAINLESS STEEL FOR BIOIMPLANTS THEREOF

摘要

The present invention provides a simple, single step and time efficient method and apparatus for developing ultrafine grained microstructure stainless steel having enhanced wear resistance, corrosion resistance, biocompatibility, cellular response and hem-compatibility for bio-implant applications. The processed stainless steel showed 50% reduction in corrosion, high resistance against localised pitting and 50% reduction in wear in simulated body fluid. In addition, the processed steel demonstrated better cell viability, significantly lower platelet adhesion and plasma adsorption signifying high thrombo-resistance and thereby making it highly desirable for bio-implant applications. The present invention eliminates the long processing steps and do not need any specialized equipments and also eliminates the post process treatments.
