Process Mapping of Laser Glazing Aisi 316l Stainless Steel for Biomedical Implants

Characterization of Porous TiO2 Surfaces Formed on 316L Stainless Steel by Plasma Electrolytic Oxidation for Stent Applications

In this study, a porous oxide layer was formed on the surface of 316L stainless steel (SS) by combining Ti magnetron sputtering and plasma electrolytic oxidation (PEO) with the aim to produce a polymer-free drug carrier for drug eluting stent (DES) applications. The oxidation was performed galvanostatically in Na3PO4 electrolyte. The surface porosity, average pore size and roughness varied with...

Dynamic Mechanical Response of Biomedical 316L Stainless Steel as Function of Strain Rate and Temperature

A split Hopkinson pressure bar is used to investigate the dynamic mechanical properties of biomedical 316L stainless steel under strain rates ranging from 1 × 10(3) s(-1) to 5 × 10(3) s(-1) and temperatures between 25°C and 800°C. The results indicate that the flow stress, work-hardening rate, strain rate sensitivity, and thermal activation energy are all significantly dependent on the strain, ...

A Review on Surface Coatings on 316L Stainless Steel to Improve Biomedical Properties

Stainless steel 316L has widely used as bioimplants in cranial plates, dental implants, bone fracture fixation, prothestic joints. However, low wear resistance, in some cases susceptibility to pitting and crevice corrosion in body environment and release of toxic ions from the surface are the basic disadvantages which this material prone to be. It has still applied as a temporary biomaterial du...

Electrochemical polishing of 316L stainless steel slotted tube coronary stents.

Surface smoothness is one of the properties determining the performance of stents. Therefore, surface polishing shows its importance in the exploitation and production of stents. The present study explores electrochemical polishing of 316L stainless steel slotted tube coronary stents produced by laser cutting. Acid pickling was also studied as a pre-treatment of electrochemical polishing of the...
