Surface modification of implants for bone surgery

The study discusses the methods of surface modification methods for AISAI 316 L steel and Ti6Al4V ELI titanium alloy, dedicated to complex design implants used in bone surgery. Results of structural tests have been presented along with those evaluating the physicochemical properties of the formed surface layers. Clinical feasibility of the surface layers has also been evaluated. The developed surface modification methods improved the resistance to pitting, crevice and stress corrosion and ensured better biocompatibility. Moreover, the layers formed are marked by plasticity. Results of the tests performed show applicability of the evaluated methods of surface modification in complex shape implants for the clinical use.
