In this study, nano-silicon (Si) thin films were deposited on biodegradable Fe–1.5Mn–1Si substrate by pulsed laser deposition (PLD) method. Biodegradable metallic materials represent a good solution in implantology field based on the elimination of the second surgical operation required for the extraction of the material. Also, using biodegradable materials medical complications between the metallic implant and the human body that might appear during the recovery period are excluded. In this sense we propose a metallic material based on iron with a longer degradation period compared to Mg-Ca based materials. Scanning electron microscopy (SEM) and X-ray dispersive energy analyze (EDAX) were use to analyze the implant material surface before and after Si thin film deposition and before and after implantation.
