Corrosion on polished and laser-textured surfaces of an Fe-Mn biodegradable alloyHočevar, Matej (Avtor) Donik, Črtomir (Avtor) Paulin, Irena (Avtor) Kocijan, Aleksandra (Avtor) Tehovnik, Franc (Avtor) Burja, Jaka (Avtor) Gregorčič, Peter (Avtor) Godec, Matjaž (Avtor) Fe-Mn alloylaser texturingcorrosionbiodegradableEDS analysesFe-based biodegradable alloys such as Fe-Mn are interesting for biodegradable implants; however, their corrosion rate for such applications is too low. Here, nanosecond-laser surface texturing is applied as a successful surface treatment for increasing the degradation rate of an Fe-Mn alloy. Laser texturing increases the surface area by increasing the surface porosity and generating a super-hydrophilic surface. Electrochemistry tests revealed that the laser-textured samples have a higher corrosion rate than a polished sample, thus enhancing the biodegradability of the Fe-Mn alloy. EDS analyses revealed a significantly higher content of Mn on the surface in the oxidized layer compared to the bulk Fe-Mn composition, which is one of the reasons for the increased corrosion rate. This work demonstrates the potential of laser-treated surfaces of biodegradable metals for biomedical applications.20172017-12-21 07:48:35Neznano99022sl
