Corrosion behavior of biodegradable Mg-based alloys via femtosecond laser surface melting

Abstract:

The effects of femtosecond (fs) laser treatment on a biocompatible Mg-Ca-Zn alloy were systemically analyzed. The fs laser altered the surface microstructure of the Mg-Ca-Zn alloy, resulting in reduced corrosion through localized melting and rapid solidification. Treatment with appropriate laser energy (500 Hz) generated an exceptionally thin modified layer (∼2 μm) with a uniformly refined microstructure. Laser-induced remelting of the secondary phase reduced galvanic corrosion and prevented ...
