To evaluate how laser surface melting alters the microstructure, crystallographic texture, and surface topography of AZ31B magnesium alloy to improve its in vitro degradation behavior.
Simulated thermokinetic effects during laser melting using a multiphysics finite element model.
Characterized microstructure, crystallographic texture, and phase distribution using SEM, XRD, and EBSD, alongside white light interferometry for topography.
Evaluated wettability and bioactivity via contact angle testing and 7-day immersion studies in simulated body fluid.
Laser processing created a refined microstructure with a predominantly basal crystallographic texture, alongside increased surface roughness and higher β-phase (Mg17Al12) concentration at cell boundaries with rising laser fluence.
Laser surface melted specimens exhibited improved wettability, increased corrosion resistance, and accelerated deposition of bone-like hydroxyapatite minerals during simulated body fluid immersion compared to untreated alloy.
