Surface nanocrystallization enhances the biomedical performance of additively manufactured stainless steel.

Journal of Materials Chemistry B, 2023
Additive manufacturing enables the fabrication of patient-specific implants of complex geometries. Although selective laser melting (SLM) of 316L stainless steel (SS) is well established, post-processing is essential to preparing high-performance ...

Surface nanocrystallization of hydroxyapatite coating

Acta Biomaterialia, 2008
Nanocharactered biomaterials, such as nanopowders, nanocrystalline compacts and nanostructured films, as well as materials with nanoscale roughness, have attracted much attention recently, due to their clear effects on cell response. Surface nanocrystallization of plasma-sprayed hydroxyapatite (HA) coating can be realized by conventional post-heat ...
