Abstract

This research proposes the development of amorphous-crystalline FeCrMoCB layer as a promising biomaterial for bone-implant applications. The FeCrMoCB amorphous powder was laser cladded on nickel-free stainless-steel (Cronidur30) using three laser specific energies (E s ) levels (31.8, 27.5 and 23.4 J/mm 2 ) to attain different amorphous contents. The amorphous-crystalline structure and the microstructure were investigated using X-ray diffraction and scanning electron microscope, respectively. Later, the corrosion rate and the wear rate in simulated body fluids (SBF) were evaluated to investigate the advancement of the artificial amorphous-crystalline structure of laser cladded FeCrMoCB metallic glass (MG) composite via electrochemical corrosion test and pin-on-disc test, respectively. The hardness and Young's modulus (E) were acquired using nanoindentation measurement while the cytocompatibility was evaluated by MTT assay using MC3T3 cell-lines. The material characterization showed that increasing of E s resulted in decreasing the amorphous phase and increasing the crystalline phase. The laser cladded FeCrMoCB MG composite showed significant enhancement of the corrosion and wear resistance in SBF implying longer implant service time. This advancement behavior is not only superior to the uncoated substrate, but also compared to other biomaterials including Zr-based MG, Ti6Al4V, and CoCrMo alloys in SBF. Finally, the FeCrMoCB MG composite showed an acceptable cytocompatibility behavior bringing promising enhanced characteristics for bone-implant material.
