Developing a new laser cladded FeCrMoCB metallic glass layer on nickel-free stainless-steel as a potential superior wear-resistant coating for joint replacement implants

摘要: Abstract Biomedical implants are made of biomaterials such as titanium, cobalt-based alloys or stainless-steel depending on which is the most suitable. However, metallic have failed to prove high wear resistance alongside acceptable biocompatibility. Recently, glasses (MG) attracted more attention for joint replacement due their superior and biocompatibility, however, they brittle material constrained in size few centimeters. Therefore, MG coating layer ductile-core alloy like would overcome drawbacks develop a well-functioning implant. In this research, FeCrMoCB laser cladded nickel-free stainless steel using three levels specific energy, scanning speed, spot overlap percentage different amorphous-crystalline composite structures. The samples showed both dry Ringer's solution conditions (up 270 times that substrate) demonstrating comparable rate with common leads promoted durability. Furthermore, cell-culture test applied substrate good cell morphology growth surfaces indicating an cytocompatibility substrate.
