The bioactive calcium titanate coating was prepared by laser cladding on a (Zr0.62Cu0.23Fe0.05Al0.1)97Ag3 bulk metallic glass. The coating, which was mainly composed with dendrite calcium titanate and a little calcium pyrophosphate, formed a strong bonding with the substrate. The cladding process generated a crystallized heat-affected zone with a thickness of 300 μm and other parts in the substrate remained amorphous structure after laser cladding. It was demonstrated that surfaces of Zr-based bulk metallic glasses can be made bioactive and that laser cladding techniques were useful methods in the purpose of making Zr-based bulk metallic glass surface bioactive.
► The CaTiO3 coating was prepared by laser cladding on a Zr-based bulk metallic glass. ► The coating bonds tightly to the substrate without visible cracks and porosities. ► It provides a method for preparing bioactive coatings onbulk metallic glasses.
