The surface of Ni-free Zr60Ti6Cu20Fe5Al10bulk metallic glass (BMG) was modified to be bioactive by using the micro-arc oxidation technique. A rough and porous oxide layer mainly containing tetragonal ZrO2and amorphous SiO2incorporating some Ca and P was formed. This layer adhered very well to the BMG substrate and exhibited a superior biocompatibility.
