Study on Anti-bacterial Properties of Ni-Ce-P / nano-TiO_2 Chemical Composite Plating on Mg Alloy
Adding nano-TiO2 to the surface of AZ91D alloy which was plated by Ni-Ce-P,the Ni-Ce-P /nano TiO2 composite plating was obtained.The surface morphology,section morphology and antibacterial properties of the composite plating were analyzed at the same time.The results show that the thickness of the composite plating is about 20 μm and there is a MgO bonding layer between deposited coating and matrix.The potochemical catalysis effect of the composite plating is evident and antibacterial rate reaches more than 90%,which has obvious antibacterial effect.
