The novel properties for the corrosion resistance in a 5% NaCl salt-sp
ray-test and the inhibitory capability of Ni-TiO2 composite coating fo
r the growth of pathogenic bacteria (E. faecalis. E coli, and P. aerug
inosa), under fluorescent irradiation and using a ''drop-method'' anti
bacterial experiment was set forth in this paper. The antibacterial ac
tivity of Ni-TiO2 composite coating became more significant by increas
ing the TiO2 contents in the composite coatings.
