Influence of AAO Treatment Parameters on Characteri-zations of Surface Pores on 316L Stainless Steel
Recently a new kind stent, porous drug-eluting stent, has been developed to overcome the problems of bare metal stent (BMS) and drug-eluting stent (DES), and the clinic results reveal that it combined the advantage of BMS and DES. In this paper, a new method to fabricate surface pores on 316L stainless steel stent using anodic oxidation of aluminum mask film deposited by magnetron sputtering on 316L substrate was reported. The effect of experimental parameters, such as anodization time, anodization voltage, anodization solution and anodization temperature, on the pores size distribution and density are investigated using SEM. It is found that the pores characterizations strongly depend on anodization time and pores expanding rate through AAO films and on stainless steel surface.
