乙醇对光辅助阳极电沉积CeO2薄膜的影响

In this paper, ceria thin films have been anodic deposited with photo assisting in the electroplating solution containing various volume ratio of ethanol (0, 10, 40, 70 and 100 % V/V) onto 316L stainless steel surface. Results show that the film thickness of ceria layers and corrosion protection increase whereas the film porosity decrease with the augment of ethanol content from 0 % V/V to 70 % V/V; The important role of ethanol content in enhancing the anodic deposition rate of ceria film may be mostly achieved by the simultaneously photo generated electrons. Using a deposition bath solution containing 70% V/V ethanol, a layer with the minimum porosity of 24.1%, maximum thickness of 48.4 nm, and minimum corrosion current density of 3.40 ×10-8 mA.cm-2 has been obtained.
