摘要: (18)O tracer is used to investigate the development of porous anodic films at constant current in phosphoric acid on electropolished aluminum. A barrier layer and region form initially with pore size related surface texture substrate. Subsequently, major pores emerge, their sizes anodizing voltage. The evolution film accompanied by increases growth rate formation efficiency. ions a preformed oxide are retained during anodization nonenriched electrolyte, being partitioned among (i) texture-dependent porosity, (ii) walls pores, and, diminishing amounts, (iii) inner layer.
