effect of processing parameters on pore structure and thickness of anodic

... upon concen- tration of sulfuric acid. Higher electrolyte concentration increased oxide dissolution and oxidation growth. With faster oxidation and dissolution, the pore size decreased. Thus, pores ... molecules once pass into one end (inner) of the pore would only come out from the other end (outer) of the pore without diffusing out from the middle of the pore- tunnel. The...
