The Effect of Pressure on the Electroless Deposition Process

Abstract

EFFECT OF ROUGHNESS ON OXIDATION OF Fe 5. The relative thickness of the wiistite layer in the oxide scale decreased as the roughness of the iron surface increased. This behavior showed that there was a lowered diffusion rate of iron ions through the wiistite layer that formed on a rough surface.6. The most likely reason for the lowered iron ion diffusion rate is the blocking of the diffusion path by small voids in the oxide scale that forms over rough surfaces. These voids, which were detected in the oxide layers on all roughened Specimens, but not on smooth ones, act as barriers to ion diffusion and thereby lower the rate at which a roughened specimen oxidizes.
