- G0410304 Experimental Investigation for Prevention of Iron Rust in Water Flow using Characteristics of Polar Crystal Metals
抄録
The important factors to produce the iron rust are oxygen, existence of electrolyte such as water and the hydrogen ion. Experiments have been carried out to prevent iron rust in water flow by developing the ion balls having the structure of polar crystal metals. Ion balls make it possible to emit e ion particles because they are composed of the polar crystal metals. The water temperature and water flow speed are around 25℃ and 10 cm/s, respectively. The diameter of ion ball is approximately 7.30 mm. The results obtained show that e- ion particles emitting from ion balls in water flow bring to change pH in the range of around 7.2 to 8.2 and e- ion particles may react with FeO(OH) produced during the rust generation process, and then the black rust (Fe_3O_4) as passive state film of 0.1 μm to 100 μm in thickness is generated in iron surface. This fact shows that the ion balls developed in the study makes it possible to restrain the progress of red rust at iron surface.
