Can Dynamic Bubble Templating Play a Role in Corrosion Product Morphology.
(30/05/2013)
Dynamic templating as a result of cathodic hydrogen gas production is suggested as a possible mechanism for the formation of tube-like corrosion products on an unlined cast iron pipe in a drinking water distribution system. Mounds of corrosion product, with protruding tubes and freestanding tubes, were observed within a single 30 cm section of piping. Internal morphologies for all shapes were texturally complex although mineralogically simple, composed of two iron oxide/oxyhydroxides minerals: alpha-FeOOH (goethite) and Fe304 (magnetite). Static templating by either microorganisms or minerals was rejected as a possible mechanism for tube formation in this study....
