WebBy means of a pipe’s inner surface grinding, a single-phase nanostructured austenite was formed on the surface of an AISI 304 stainless steel. The electrochemical corrosion behavior was compared with a coarse-grained counterpart of identical surface roughness. Experimental results show that the nanostructured austenite shows a higher pitting … WebPitting corrosion is usually the result of galvanic corrosion. This occurs when two different metals and water come together as electrolytes. This creates charges – like in a battery, electrons flow. The result is a small pit. The electrons flow from the base metal to the noble metal and produce the pitting. Therefore it is good craftsmanship ...
