These two layers protect the surface from electrolytic corrosion. Duplex nickel plating finds applications in various industries, including automotive, computer hardware, steel industry, electronics, aerospace and oil & gas, among others.
Current passage or electrolytic corrosion. If current is allowed to flow through the rolling elements, sparks can create pitting or fluting on the bearing surfaces.
These segments, called cased pipelines, are subject to not only the normal corrosion caused by time, moisture and soil chemistry, but also electrolytic corrosion from contact between the metals of the carrier pipe and its casing.
Electrolytic corrosion sets in if aluminum pontoons sit on salty, wet carpet, resting atop stainless bolts and other trailer hardware.
The potential differences can be created by dissimilar materials with different free energy levels (galvanic corrosion) or by external DC currents in structure (electrolytic corrosion).
If water is present, well-soluble chlorides form an aqueous solution or become liquefied, and that can cause intensive electrolytic corrosion even at relatively low temperatures because KCl and Ca[Cl.sub.2] are well-soluble compounds.
This trend is changing as a result of more active fluxes and localized areas of entrapped flux residue, leading to electrochemical migration and electrolytic corrosion.
Any yachtsman can tell you all about the perils of electrolytic corrosion, and, although these bikes have been built to a pretty high standard, it seems likely that sooner or later some alloy part will cement itself to the neighbouring steelwork pretty well irrevocably.
Jeff LeBlanc, P.E., Amitech applications engineering manager, said Flowtite pipe is immune to galvanic and electrolytic corrosion and is widely used for potable water and sanitary sewer systems and industrial pipe applications.
Relatively immune to electrolytic corrosion, concrete is usually durable in underground service but should have a protective coating if the soil is acidic.
