A Right Way To Calculate Pipe CP Potential Attenuation

Product Number: 51322-17599-SG

Shown on Figure 1 is a typical impressed current CP diagram. When the rectifier is first turned on, i.e. time t=0, there is no polarization yet. At that moment, the applied DC voltage is fully consumed by IR drops at anode (IRa0) and cathode (IRc0), plus original potential difference between anode and pipe (Eoca- Eocc). When t=0, the current is at the greatest value. Over time when polarization kicks in, due to adding polarization resistance, the current is gradually reduced.

Corrosion Inhibition Of Automotive Parts In Water-Ethylene Glycol Solutions

The efforts to lower automotive component weight to make cars more fuel efficient has increased the demand for aluminum alloys. In these applications, substantial amounts of heat are generated due to engine combustion, making it necessary to cool the engine systems. Metals in an engine application will rely on coolant to transfer heat. Corrosion behavior is another consideration for metals. Aluminum alloys, similar to the metals they are replacing, are sensitive to corrosion, especially in an aqueous alkaline environment.

Developing Vapor Phase Corrosion Inhibitors for Aluminum Alloys in Ethylene Glycol Coolant Solutions

Product Number: 51324-20382-SG

Different vapor phase corrosion inhibitors were evaluated to determine their corrosion inhibition for aluminum alloys in Ethylene glycol (C2H6O2) coolant mixture. When the temperature exceeds 80°C, ethylene glycol can decompose into organic acids. The resulting acidic environments cause severe localized corrosion of aluminum alloys. The corrosion behavior was studied at multiple temperatures in different corrosion inhibitors using different concentrations. Corrosion inhibitor VCI-A, VCI-B, VCI-C, and VCI-D at 2.5-3.0% dosage showed excellent corrosion protection. VCI-A, VCI-C and VCI-D maintained a steady, low corrosion rate during long term exposure by neutralizing pH and forming a hydrophobic film. They increase the polarization resistance by a significant factor, therefore, lowered corrosion rate. VCI-B inhibitor, also showed the ability to reduce the corrosion rate of aluminum in ethylene glycol solutions. However, due to its high pH chemistry, the effective dosage should be maintained at <2.5% to avoid any potential increase in pH that can promote localized corrosion or under-deposit corrosion attacks of aluminum alloys. The results of this investigation demonstrated that these inhibitors can lower the corrosion rate in water-ethylene glycol solutions by neutralizing pH and forming stable films.

When a metal or metal alloy is immersed in an electrolyte made of a conducting material of sufficient oxidizing power, such as moist soil, it will corrode according to a well-defined electrochemical mechanism. dc corrosion is a result of dissolution of material due to oxidizing reactions, liberating electrons and forming positive ions transported into the electrolyte, leading to material loss. The current-potential relationship governing this electrochemical process termed polarization, is non-linear. This relationship is often represented by a polarization curve, which is typically, an experimentally determined function. There are a number of parameters that can contribute to the final characteristics of the polarization curve within a system ranging from material parameters (e.g. material, geometry) to environmental factors (e.g. composition of the electrolyte).
