Abstract The potential for galvanic corrosion between carbon steel and duplex (22Cr) stainless steel in impure ethylene glycol (CH2OHCH2OH) is assessed. The temperature dependence of the corrosion is determined, as well as the effect of temperature on the conductivity of dry, wet, and impure wet ethylene glycol. The temperature dependence of the corrosion can be explained by the change in electrical resistance of the glycol with temperature. The authors also show the importance of testing corrosiveness by using the actual working fluid rather than a simulation fluid.

Nitric Acid Solutions

Abstract Chemical and galvanic corrosion experiments at 35 C show that ductile vanadium is resistant to corrosion in substitute ocean water. It is also resistant in 60 percent sulfuric and 20 percent hydrochloric acids but corrodes rapidly in nitric acid solutions. Vanadium is less noble than stainless steel and copper and more noble than aluminum, magnesium and steel (SAE 4130) in substitute ocean water. 6.3.18

Abstract This paper deals with the issue of welding two different materials – titanium and stainless steel (UNS N50400 + X5CrNi 18-10). These two materials have completely different chemical compositions and mechanical properties; therefore, process of their mutual welding is complicated. Melting temperature of both materials is also different. An innovative MIG LSC arc welding method with an additional material has been selected for this purpose. A protective atmosphere was used in order to avoid galvanic corrosion of materials that would preclude the welding process. Aforementioned atmosphere contained 100% Ar. The MIG LSC welding method was designed by Fronius. Presented experiment compares utilization of following 4 different electrodes (additional material) for the welding of titanium and stainless steel: Ti, Fe, corrosion-resistant Fe and CuSi3 electrode. Tensile test was utilized for evaluation of weldment mechanical properties. Measured results were supplemented with a metallographic analysis snapshot and tensile diagram.

Abstract The presence of corrosion on or within structures is of major concern as corrosion reduces the integrity of the materials which could potentially result in large-scale failures of structures and equipment.1 The United States Navy is an organization that actively works to prevent large equipment failure due to corrosion. One such problem is the corrosion of the friction brake assembly on the MK50 Weapon Station, which has recently been experiencing corrosion between the friction brake and its set screw preventing it from operating correctly. The friction brake was known to be stainless steel; however, the set screw was of unknown composition. Through elemental analysis it was determined that the MK50 Weapons Station friction brake set screw was similar in composition to commonly available black oxide coated steel screws. Electrochemical polarization measurements of the friction brake assembly components revealed that the set screw and the friction brake were electrochemically dissimilar metals which resulted in the galvanic corrosion of the assembly when out at sea. The electrochemical polarization measurements of a stainless steel screw showed a corrosion potential similar to that of the friction brake; therefore, replacing the current set screw with a stainless steel screw would decrease the galvanic potential difference between the set screw and the friction brake. This proposed solution is expected to slow or prevent further corrosion of the MK50 Weapon Station ensuring the combat readiness of the equipment.
