An electrical contact element formed of sheet metal having a first region and a second region. Each one of the first and second regions is coated with a coating including a first layer containing a first material having a lower standard electrode potential than the sheet metal material. The coating includes a second layer in the first region which is absent in the second region. The second layer is arranged underneath the first layer and contains a second material that has a lower standard electrode potential than the first material.

A selectively removable engine anode having a metallic anode base with a threaded configuration disposed proximal to a lower end thereon and on an outer surface, a flanged platform extending radially along a longitudinal length of the base to define an outer flange diameter, and a cantilevered retention member directly coupled to the flanged platform and having a diameter less than the outer flange diameter. The anode includes a galvanic anode with a first anode end coupled to the flanged platform, a second anode free end opposing the first anode end, and an anode length separating the first anode end and the second anode free end, wherein the galvanic anode and the flanged platform encapsulate the cantilevered retention member, the anode base is selectively removably couplable to a plug that is operably configured to be selectively coupled to a marine engine.

A computing device of an information handling system includes a connector that receives a component, the connector including a contact that forms a physical connection, with the component, that supports an electrical connection between the connector and the component, the contact includes an interface surface, disposed in a high corrosion risk area of the connector, that forms the physical connection with the component while the component is disposed in the connector. The computing device also includes a corrosion management component that: reduces a rate of corrosion of the contact in the high corrosion risk area of the connector, and increases a second rate of corrosion in a low corrosion risk area of the connector.

A method of making cerium citrate includes combining cerium carbonate and citric acid to produce cerium citrate and carbon dioxide. The cerium citrate is substantially free of negative ions other than citrate. The cerium citrate can be used in a corrosion inhibitor composition.

An apparatus for enhancing the performance of skimmer baskets in swimming pools and preventing corrosion in pool equipment is disclosed. The apparatus may be disposed beneath a skimmer basket and may function as a filter for solid waste, while simultaneously acting as a sacrificial component for corrosion prevention of essential pool equipment. Manufactured using a galvanic anode, the apparatus may effectively prevent debris from entering the skimmer pumping system. The dimensions of the apparatus may be customized based on various factors, such as the size and shape of the pool, the skimmer basket, and the pump system used. With adjustable or modular components, the apparatus allows users to adapt the device to their specific needs and is designed for easy installation, removal, and cleaning. The apparatus may be installed in swimming pools, hot tubs, or other water-containing structures requiring filtration and corrosion protection.

An example fluidic device may comprise a fluidic die and a support element coupled to the fluidic die. A fluid channel may be arranged within the support element and may define a fluid path through the support element and a fluid aperture of the fluidic die. A conductive element may be arranged in the fluid path and be coupled to a ground of the fluidic die. A material and size of the conductive element may be selected to engender galvanic effect at an approximately zero potential.

A corrosion resistant article including an aluminum substrate and a corrosion-inhibiting cerium based corrosion inhibitor corrosion inhibiting additive on the aluminum substrate, the corrosion inhibiting additive comprising an anodic corrosion inhibitor and a cathodic corrosion inhibitor, the anodic corrosion inhibitor greater than 25 wt % of the total inhibitor.

The invention relates to an offshore installation, comprising an underwater foundation structure, a construction placed onto the foundation structure, a docking device for a boat, and a device for cathodic corrosion protection for the underwater foundation structure, said device having at least two anodes (2), which are arranged at a distance from each other and are each fastened to a beam (4) or a support of the foundation structure, the extension arms or the supports being connected directly to the foundation structure below the waterline.

An electrical connector includes an electrically insulating body and a self-passivating contact held at a higher voltage than a non-passivating contact. The self-passivating contact includes a first electrically conductive material that forms an electrically insulating passivation layer when exposed to water or other aggressive environment. The non-passivating contact includes a second electrically conductive material that is unreactive when exposed to water or other aggressive environment. The passivation layer on the self-passivating contact prevents electric current from flowing between the self-passivating contact and the non-passivating contact through the water or other aggressive environment.
