The disclosure relates to a method and system for treating ballast water and ballast water treatment systems in order for treatment effects to be carried out, such as controlling the transportation of undesirable and invasive marine organisms. In particular, the disclosure relates to methods and systems for applying a superimposed time-varying frequency electromagnetic wave comprising both AC and DC components in a pulsating manner to ballast water within a ballast water treatment system.

The invention relates to a system for the local surface treatment of an aeronautical part (1) to be treated.

Said system is characterised in that it comprises a plurality of containers (18, 19, 20, 21) each comprising a treatment product (22, 23, 24, 25), at least one bath enclosure (102a, 102b) suitable for delimiting a fluid-tight space (26a, 26b) between this bath enclosure (102a, 102b) and a portion (101a, 101b) of the part to be treated, and a controlled circuit (10) for supplying said fluid-tight space (26a, 26b) with treatment product (22, 23, 24, 25) the containers (18, 19, 20, 21) connecting at least this container (18, 19, 20, 21) to said fluid-tight space (26a, 26b) and comprising valves for managing the supply to the fluid-tight space by one or more containers from the plurality of containers.

A part-carrier for electrolytically treating geometrically complex parts includes a reinforcement vertically supporting supports that are movable in rotation and designed to carry the parts to be treated, and a control member which, when activated, pivots the movable supports in sequence to either side of a neutral initial position. Application to electroplating.

Various embodiments include a sealed laminated metal structure. This laminated metal structure has a metal layer, where the metal layer has a first surface and an opposite second surface. A material is laminated on each of the first and second surfaces of the metal layer. In some cases, the laminated metal structure is removed from a larger laminated sheet of metal. The laminated metal structure is subjected to alternating current electrolytic deburring and cleaning to remove any burrs along the perimeter edge. After deburring and cleaning, a sealer, which is a phosphate compound, is deposited on the perimeter edge of the laminated metal structure where the metal is exposed using alternating current.

According to one embodiment, a pattern transfer mold includes a base body, first and second stacked bodies, first and second electrodes. The base body includes a base unit including a first surface, a first protrusion provided on the first surface and having a first side surface, and a second protrusion provided on the first surface, separated from the first protrusion, and having a second side surface opposing the first side surface. The first stacked body is provided on the first side surface, and includes first conductive layers and a first insulating layer. The second stacked body is provided on the second side surface, separated from the first stacked body, and includes second conductive layers and a second insulating layer. The first electrode is electrically connected to at least one of the first conductive layers. The second electrode is electrically connected to at least one of the second conductive layers.

Customizable methods of protecting select regions of a light metal or alloy workpiece, such as a wheel (10), from corrosion are provided. The light metal or alloy may be magnesium, aluminum, or titanium. A first region (50) of the exposed surface (40) is identified that has increased exposure to corrosive agents in an external environment (in service conditions) as compared to a second region (52). Thus, a corrosion resistant coating is selectively formed over the first region (50) of the exposed surface (40). The second region (52) may have a second distinct corrosion resistant coating. Methods for selectively and efficiently forming such corrosion resistant systems are provided. In certain methods, the locations where the corrosion resistant coating is applied are controlled by immersing only select portions of or selectively masking the workpiece in a micro-arc oxidation electrolyte bath. In other methods, the thicknesses of the coatings are locally tailored by controlling the electric field.

A device is for treating and packaging implants. The device includes a container including a chamber therein. The chamber is closed by a removable seal. The device also includes a carrier sized and shaped to be inserted into the chamber. The carrier includes a carrying structure configured to connect an implant thereto. A portion of the carrier may be formed of an electrically conductive material.

The present invention relates to a device comprising a device casing and a first and second flexible contact extending from the casing, each comprising a mounting means and a flexible applicator portion extending therefrom, wherein the first and second flexible contacts are each adapted to receive conductive fluid and subsequently to apply the conductive fluid to a surface, and one of the first and second flexible contacts is positively charged, and the other is negatively charged, relative to one another.

An electrochemical treatment system includes a treatment fluid supply manifold, a fluid return manifold, and an electrode section connected to the treatment fluid supply manifold. A plurality of treatment fluid supply ports feed fluid through or across the electrode and a plurality of fluid return ports proximate the treatment fluid supply ports are connected to the fluid return manifold. A porous pad is coupled to the electrode section for contacting a substrate to be treated and receives the treatment fluid via the plurality of treatment fluid supply ports. The plurality of fluid return ports remove spent and excess treatment fluid and gases from the substrate, the surrounding air, and the porous pad.

The present disclosure provides devices, systems and methods with applicability in the coating of surfaces, in particular three-dimensional surfaces, via anodization reactions. For example, the disclosed devices, systems and methods find use in the formation of microstructured or nanostructured layers, e.g., metal oxide microstructured or nanostructured layers, via anodization on a variety of devices including, e.g., medical devices. Devices modified with one or more microstructured or nanostructured layers are also provided.
