An electro-anti deposit device is coupled to an irrigation pipe for removing mineral deposit from drippers of the pipe. The electro-anti deposit device includes an engine configured to move the electro-anti deposit device along the pipe. The electro-anti deposit device also includes a mineral deposit removal module. The mineral deposit removal module includes a water container, a battery, and two electrodes. The water container may be configured to create an ionic environment at a dripper. The dripper may be covered with the mineral deposit. The battery may be configured to generate electric current. The two electrodes may be connected to two poles of the battery with a space separating tips of the two electrodes.

A method for cleaning a surface of an aluminum or aluminum alloy body by immersing the surface in a basic aqueous electrolyte formed essentially from dissolved trisodium phosphate, flowing DC current through the electrolyte and the body for cleaning, and then removing the body from the electrolyte. An additional cleaning step, which may include ultrasonic cleaning, may be performed to remove loose matter adhering to the body after the electrolytic cleaning.

The present invention concerns a method and device for oxidative erosion or for decontamination of a metallic surface, comprising a step consisting of intermittently polarizing the metallic surface to be eroded or decontaminated, placed in contact with a solution containing manganese VII, at a more anodic electric potential than the corrosion potential of said surface.

Systems and methods for beneficially affecting the surface morphology of electrically conductive materials using electrochemistry are described. The systems and methods for beneficially affecting the surface morphology of electrically conductive materials use a bimodal process in which a first current type (alternating or direct) is applied across an electrolyte between an electrode and a workpiece followed by applying a second current type different from the first current type is used. The bimodal process may be repeated one or more times.

A method for investigating an electrolyte solution for processing a component, particularly a component or a component material of an aircraft engine, by near infrared spectroscopy.
