摘要： An electrolytically acting doctor blade for pickling and cleaning curved metal surfaces comprises an electrode (2, 26, 34) embodied by a metal wire (8, 32) around which a pad (7, 30) made of a felt-like absorbent plastic material, resistant to high temperatures and to the chemicals contained in the electrolytic solution used, is wrapped; gripping means of the doctor blade on the electrode over the length of the face (F) of the doctor blade; electrical connection of the ends of the metal wire (8, 32) by means of a power supply electric cable (16) to initiate the electrolytic action; and has the gripping means of the doctor blade (1) on the electrode (2, 26, 34) connected to each other by the means placed alongside, in which the connection section, in the deformable body of the doctor blade (3) which has been made pliable, is oriented towards the face (F) of the doctor blade; a push or pull mechanism acts on the ends (25) of the doctor blade and, to obtain a reaction, with a middle part of the mechanism, connected to the middle part of the deformable body of the doctor blade (3), deforms the face of the doctor blade from rectilinear into the arched, convex or concave conformation, depending on the pull or push on the ends of the doctor blade, with respect to the middle part of the doctor blade, exerted by the said mechanism.
Different constructive forms of electrolytically acting doctor blade for pickling and cleaning curved metal surfaces with the use of different deformable electrodes are described.-

摘要： Metal surface pretreatments using ionic liquids prior to electroplating are disclosed. The surface treatments include forming an activated metal substrate surface by removing any naturally formed metal oxide layers formed on the surfaces of the metal substrates. According to some embodiments, the surface treatments include exposing the metal substrate to a non-aqueous ionic liquid. In some embodiments, an electrical current is applied to the metal substrate to assist removal of the metal oxide layer. The electrical current can be a pulsed anodic current. After activating the surface, a metal layer can be deposited on the activated surface. In some embodiments, the metal layer is electrodeposited in the same ionic liquid used to form the activated surface. The resultant metal coating is resistant to scratching and peeling.

摘要： Methods for deoxidizing metallic surfaces are disclosed. Such a method may include contacting a surface of a metal strip with one or more chemical solutions until a potential drop across a thickness of the metal strip is less than a pre-selected value. To process a metal strip such that it may be suitable for fabrication of a bipolar plate for use in a fuel cell, the metal strip may be processed until the potential drop is less then about 15 mV. A surface of the metal strip may be contacted for a first period of time with a first chemical solution having a pH of between 10 and 14. Thereafter, the surface may be contacted for a second period of time with a second chemical solution having a pH of between 1 and 3. A conductive organic coating may then be applied to the surface. Such methods are particularly suitable for use in connection with a coil coating process.

摘要： The present invention discloses a surface treatment process for enhancing both the release rate of metal ions from a sacrificial electrode, and the working life of the electrode. A high density of micro pores are formed on the surface of the sacrificial electrode. Chlorine ions are then implanted into the pores. The chlorine ions prevent a passive film from forming on the sacrificial electrode during use, in which an electric current flows through the sacrificial electrode.

摘要： A surface of a light-metal alloy is anodically polarized in a cleaning process. The surface is cleaned with a solution containing phosphoric acid, alcohol, and optionally fluoride. Additionally, the surface is passivated in an oxidizing process using, for example, fluoride ions or an aqueous oxidizing agent. Preferably, the light-metal alloy has a relatively high Al or Mg content. This method is suitable for preparing the surface for a subsequent coating operation.

摘要： The application of electrochemical reduction treatment liquids and electroless reduction treatment liquids to elements such as circuit boards for cleaning metallic surfaces in preparation for soldering is accomplished using a wave of the treatment liquid over a liquid tank. A wave treatment has advantages over spraying, which causes too much atomizing, and dipping, which is slow and requires complicated conveyors that are multi-directional. The method comprises forming a wave of reduction treatment liquid in an atmosphere having a limited included oxygen content and passing components through the wave so the reduction treatment liquid contacts the surfaces to be solder coated.

摘要： The present disclosure sets forth improvements in a cleaning procedure to clean electrodes exposed to hypochlorite in a measuring device. Typical measuring electrodes are made of platinum, gold, silver or other conductive metals. The electrode is dipped in a strong acid bath, a sacrificial oxide coated titanium electrode is placed in the bath and a DC power source is connected between the metal electrode requiring protection and the sacrificial electrode to create current flow until the surface has been treated. Current flow accomplishes the treatment after which the electrode can be removed and used in measuring hypochlorite concentration.
