摘要： Cathodic protection of steel in concrete is provided by locating an anode assembly including both a sacrificial anode and an impressed current anode in contact with the concrete and providing an impressed current from a power supply to the anode. The impressed current anode forms a perforated sleeve surrounding a rod of the sacrificial anode material with an activated ionically-conductive filler material between. The system can be used without the power supply in sacrificial mode or when the power supply is connected, the impressed current anode can be powered to provide an impressed current system and/or to recharge the sacrificial anode from sacrificial anode corrosion products.
摘要翻译：通过将包括牺牲阳极和外加电流阳极的阳极组件定位成与混凝土接触来提供混凝土中钢的阴极保护，并从电源向阳极提供外加电流。外加电流阳极形成围绕牺牲阳极材料的棒的穿孔套管，其间具有活化的离子导电填料材料。该系统可以在牺牲模式下没有电源的情况下使用，或者当电源连接时，外加电流阳极可以被供电以提供外加电流系统和/或从牺牲阳极腐蚀产物对牺牲阳极再充电。

摘要： According to various embodiments, a system includes a turbine engine component that includes a first material having a surface exposed to a fluid flow path and a sacrificial anode layer disposed on the surface. The sacrificial anode layer includes a second material that is electrochemically more active than the first material and the second material is configured to preferentially corrode to protect the first material from corrosion.

摘要： A sacrificial anode assembly for cathodically protecting and/or passivating a metal section, comprising: (a) a cell, which has an anode and a cathode arranged so as to not be in electronic contact with each other but so as to be in ionic contact with each other such that current can flow between the anode and the cathode; (b) a connector attached to the anode of the cell for electrically connecting the anode to the metal section to be cathodically protected; and (c) a sacrificial anode electrically connected in series with the cathode of the cell; wherein the cell is otherwise isolated from the environment such that current can only flow into and out of the cell via the sacrificial anode and the connector. The invention also provides a method of cathodically protecting metal in which such a sacrificial anode assembly is cathodically attached to the metal via the connector of the assembly, and a reinforced concrete structure wherein some or all of the reinforcement is cathodically protected by such a method.

摘要： An anti-corrosion plug for closing a threaded condensate drain opening in a compressor air tank. The plug is formed from a material having a lower potential in the electrochemical series than said air tank to prevent electrolytic corrosion of the tank. The plug has a central cavity open to receive any condensate in the tank. An acid neutralizing insert, for example, of limestone, is located in the cavity to neutralize any acidity in the tank condensate.
