Abstract
An apparatus for the cathodic corrosion protection of metal surfaces immersed in a liquid electrolyte, preferably seawater, the metal surfaces preferably being provided at the stern tube seal of a ship, by means of at least one sacrificial anode 7 which is secured to a component which is moved relatively fast relative to the electrolyte, preferably at the propeller shaft 1 of a ship, is characterised by the use of a housing 8 which surrounds the sacrificial anode and is preferably electrically insulated relative thereto, with the wall of the housing being spaced from the sacrificial anode at least in the region of one of the side surfaces thereof and being provided there with apertures for the passage of the electrolyte, with the spacing of the passage openings from the sacrificial anode and/or the clear area of the passage openings being so selected that during the operational movement, preferably rotation, of the housing together with the sacrificial anode, the speed of flow of the electrolyte in the interior of the housing does not amount to more than 0.3 m/sec. <IMAGE>
