cathodic protection is one of the most efficient methodsto prevent metaI from electrochemical corrosion£®It impresses certain cathodic current to the protected metals and makesØ¥1em produce cathodic polarization£®When their potential are lower than certain values£¬the anode dissolving
process of corrosion will be effectively controlled£®According to the different manners of providing cathodic current£¬cathodic protection will be divided into two types£¬including sacrificial anodes and impressed current system£®Sacrificial anode method is to connect the protected metallic struc-tures with a more active metal o r aIIoy£¬th rough thei rdissolving£¬the protected structures shall get the necessary current and will be protected effectively£®Impressed current method is to convert the AC into low voltage DC and then transmit the protection current to the protected metallic structu res th rough auxiIiary anodes. |
