Cathodic Protection Explained

Cathodic Pro­tec­tion is the process in which met­als and com­pos­ite met­als can be used as sac­ri­fi­cial anodes to pro­tect other metal from gal­vanic cor­ro­sion, Elec­trol­y­sis and Wood Rot.    Cathodic pro­tec­tion in the marine envi­ron­ment refers to pro­tect­ing the ves­sels drive, steer­ing and other sub­merged metal parts using a block of Mad­dox, Zinc, Alu­minium or Mag­ne­sium as a sac­ri­fi­cial anode.
