What is Marine Zinc Anode
Zinc alloy sacrificial anodes help prevent corrosion of important metals on board.Typically, there will be at least two metals on board, with zinc being the third purposely sacrificed. Zinc anodes are the unsung heroes that protect metal and machinery on ships. Because the boat sails on water, it is necessary to install zinc anodes in order to keep the boat's engines and propellers available for a long time.
Overview
Definition
Marine zinc anodes, also known as Marine zinc alloy sacrifice anodes, are essentially a metal that is attached to the underwater part of a boat, usually on the propeller shaft or propeller. Zinc anode is an alloy material that replaces the corrosion of more valuable equipment such as steel structures, engines or propellers on ships.
Working Principle
The zinc anode principle is an electrochemical principle used to prevent corrosion of metals. It uses zinc as an anode, which forms a uniform protective film of zinc oxide on the metal structure. When the metal structure is exposed to moisture, the zinc anode actively corrodes and extends its protective effect to the metal structure. This is due to the higher electronegativity of zinc, which makes it more susceptible to oxidation and corrosion.
