Alloy cast iron with high corrosion resistance in some media can be obtained by adding certain alloying elements into cast iron. High silicon cast iron anode is one of the most widely used, a series of alloy cast iron anode containing 10% ~ 16% silicon is called high silicon cast iron anode. PERFORMANCE OF HIGH […]

High silicon cast iron anodes were first used in the United States, initially in the laboratory, and by the early 1980s, they began to be widely used in industrial production. The 14.5% silicon iron anodes were found to corrode easily in seawater, so chromium was added to the anodes in seawater to reduce the corrosion

Cathodic protection is a kind of electrochemical protection technology. Its principle is to apply an applied current to the surface of the corroded metal structure, and the protected structure becomes the cathode, so that the electron migration of metal corrosion can be inhibited and the corrosion can be avoided or weakened. Definition Cathodic protection is
