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 […]

The guide to metal corrosion in boats is intended to give you a fundamental understanding of what corrosion is, what causes and affect it, and help you determine which anode material is right for your boat. Of all the complicated subjects a boat owner needs to know, corrosion is probably the most confusing. Corrosion can

Electrochemical corrosion is that metal and electrolyte form two electrodes to form a corrosion galvanic cell. For example, iron and oxygen, because the electrode potential of iron is always lower than that of oxygen, iron is the negative electrode and is corroded. It is characterized by the formation of many small bulges with different diameters
