陰極保護

Metal parts submerged in seawater, such as a ship’s hull, are exposed to electrolytic conditions that lead to corrosion. If a more-reactive metal is attached to the ship’s hull, this new metal acts as a cathode and is now being protected; the sacrificial anode corrodes instead of the hull. Indium metal enhances the activation of aluminum alloy sacrificial anodes. This anti-corrosion application is not only used for ships, but also any submerged (underwater or underground) steel structure that is prone to corrosion.

Manufacturing sacrificial anodes can use indium metal at different purity grades, depending on the precise properties of the aluminum, or aluminum-zinc alloys used in the industry.

概述

Utilize the purity grade that best meets your need for the optimum alloy for corrosion protection.

Inhibiting corrosion is a delicate balance between inhibiting electrochemical processes and economical drivers like metal cost. Specific solution and alloy compositions allow for a wider range of input indium purities than typically seen in industrial applications. Our indium anodes are available to fit any desired impurity requirement that best meets your need.
