Innovative Solution for:

Corrosion of iron and steel

Innovative solution for structural corrosion resistance.

A technique for corrosion resistance on large structures is to have sacraficial material that will corrode and wear away, but will not rust the structure. This application is used in corrosion resistance in Gas pipelines. The concept works by sacrificing a material in Galvanic corrosion. The sacrificial material is called the anode material, the structure becomes the cathode. By placing the anode material across sections of the structure, the sacrifical material will corrode away. Every so often the anode material will need to be changed out, thus making the material expendable. By corroding out the expendable material, the structure itself will have an extended life.
