Process for cathodic protection against corrosion of steel diving bottles

摘要

Process for cathodic protection against corrosion in an aqueous medium of the walls of a steel diving bottle intended to contain a gas for breathing. According to the invention a sacrificial electrode in the form of a bead 8 of a pure metal or in the form of alloy is placed inside the said bottle, so as to bring the steel constituting the casing of the bottle into the so-called "immunity" zone. <IMAGE>
