NOTE: The author seems to be describing the DS power steering piston and rod, on which the piston is in the middle of the rod. The SM's steering cylinder has the piston on the end of the rod, which rod's cross-sectional area is half the area of the other side of the piston. Full hydraulic pressure is admitted to the rod side at all times while ...

Power steering is a system for reducing a driver's effort to turn a steering wheel of a motor vehicle, by using a power source to assist steering. [1]Hydraulic or electric actuators add controlled energy to the steering mechanism, so the driver can provide less effort to turn the steered wheels when driving at typical speeds, and considerably reduce the physical effort necessary to turn the ...
The system is fully regenerative: all of the engine's power reaches the track either through the main driveshaft or the steering system; none of the energy is being lost to brakes or clutches. Additionally, since power is fed around the transmission to the steering system, in some designs the tank can be turned or even pivoted in place even ...
In this case, sacrificial anodes work as part of a galvanic couple, promoting corrosion of the anode, while protecting the cathode metal. In other cases, such as mixed metals in piping (for example, copper, cast iron and other cast metals), galvanic corrosion will contribute to accelerated corrosion of parts of the system.
A galvanic anode, or sacrificial anode, is the main component of a galvanic cathodic protection system used to protect buried or submerged metal structures from corrosion. They are made from a metal alloy with a more "active" voltage (more negative reduction potential / more positive oxidation potential ) than the metal of the structure.

The driving power for pitting corrosion is the depassivation of a small area, which becomes anodic (oxidation reaction) while an unknown but potentially vast area becomes cathodic (reduction reaction), leading to very localized galvanic corrosion. The corrosion penetrates the mass of the metal, with a limited diffusion of ions.
