5 einfache Techniken für Cathodic protection

Zinc can “rust” in water, but it is really corroding to a white color while the other metals do not rust or corrode.

It is observed that aluminum and zinc have potentials close to each other and magnesium has the most negative potential.

A very low resistance Struktur is required for a cathodic protection Organismus, and it must remain low hinein resistance over the life of the Gebilde.

In some cases, external power sources can Beryllium used to supply additional electrons to the electrochemical process, which can increase the effectiveness of cathodic protection.

Here, aluminum bars (or another suitable metal) are mounted directly on steel sections to assume the role of the sacrificial metal. Steel water heaters, tanks and piles are also cathodically protected using a similar method.

Basically, a zinc anode is designed to be the thing on your boat that corrodes instead of any steel or other metal components of your boat – like the engine and propeller.

An endless number of engine and pencil anodes are available, some common sizes listed below, other diameters/lengths/threads also available.

If an oxidizing component such as ferric ion is added to the solution, the corrosion potential can be calculated on the Evans diagram. This is done with the help Zinc anode of the principle of equality of oxidation and reduction current.

Availability: Traditionally used by the maritime industry, hence zinc anodes are widely available. See data sheet for zinc alloyed sacrificial anodes.

Galvanic CP can be produced by a galvanic or sacrificial Gebilde when limited amounts of current are needed, soil resistivity is low (normally less than 5,000 ohm/cm) and electric power is limited or not available.

If you are pregnant, nursing, taking any medication or have a medical condition, please consult your healthcare practitioner before taking any dietary supplement. Keep out of reach of children. Store in a Phatt, dry place. Do not use if outer bottle seal is missing, torn or damaged in any way.
