Biological Corrosion Characteristics

Biological corrosion is the process of destruction of metals under the influence of living organisms (algae, bacteria, fungus). Therefore, microorganisms which live in the soil or in the air can significantly affect the corrosion processes.

Protection from the Underground Metal Corrosion

Corrosion attack is the metal “disease” which is much more complicated and economically difficult to cure than to choose the correct method of protection against the metal corrosion in advance.

When choosing the protection method, it is important to consider all the environmental factors which affect the “wellbeing” of metal object.

Equipment for the Electrochemical Protection against Corrosion

Electrochemical protection is the cathodic defense technique that works with deliberate metal destruction, and anodic defense technique that works with electrode potential moving into the direction of the range of values.

Cathodic Protection of Metals

Cathodic protection is the electrochemical protection which is based on the application of current.

In the field of manufacturing, generally, one or two types of such protection are used.

Means of electrochemical protection of metals

МMethods and means of metal protection against corrosion could be divided into four separate categories:

1.Protection through the changes in the environment.
2. Electrochemical protection.
3.Protective coating.
4.Alloying.

Let us examine one of these methods, particularly, electrochemical protection.

Graphiteplastics: Properties and Scope of Use

ГGraphiteplastics is the plastic product which contains the filling of graphite or any other carbonized substance (coke, thermoanthracite). Phenolic resins, Polyamides, Fluorine etc. usually serve as binding substances.
