Types of corrosion/Corrosion removal

According to chemically free enthalpy as described in thermodynamics, it is the goal of every material to revert to its subordinate accidental state. That means it wants to revert to its component parts. In the case of unalloyed steel this means that it will revert to iron oxide, from which it was originally formed with the help of a lot of energy. If unalloyed steel is left without protection in a humid environment for a longer period of time, then the iron will eventually be completely disintegrated.

It is not intended to discuss each individual type of corrosion in detail here, but to refer to literature sources. However, it is a fact that even special stainless steels (SS) can be severely damaged by corrosion if used incorrectly. Besides the correct choice of materialsand professional fabrication, an adequate (corrosion preventive) construction is also of paramount importance. If the right corrosion related  construction were chosen, which took into account and applied the available knowledge of corrosion and corrosion protection, billions of dollarsworth of corrosion damage worldwide could be avoided every year. Please refer to the literature sources for further information.

Corrosive products can severely contaminate components/systems, can lead to a functional breakdown and can also cause grave product contamination. Removing corrosive layers and products can therefore be a very important responsibility.

Corrosive layers and particles can only be removed using special suitable solutions. In order to identify the correct agent and the right method of treatment it is very important to carry out certain preliminary clarifications. Both the intensity of the attack (propagation of corrosion) and the type of attack (corrosion type) need to be analysed as accurately as possible in preliminary . By providing the laboratory with an original component part of a plant or system,  it will  be possible  to determine the most suitable solution. Here  it is also important to find the most effective, but not too aggressive medium, to prevent the  attack of the base material. It is essential to be highly  experienced and to find a highly effective solution. The optimal solution can be offered together with the specific treatment techniques /processes.
