Definition - What does Chemical Attack mean?
This is a form of deterioration or degradation of a material or structure due to its reaction with highly reactive substances such as liquids and gases. It is associated with the changing of the chemical characteristics or design of a structural surface when it forms a new layer of a strange material.
It is used to describe the type of corrosion that affects the durability and performance of substrates.
Corrosionpedia explains Chemical Attack
Chemical attack is a common issue in the industries that utilize metals. Any substance that reacts with the basic material of a structure yields a chemical attack. The most common are micro- organisms and acids. Moisture, temperature, and salts are key initiators of rusting; rusting is mostly associated with chemical attacks, and it’s a common issue in metallic components.
Chemically, oxidation and reduction reactions are the hidden processes that define a chemical attack. Lubrication and system oils facilitate the conditions necessary for chemical attack; that’s why additives are used to inhibit this attack on the surfaces they are in contact with. The construction industry suffers from concrete chemical attack, which is a potential threat to the stability of any building.
The type of chemical attack detected will help in judging the right coating or painting solution. Therefore, the surrounding environmental conditions will determine the presence of this form of corrosion agent.
