First Number of "Payame Mohafezan" was published:

One of the most significant approaches to enhance the knowledge in corrosion science is to raise the public awareness by professional experts. The fervent motivation to write this periodical is to publish the acquired experience in divers fields of corrosion science specially water and steam processes.

Microbial corrosion of an iron key in the presence of Desulfovibrio ferrophilus strain IS5 (1 to 3) and corrosion under sterile (control) conditions (4 to 6). Both incubations were performed in artificial seawater medium at pH 7.3 and without addition of organic substrates (lithotrophic medium). Bar, 1 cm.
(1 to 3) Electrical microbially influenced corrosion (EMIC) of the first key led to 80.3% (2.7 g) Iron weight loss during 9 months
(4 to 6) Abiotic corrosion of another key in sterile medium during 27 months formed minimal corrosion products and led to 2.9% (0.09 g) iron weight loss

Microbiological corrosion or microbially induced corrosion (MIC) refers to corrosion and ensuing loss of metal caused by biological organisms. MIC can occur in any aqueous environments, and because of the omni present nature of microbes in fluid systems, MIC is a commonly occurring phenomenon. MIC is a common problem in industrial processes due to the presence of microbes, adequate nutrients and corrosive byproducts.
Biological organisms present in the aqueous medium often have the potential to increase or decrease oxygen transport to the surface; consequently, these organisms have a role in increasing or decreasing general corrosion.
Biological organisms fall under two groups based on the type of corrosion they engender: (a) Anaerobic corrosion (b) aerobic corrosion. Sulfate reducing bacteria (SRB) from the genera desulfovibrio are a typical example of anaerobic MIC. Aerobic sulfur oxidizing bacteria of the type thiobacillus can create an environment of up to 10 percent sulfuric acid, thereby encouraging rapid corrosion.

What is dealloying corrosion? Dealloying or selective leaching refers to the selective removal of one element from an alloy by corrosion processes. The potential difference between the alloying elements is the driving force for the preferential attack on the more "active" element in the alloy.

How to prevent dealloying? Dealloying, selective leaching and graphitic corrosion can be prevented through the following methods:
• Select metals/alloys that are more resistant to dealloying. For example, inhibited brass is more resistant to dezincification than alpha brass; ductile iron is more resistant to graphitic corrosion than gray cast iron.
• Control the environment to minimize the selective leaching
• Use sacrificial anode cathodic protection or impressed current cathodic protection
