Biological Treatment of Microbial Corrosion

1. Introduction: Why corrosion and particularly microbial corrosion are important?

1.1. The definition of Engineering Importance as a function of "risk" and "cost",

1.2. What are the risks and costs of corrosion and microbial corrosion

1.2.1. Economical Costs

1.2.2. Ecological Costs

1.2.3. How can Risks, defined as a function of likelihood and consequences, be related to microbial corrosion.

2.1. The thermodynamics of corrosion and its importance in dealing with it in industries

2.2. Some basic concepts of corrosion, anodic and cathodic reactions, the role of electrolyte, why under real-life, industrial conditions the four requirements for making an electrochemical cell will be reduced to only three?

2.3. Introduction to "series" and "parallel" corrosion scenarios: why sometimes apparently full treatment of corrosion does not remove it and why by right treatment of one reaction, other reactions can also be controlled.

2.4. Corrosion treatment strategies: Use of chemicals, Cathodic/anodic protection, coatings, materials selection, design
