Microbiologically Influenced Corrosion (MIC):
-Recognition, Mitigation and Prevention


Course Outline |Who Should Attend |Registration |In-House |On-Demand |Online Courses |PPT Slides+Testbank |Course List

 Course Overview

Microbiologically influenced corrosion (MIC), also known as microbial corrosion or biological corrosion, is the deterioration of metals as a result of the metabolic activity of microorganisms. Many industries are known to be affected by MIC. This 5-day corrosion course aims to provide the participant with a thorough understanding of the causes of microbiologically influenced corrosion, its recognition, treatment, mitigation, testing and monitoring, and prevention. Upon completion of this corrosion short course the participants will be able to identify the different forms of corrosion damage caused by different types of bacteria, apply appropriate strategies and methods to treat and mitigate systems affected by MIC. Guidelines for the prevention of microbiologically influenced corrosion are also included in the course material.
This corrosion short course is available for in-house training, online and distance learning worldwide. It can also be customized to meet the specific needs of your organization.

Who Should Attend


Many industries and systems are known to be affected by MIC. This corrosion short course will benefit corrosion practitioners, designers, architects, technical managers, inspection and maintenance engineers, quality control personnel, facility owners and operators, and those involved in failure analysis.

  • Chemical processing industries: stainless steel tanks, pipelines and flanged joints, particularly in welded areas after hydrotesting with natural river or well waters.

  • Pharmaceutical industry: wastewater treatment facility

  • Nuclear power generation: carbon and stainless steel piping and tanks; copper-nickel, stainless, brass and aluminum bronze cooling water pipes and tubes, especially during construction, hydrotest, and outage periods.

  • Onshore and offshore oil and gas industries: mothballed and waterflood systems; oil and gas handling systems, particularly in those environments soured by sulfate reducing bacteria (SRB)-produced sulfides

  • Underground pipeline industry: water-saturated clay-type soils of near-neutral pH with decaying organic matter and a source of SRB.

  • Water treatment industry: heat exchangers and piping

  • Sewage handling and treatment industry: wastewater basin, tanks, piping, concrete and reinforced concrete structures

  • Highway maintenance industry: culvert piping

  • Aviation industry: aluminum integral wing tanks and fuel storage tanks

  • Metal working industry: increased wear from breakdown of machining oils and emulsions

  • Marine and shipping industry: accelerated low water corrosion (ALWC) of steel pilings, accelerated damage to ships and barges

  • Fire Protection Systems

  • Water and Gas distribution pipelines

Successful completion of this corrosion course helps participants prepare for their NACE certification examinations at the Corrosion Technician, Corrosion Technologist and Senior Corrosion Technologist levels.

 In-House Training Corrosion Courses


If you are concerned with corrosion in your business, in-house training is a great solution to train a group of employees from design, production, operation, quality assurance, inspection and maintenance, and technical sales and support on corrosion control and corrosion prevention technology. The contents of all corrosion courses can be customized to fit your organization's needs.


There is no minimum or maximum number of participants required for in-house training corrosion courses. We conduct the in-house training corrosion course at your company's premises and at a time convenient to your company. Requests for in-house training corrosion courses from overseas countries are also welcome.

 Corrosion Course-On-Demand


All our publicly scheduled corrosion short courses are conducted once a year. However, you do not need to wait for one year if you have missed any of the publicly scheduled corrosion courses as we have this unique corrosion course-on-demand scheme: we will conduct the course just for you on an one-on-one basis at a time and in a location convenient to you. This option costs significantly less than a full-scale in-house training program.


Click here to contact us for a quotation for taking this course as course-on-demand.


 Online and Distance Learning Corrosion Courses

All corrosion courses can be conducted through online or distance learning. An username and password will be emailed to course participants for accessing the online course materials. Alternatively, a CD-ROM containing the same online course material or a master hard copy of corrosion course notes can be sent to your organization. Instructions, course assignments, discussions and questions related to the corrosion courses are posted on the website. Free email support for online courses is provided for a period up to 12 months. A Certificate of Completion will be issued to participants who pass the online test with a score of 70% and above.

 PowerPoint Slides and Test Banks for Trainers, Instructors, Tutors, University Lecturers and Professors


If you are involved in teaching corrosion courses, you may wish to purchase a complete set of PowerPoint slides and the computerized test banks (in MicroTest format) with solutions. These presentations are suitable for teaching corrosion courses at different levels (from undergraduate to postgraduate) and durations (from 6 hrs to 40 hrs). These ready-to-use corrosion PowerPoint slides contain high quality color photographs, illustrations, animations and video clips. They can also be easily edited and customized to your own styles. The corrosion test banks contain over 1,000 corrosion questions for your use in tutorials, tests or examinations. These questions are conveniently grouped into 4 categories in the test bank: (1) true or false, (2) multiple choice, (3) calculation, and (4) reasoning and open-ended discussions).
