Engine Corrosion and Corrosion Prevention

Corrosion and corrosion prevention all have maintenance challenges and associated costs. The cost of preventative maintenance (which includes equipment), the cost of repair/overhaul and the potential cost of engine component mechanical breakdown that is due to corrosion. Ultimately, the benefits of having an intimate understanding of how corrosion occurs can lead to the correct decision making when participating in corrosion prevention measures. This paper will focus on the different types of operating environment, the types of internal and external corrosion, the materials and coatings used, the documented effects of good versus poor maintenance practices and the dispelling of some of the myths regarding maintenance philosophies in the different operational environments.
