Materials Degradation in Mechanical Design: Wear, Corrosion, Fatigue and their Interactions
I.D. # WB1722 Duration 10 Hours
Materials degradation from environmental conditions is a common factor that will often occur in mechanical equipment used in every type of environment. These processes can frequently materialize in unpredicted and harmful ways, especially when they interact and lead to early component damage or failure.


This five-session course will summarize the mechanisms that cause materials and mechanical components to degrade in service through exposure to deleterious mechanical and environmental conditions. The course is designed to develop knowledge of issues of material degradation in service and the effect upon the performance and reliability in the process of mechanical design. These processes include wear, corrosion, fatigue, and their interactions. The instructor will take a practical approach to the topics to allow participants to cite the causes of performance reduction. Potential solutions will be covered including material selection and material or design modifications that would improve component life and performance in a range of harmful environments or operating conditions. The review of each mechanism will include a presentation of the fundamental basis for these failure mechanisms, followed by practical examples of how they occur in reality.


Learning Objectives
By participating in this web seminar, you should be able to:

  • Cite the typical wear mechanisms that occur in mechanical equipment and their causes

  • Cite the basic corrosion mechanisms and their causes

  • Identify the interactions that occur between wear, corrosion and fatigue

  • Suggest practical material or design solutions to those damage mechanisms


Who Should Attend
Engineers who design and process mechanical equipment; applications engineers involved in equipment or component design specific to an industrial application; materials, process and equipment development engineers; plant engineers; test engineers responsible for product or component testing and analysis of failed mechanisms; and quality engineers who establish methods and procedures for component reliability and analysis of failed components will benefit most from this course.
