Materials Degradation in Mechanical Design: Wear, Corrosion, Fatigue and their Interactions Web Seminar RePlay

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.

Captured from five, two-hour sessions, this course summarizes the mechanisms that cause materials and mechanical components to degrade in service through exposure to deleterious mechanical and environmental conditions. It’s 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 takes a practical approach and covers potential solutions, including material selection and material or design modifications that improve component life and performance in a range of harmful environments or operating conditions. The review of each mechanism includes a presentation of the fundamental basis for these failure mechanisms, followed by practical examples of how they occur in reality.

What Will You Learn

By participating in this course, you'll 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
