Failure analysis and prevention
Failure analysis is not just about a broken or cracked component. Failures can manifest from mechanical loading, corrosion, wear (sliding wear, erosion), thermal effects, electrical loading, etc. Low manufacturing yields are also a type of failure. This is a multidisciplinary process which considers the design, operating environment, materials, and manufacturing process. With our background in materials science, mechanical engineering, and chemistry, we can work with your organization to identify root cause for a failure. Understanding failure mechanisms is key to success. These are team projects. The process can be formalized by several methods. We are most familiar with the fault tree and Ishikawa diagram approaches. The following sections describe in more detail our experience in corrosion, wear (tribology) and fracture.
