Predicting the life expectancy of materials in systems

Predicting life expectancy is essential for the efficient and reliable operation of systems, particulalrly in extreme conditions such as high temperatures and pressures and with aggressive liquids and gases. Industries concerned include processing, automotive and aviation.

A system's efficiency can also deteriorate or fail in the operational phase. Analysis and prediction of the deterioration and failure behaviour provides essential information for product improvement. TNO is an independent institute with both broad and specialist knowledge in the area of materials, chemical and mechanical degradation in the mechanisms of materials, damage and failure behaviour of materials, tribology, material characterisation, processing methods and designs. Our unique experimental set-ups, state-of-the-art analysis equipment and advanced simulation models enable us to look at the performance and lifetime of systems in great detail. We thus go much further than engineering firms and testhouses.

Test methods

The life expectancy of materials in systems can be tested by a range of test methods like the Accelerated Lifetime Test (ALT) and the Multiple Environment Over Stress Test (MEOST). One such example is a test set-up that determines the life expectancy of a system affected by high temperatures, pressures and environmental components like hydrogen (H2), carbon monoxide (CO) and hydrogen sulphide (H2S). Testing this last is unique in the Benelux. Equipment like X-ray Diffraction (XRD) and the Scanning Electron Microscope (SEM) are used to analyse the degradation of materials. Analysis methods are frequently used in analysing cases of damage.
