WHEN A FAILURE ANALYSIS IS PERFORMED?

A failure analysis is performed when a system, an equipment or a component is subjected to an early, sudden or unexpected failure.

The main principles of this analysis are applicable to any branch of manufacturing sector since the triggering factors can be divided in three specific classes:

  • Chemistry and microstructure of the material;
  • Manufacturing process parameters and operating conditions;
  • Influence of external factors such as aggressive environment and thermal or mechanical load conditions.

Corrective actions should be taken as soon as possible.

WHICH ARE THE FACTORS THAT BRING TO A PRODUCT’S FAILURE?

Traditionally, the failure of a component is associated with mechanical load, but this is only the final cause of the collapse.

There are some hints that allow to recognize the failure initiation before catastrophic rupture, such as:

  • Presence of defects such as porosity, inclusions, precipitates, impurities and surface cracks;
  • Under-paint corrosion, pit, ant nest corrosion, erosion-corrosion;
  • Degradation, change in crystallinity and degree of crosslinking;
  • Embrittlement, solvent attack, transparency or colour loss and crazing.

QUALITY CONTROL AND SUPPLIER VALIDATION

A critical step, in particular for plastics, is the quality control of input materials. Sometimes it is possible to find defects, non-conformities or deviations between the properties of materials belonging to different batches, or when the supplier is substituted.
