Magnet Component Failure Investigation
The metallurgical laboratory solved a magnet de-bonding issue.
Investigating component failure is an example of the metallurgy testing and consultancy expertise offered by Intertek. The client asked Intertek to investigate a failed rotor assembly that failed due to de-bonding of two of the magnets from the internal magnet array. Visual low power microscope analysis clearly showed limited surface coverage of the adhesive in the failed rotor, and the shape of the adhesive was unfavourable. The rotor contained a large central defect, which can promote debonding by mechanisms such as stress raising and/or environmental factors i.e. liquid penetration. The colour of the adhesives also varied.
