Series: ASM Failure Analysis Case Histories
Publisher: ASM International
Published: 01 June 2019
DOI: 10.31399/asm.fach.modes.c9001593
EISBN: 978-1-62708-234-1
.... The techniques utilized included scanning electron microscopy, Fourier transform infrared spectroscopy, differential scanning calorimetry, thermomechanical analysis, and melt flow rate determination. It was the conclusion of the investigation that the part failed via brittle fracture, with evidence also...

...Abstract Abstract Thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) were used to analyze an automotive polyoxymethylene (POM) sensor housing that was depolymerizing during service. It was found that a combination of heat, oxygen, and sulfuric acid attacked and caused...

... apparent in the results, suggestive of degradation of the failed part material. Differential scanning calorimetry was performed on the sleeve materials using a heat/cool/heat methodology. Testing of the reference material produced initial heating results indicative of a PBT resin, as illustrated...

..., and the obtained spectrum exhibited absorption bands characteristic of a polyacetal resin. It is significant to note that polyacetal copolymers and homopolymers cannot be differentiated spectrally, and a melting point determination is often used to distinguish between these materials. Differential scanning...
