The wear mechanism was studied through worn surfaces and microscopic examination of the developed wear tracks.
Microscopic examination of the surface of the alumina substrate bonded to the BG resin composite revealed that the failure occurred at the bulk of the material, with residue of the veneering composite remaining on the core.
Over the last 10 years, with the introduction of perfluorcarbon/osmium fixation, detailed transmission electron microscopic examination of airway surface liquid has revealed at least two layers of mucus.
The Plasma Nitride (PN) treated surface has been characterized by Vickers microhardness measurements, Scanning Electron Microscopic (SEM) examination, X-ray Diffraction (XRD) and sliding wear assessment.
Microscopic examination of the failure surfaces shows that delamination occurs through fiber/matrix interfacial debonding, and some shear failure of the matrix in resin-rich areas.
Microscopic examination of the fracture surfaces of the foam with large cells tested at low crosshead rates revealed craze-like deformation of the solid polymer in cell edges.
Microscopic examination of the fracture surfaces from the cycled samples showed clear de-bonding of the sulfur from the aggregate whereas it was seen adhering in those non-cycled.
Fraud cannot be ruled out, they said, though the cursive style of the script and a microscopic examination of the etched surface seemed to diminish suspicions.
Galvanostatic and potentiostatic techniques, and microscopic examination of the metal surface, including scanning electron microscopy, were employed.
A microscopic examination of the fracture surface reveals toughening mechanisms such as particle pull out, crack front roughening and crack bridging.
