Surface Characterization Methods—XPS, TOF-SIMS, and SAM A Complimentary Ensemble of Tools

Autor: J. E. deVries

Publikováno v: Journal of Materials Engineering and Performance. 7:303-311

X-ray photoelectron spectroscopy (XPS), time-of-flight secondary ion mass spectrometry (TOF-SIMS), and scanning auger microscopy (SAM) analytical techniques have played important roles in the characterization of the surface and the interfacial chemis

Characterization of films formed at a lubricated cam/tappet contact

Autor: P.J. Schmitz, P. A. Willermet, J. E. deVries, L. P. Haack, R.O. Carter, N. E. Lindsay, R.E. Chase

Publikováno v: Spectrochimica Acta Part A: Molecular Spectroscopy. 49:2057-2070

The surfaces of tappet inserts subjected to lubricated, moving contact in a cam/tappet friction apparatus have been analyzed by IR reflection—absorption, X-ray photoelectron and Auger electron spectroscopies. The two lubricants used were similar fu

XPS mapping technique for the identification of adhesion loss mechanisms

Autor: S. L. Kaberline, Larry P. Haack, Ray A. Dickie, J. E. deVries, M. A. DeBolt

Publikováno v: Surface and Interface Analysis. 20:115-120

An x-ray photoelectron spectroscopy (XPS) mapping technique was developed to define spatially the interfacial chemistry of adhesive-adherent debonding. The technique was used to identify mechanisms of corrosion-induced bond failure for an epoxy adhes

Definition of Molecular Configuration by the Use of π* ← π Shakeup Satellites in the X-Ray Photoelectron Spectra of Oxygen-Bridged Dinuclear Copper(II) Complexes

Autor: Ray A. Dickie, Walter O. Siegl, J. E. deVries

Publikováno v: Analytical Sciences. 9:89-94

X-Ray photoelectron spectoscopy has been used to study the structure and bonding of Binuclear oxygen-bridged copper(II) complexes. The aromatic onstituency of the complexes gives rise to π*←π shakeup satellites in the spectra of the ring carbons

Publikováno v: Journal of Tribology. 113:38-47

The frictional behavior of two oils was measured in a cam/tappet friction apparatus using a direct acting bucket tappet geometry. One oil contained a soluble molybdenum friction modifier. The tappet was equipped with a removable friction disk, which

Interfacial chemistry of corrosion-induced bond degradation for epoxy/dicyandiamide adhesive bonded to cold-rolled and galvanized steels

Autor: Joseph W. Holubka, J. E. deVries, Ray A. Dickie

Publikováno v: Journal of Adhesion Science and Technology. 4:57-67

The interfacial chemistry of a conventional epoxy/dicyandiamide adhesive formulation applied to cold-rolled and galvanized steels has been studied by X-ray photoelectron spectroscopy (XPS). In both cases, the interfacial corrosion process appears to
