Publication number: 20190203144Abstract: Methods are provided for lubricating oxygenated diamond-like carbon surfaces to reduce friction while reducing or minimizing wear on the surface. A diamond-like carbon surface layer having a surface ratio of oxygen to carbon of 1:15 or more can be lubricated using a lubricant oil that includes a molybdenum-based friction modifier additive, a tungsten-based friction modifier additive, or a combination thereof. The Mo-based friction modifier (and/or other friction modifier based on a Group VI metal) can be selected based on the Gibbs free energy of adsorption (?G) for the friction modifier on an oxygenated diamond-like carbon surface. Use of a Group VI metal-based friction modifier having a ?G of adsorption with a sufficiently large magnitude can reduce friction at the surface of the oxygenated diamond-like carbon while causing a reduced or minimized amount of wear during lubrication.Type: ApplicationFiled: December 3, 2018Publication date: July 4, 2019Inventors: Arben JUSUFI, Alan M.

Patent number: 8676543Abstract: Mechanical oscillators employ the use of resonance parameters, frequency and the quality factor Q, for the measurement of corrosion or deposition. The ability of a mechanical oscillator to measure small amounts of metal loss or deposition is not only dependent upon the mechanical design but is limited by the precision in determining the resonance frequency and Q. Methods for measuring these resonance parameters with a high precision in the presence of noise are provided. The increased degree of precision improves the utility of these devices as sensitive probes for corrosion and deposition (fouling) measurement. The increased degree of precision is enabled in part by employing curve fitting consistent with modeling the mechanical oscillator as a simple harmonic oscillator. This curve fitting procedure, combined with averaging and utilizing signal processing parameters to mitigate noise effects, adds precision in measuring resonance parameters.Type: GrantFiled: June 2, 2010Date of Patent: March 18, 2014Assignee: ExxonMobil Research and Engineering CompanyInventors: H.

Publication number: 20100324852Abstract: The prior art describes the application of mechanical oscillators for the measurement of corrosion and/or deposition. Mechanical oscillators employ the use of resonance parameters, frequency and the quality factor Q, for the measurement of corrosion or deposition. However, the prior art does not consider the required precision for measuring frequency or Q in the presence of noise to make these measurements. In particular, the ability of the mechanical oscillator to measure small amounts of metal loss or deposition is not only dependent upon the mechanical design but is limited by the precision in determining the resonance frequency and Q. The present invention discloses methods for measuring these resonance parameters with a high precision in the presence of noise. This degree of precision is required to maximize the utility of these devices as sensitive probes for corrosion and deposition (fouling) measurement.Type: ApplicationFiled: June 2, 2010Publication date: December 23, 2010Applicant: EXXONMOBIL RESEARCH AND ENGINEERING COMPANYInventors: H.
