  • Publication number: 20090050478
    Abstract: The corrosion inhibiting activity of a coating is determined from the effect of corrosion inhibiting species released by the coating on the oxygen reduction current for a cathode placed very close to the coating. A rotating disk electrode or pumped solution flow is used to sweep the corrosion inhibiting species from the coating surface to the cathode. The oxygen reduction current is measured under conditions of oxygen diffusion control.

  • Patent number: 7459102
    Abstract: A corrosion inhibitor that includes several oxo-anion compositions useful for preventing the propagation of pit corrosion on aluminum and aluminum alloys. The oxo-anion compositions may include soluble polymeric oxidic acids comprising combinations of molybdenum, phosphorous, tungsten, and silicon. These compositions are useful as corrosion inhibitors in high-moisture, corrosive environments, such as radiators and cooling systems. For low-moisture environments, these oxo-anion compositions can be reacted with a counter-ion, such as various metals, including, but not limited to the rear earth metals, to form a soluble salt. The salt can then be adsorbed onto a carrier, such as paint pigments, which can then be applied to the surfaces of aluminum and aluminum alloys. These surface adsorbates then become sparingly soluble and are gradually released over time in the presence of an aqueous corrosive agent so as to prevent propagation of pit corrosion.

  • Publication number: 20080258114
    Abstract: A pigment grade corrosion inhibitor and a method of applying the inhibitor is disclosed. The inhibitor is comprised of a host species comprised of an inorganic compound having a layered structure and a guest species comprised an anionic species of a weak acid. The host species is preferably a double hydroxide having a structure of: [M(II)1-x M(III)x (OH?)2] [An?x/n·y H2O], where M(II) is a divalent metal cationic species, M(III) is a trivalent metal cationic species, and An? is an anionic species, preferably with the species present in a range of: 0.2?M(III)/(M(II)+M(III))?0.4. The guest species include: various phosphoric acids and derivatives thereof; boric acid; cyanamidic acid; nitrous acid; derivatives of thio- and dithiocarbonic acid; thio-organic compounds functionalized with at least one —SH group of acidic character, including: 2,5-dimercapto-1,3,4-thiadiazole (DMTD), 2,4-dimercapto-s-triazolo-[4,3-b]-1,3-4 thiadiazole, trithiocyanuric acid (TMT), and dithiocyanuric acid.

  • Publication number: 20080241932
    Abstract: Electrochemical devices, methods, and systems for detecting and quantifying analytes are disclosed. A chemical detection reagent is locally generated in a test solution by electrochemical reaction of a precursor compound caused to migrate into the test solution from a precursor solution separated from the test solution by a cell separator. This approach provides precise metering of the reagent, via the charge passed, and avoids the need to store a reagent solution that may be chemically unstable. In one embodiment, the starch concentration in a colloidal solution can be measured via spectroscopic detection of a blue complex formed by the interaction of starch with iodine produced, on demand, by electrochemical oxidation of iodide ion. The approach may also be used to characterize certain types of analytes. The invention is amenable to automation and is particularly useful for on-line monitoring of production processes, including the inclusion of feed back loop mechanisms for process control.

  • Patent number: 7328604
    Abstract: A microelectromechanical (MEM) fluid health sensing device comprises a viscosity sensor which provides an output that varies with the viscosity of a fluid in which it is immersed, and at least one other sensor which provides an output that varies with another predetermined parameter of the fluid. The viscosity sensor is preferably a MEM device fabricated by means of a “deep etch” process. The sensors are preferably integrated together on a common substrate, though they might also be fabricated separately and packaged together to form a hybrid device. A data processing means may be included which receives the sensor outputs and provides one or more outputs indicative of the health of the fluid. Sensor types which may be part of the present device include, for example, a temperature sensor, a MEM electrochemical sensor, a MEM accelerometer, a MEM contact switch lubricity sensor, and/or an inductive metallic wear sensor.

  • Patent number: 7027937
    Abstract: Methods, systems, and articles of manufacture consistent with the present invention provide for determining the environmental resistance of a wire insulation. The broadband impedance of the wire is obtained before and after the wire is exposed to an environmental condition. The real and imaginary components of the dielectric functions are then extracted from the broadband impedances. A tangent of a ratio of the imaginary component to the real component of the dielectric function of the wire prior to exposure is compared to a tangent of a ratio of the imaginary component to the real component of the dielectric function of the wire after to exposure. The two tangents are then compared to determine the environmental resistant of the insulation.

  • Patent number: 6942899
    Abstract: A film which may be placed on a metallic substrate to inhibit corrosion of the substrate when in a corrosive environment. The film also inhibits corrosion at a defect area in the film when the substrate is exposed in the presence of a corrosive environment. The film includes dopants which release from the film when corrosion begins at a film defect. Therefore, the film not only inhibits corrosion where the film is undamaged, but also inhibits corrosion at the site of a defect in the film. Advantageously, the system does not lose its effectiveness over a given period of time if no defect occurs in the substrate.

  • Patent number: 6579472
    Abstract: An anti-corrosive sol-gel that is a combination of an organometallic salt, an organosilane, and a borate, phosphate, or zinc functional component.

The organosilane may also be selected from a large group of equivalent compounds, but is preferably 3-glycidoxypropyltrimethoxysilane (GTMS). Combination of the components takes place in the presence of an organic catalyst, preferably acetic acid.

  • Patent number: 6483319
    Abstract: A broadband test procedure detects the onset of stator winding insulation damage, identifies the failure mechanism, determines the winding's susceptibility to further damage, and predicts stator winding failure. This is accomplished by realizing that changes in the stator winding insulation and/or geometry are reflected as changes in the capacitance between the individual windings and, hence, as changes in the stator winding's broadband impedance response. In the currently preferred approach, the impedance response includes the frequency, magnitude, width, and phase of the resonant impedance.
