Patent number: 7833331Abstract: Corrosion-inhibiting pigments based on cobalt are described that contain a trivalent or tetravalent cobalt/valence stabilizer complex. An inorganic or organic material is used to stabilize the trivalent or tetravalent cobalt ion to form a compound that is sparingly soluble in water. Specific stabilizers are chosen to control the release rate of trivalent or tetravalent cobalt during exposure to water and to tailor the compatibility of the powder when used as a pigment in a chosen binder system. Stabilizers may also modify the processing and handling characteristics of the formed powders. Cobalt/valence stabilizer combinations are chosen based on the well-founded principles of cobalt coordination chemistry. Many cobalt-valence stabilizer combinations are presented that can equal the performance of conventional hexavalent chromium systems.Type: GrantFiled: August 2, 2007Date of Patent: November 16, 2010Assignee: University of DaytonInventors: Jeffrey Allen Sturgill, Andrew Wells Phelps, Joseph Thomas Swartzbaugh

Patent number: 7789958Abstract: Corrosion-inhibiting pigments based on manganese are described that contain a trivalent or tetravalent manganese/valence stabilizer complex. An inorganic or organic material is used to stabilize the trivalent or tetravalent manganese ion to form a compound that is sparingly soluble, exhibits low solubility, or is insoluble in water, depending upon the intended usage. Specific stabilizers are chosen to control the release rate of trivalent or tetravalent manganese during exposure to water and to tailor the compatibility of the powder when used as a pigment in a chosen binder system. Stabilizers may also modify the processing and handling characteristics of the formed powders. Manganese/valence stabilizer combinations are chosen based on the well-founded principles of manganese coordination chemistry. Many manganese-valence stabilizer combinations are presented that can equal the performance of conventional hexavalent chromium or tetravalent lead systems.Type: GrantFiled: January 4, 2007Date of Patent: September 7, 2010Assignee: University of DaytonInventors: Jeffrey A.
