Patent number: 9429533Abstract: A hard, transparent coating for a substrate and associated method for coating is disclosed. The coating includes alternating layers of a soft coating and a hard coating. The coating further includes a sensor. The electrical resistivity of the sensor may be measured to determine if the coating has been degraded. The coating may further include a hydrophobic outer layer.Type: GrantFiled: July 9, 2014Date of Patent: August 30, 2016Assignee: The Boeing CompanyInventors: Kjersta L. Larson-Smith, Vasan S.

Patent number: 9403992Abstract: An exemplary embodiment provides coated polymeric substrates that have a polymeric substrate body with a coated surface. The surface coating includes more than one pair of coating layers. Each pair of coating layers includes a first applied coating layer and a second applied coating layer. In addition, an indicator, applied on top of or between coating layers, provides an indication of wear of the coating. The first and second applied coating layers have a thickness between about 3 to about 10 nanometers. The coating exhibits a Hall-Petch effect.Type: GrantFiled: November 13, 2013Date of Patent: August 2, 2016Assignee: The Boeing CompanyInventors: Kjersta L. Larson-Smith, Shawn M. Pare, Vasan S.

Patent number: 8962753Abstract: A hybrid coating composition including an organosilane component, a metal alkoxide component and a surfactant component, with the metal alkoxide component present in the composition at a molar ratio of about 75:1 with respect to the surfactant component. The hybrid coating composition once cured on a transparent substrate has an initial clarity greater than 98. Transparent members are also disclosed that include a transparent substrate having the hybrid coating composition cured on a first major surface thereof.Type: GrantFiled: March 12, 2014Date of Patent: February 24, 2015Assignee: The Boeing CompanyInventors: Kjersta L.

Patent number: 8932737Abstract: A coating and associated method for coating is disclosed. The coating provides a hard, transparent, UV blocking coating for a substrate. A UV blocking layer is first deposited upon the substrate, and a hard coating is deposited above the UV blocking layer. A soft coating layer may be deposited between the UV blocking layer and the hard coating. The soft and hard coating layers may both have the general composition SiOxCy. the soft and hard coating layers may be deposited by a plasma vapor deposition process.Type: GrantFiled: February 12, 2014Date of Patent: January 13, 2015Assignee: The Boeing CompanyInventors: David A.
