  • Patent number: 10017872
    Abstract: The embodiments described herein relate to anodic films and methods for forming anodic films. The methods described can be used to form anodic films that have a white appearance. Methods involve positioning reflective particles on or within a substrate prior to or during an anodizing process. The reflective particles are positioned within the metal oxide of the resultant anodic film but substantially outside the pores of the anodic film. The reflective particles scatter incident light giving the resultant anodic film a white appearance.

  • Patent number: 9951630
    Abstract: The present inventions incorporate self-healing mechanisms into current and future EBC systems. Such approaches have the potential to form environmental protection materials (i.e. thermally grown silicate compositions) in-situ to enable the ability to provide environmental protection to SiC based ceramics even in the event that cracks or voids form from within the EBC layer. In this disclosure, novel, self-healing EBC systems are disclosed along with coating synthesis techniques required to deposit the materials, microstructures and architectures. This research is anticipated to result in a thermal/environmental barrier coating system (T/EBC) that provides improved durability over current coatings. These advancements will aid the use of Si-based ceramics in a range of high temperature applications such a gas turbine engines and heat exchangers. These advances will not only benefit military engines, but also commercial and industrial engines requiring greater performance.
