Following a brazing cycle performed on the braze material, a wear-resistant coating is formed in which the first particles are dispersed in a matrix of the braze alloy.Type: ApplicationFiled: December 15, 2011Publication date: June 20, 2013Applicant: GENERAL ELECTRIC COMPANYInventors: David Edwin Budinger, Jonathan Reid Biberstine

Patent number: 8465803Abstract: A self-replicating monolayer system employing polymerization of monomers or nanoparticle ensembles on a defined template provides synthesis of two-dimensional single molecule polymers. Systems of self-replicating monolayers are used as templates for growth of inorganic colloids. A preferred embodiment employs SAM-based replication, wherein an initial monolayer is patterned and used as a template for self-assembly of a second monolayer by molecular recognition. The second monolayer is polymerized in place and the monolayers are separated to form a replicate. Both may then function as templates for monolayer assemblies. A generic self-replicating monomer unit comprises a polymerizable moiety attached by methylene repeats to a recognition element and an ending unit that will not interfere with the chosen recognition chemistry. The recognition element is self-complementary, unless two replicating monomers with compatible cross-linking chemistry are employed.Type: GrantFiled: July 23, 2012Date of Patent: June 18, 2013Assignee: Massachusetts Institute of TechnologyInventors: Joseph M.
