Patent number: 7648605Abstract: A method of bonding an insulation layer (26) to a CMC layer (22) by applying a compliant joining layer (24) between them in a series of steps (52-70) effective to bond the layers (22, 24, 26) with reduced differential shrinkage stresses during firing and reduced residual stresses. The CMC layer (22) and the compliant layer (24) may each be fired to an intermediate stage prior to applying the next layer (24 and 26 respectively), such that the compliant layer (24) has a remaining amount of curing shrinkage between that of the CMC layer (22) and the insulating layer (26) during a final firing stage. The insulation layer (26) may be a friable graded insulation (26F) cast as a composite of hollow ceramic spheres (26S) in a ceramic matrix (26M). The compliant layer (24) may form a checkerboard of cracks (72) oriented generally perpendicular to the layer surface that function to relax stress.Type: GrantFiled: May 17, 2007Date of Patent: January 19, 2010Assignee: Siemens Energy, Inc.Inventors: Gary B. Merrill, Thomas B. Jackson

Publication number: 20090317622Abstract: A magnesium alloy composite material includes a magnesium alloy matrix, and a nanoparticle second phase material dispersed in the magnesium alloy matrix. The nanoparticle second phase material has an average particle size ranging from 1.0 nm to 100 nm. Preferably, the amount of the nanoparticle second phase material ranges from 0.05 wt % to 2.5 wt % based on total weight of the magnesium alloy composite material. With the addition of the nanoparticle second phase material to the magnesium alloy matrix, hardness can be increased to a relatively high level without significantly increasing density.Type: ApplicationFiled: January 13, 2009Publication date: December 24, 2009Inventors: Song-Jeng HUANG, Hui-Kan HSU, Tang-Hao CHIANG

Patent number: 7635515Abstract: A heterogeneous body having ceramic rich cermet regions in a more ductile metal matrix. The heterogeneous bodies are formed by thermal spray operations on metal substrates. The thermal spray operations apply heat to a cermet powder and project it onto a solid substrate. The cermet powder is composed of complex composite particles in which a complex ceramic-metallic core particle is coated with a matrix precursor. The cermet regions are generally comprised of complex ceramic-metallic composites that correspond approximately to the core particles. The cermet regions are approximately lenticular shaped with an average width that is at least approximately twice the average thickness. The cermet regions are imbedded within the matrix phase and generally isolated from one another. They have obverse and reverse surfaces. The matrix phase is formed from the matrix precursor coating on the core particles.Type: GrantFiled: April 6, 2005Date of Patent: December 22, 2009Assignee: Powdermet, IncInventor: Andrew J. Sherman
