  • CONNECTION PERFORMANCE UNIFORMITY IMPROVING METHOD FOR ASSEMBLY JOINT SURFACE BASED ON PARTITION HARDENING
    Publication number: 20220275473
    Abstract: A method for improving the uniformity of connection performance of an assembly surface based on zoned hardening is provided. Through a finite element contact analysis of the assembly surface, a topology optimization of the hardening layer layout of the assembly surface is carried out with the aim of improving the uniformity of the connection performance of the assembly surface. The design is based on the optimized theoretical data, and uses the laser hardening technology to realize the zoned differential hardening of the assembly surface. By performing the zoned differential hardening on the assembly surface, the uniformity of the connection performance of the assembly surface can be effectively improved, and the purpose of improving the high cycle fatigue and the vibration of the high-end equipment parts such as aero-engines can be further achieved.

  • Low thermal conductivity misfit layer compounds with layer to layer disorder
    Patent number: 8545991
    Abstract: Compositions comprise an alternating plurality of ordered layers of a first composition MX and a second composition TX2, wherein M is one of Sn, Pb, Sb, Bi, or a rare earth metal, X is S or Se and T is Ti, V, Cr, Nb, or Ta. In some examples, the alternating plurality of ordered layers conforms to a substrate. In typical examples, each of the ordered layers of the first composition has a common thickness and/or each of the ordered layers of the first material has a common composition. In some examples, each of the ordered layers of the second composition has a common thickness and/or a common composition.
