  • Patent number: 11686001
    Abstract: The disclosure provides a eutectic ceramic thermal barrier material and a preparation method thereof, which relates to the field of composite materials. The present disclosure provides a eutectic ceramic thermal barrier material comprising a nickel-based superalloy substrate, an intermediate binding layer and a eutectic ceramic cladding layer stacked sequentially; the intermediate binding layer comprises a NiCoCrAlY binding layer; the eutectic ceramic cladding layer comprises an Al2O3/GdAlO3 binary eutectic ceramic coating or an Al2O3/GdAlO3/ZrO2 ternary eutectic ceramic coating. The eutectic ceramic thermal barrier material provided by the present disclosure has good high temperature resistance, good oxidation resistance and excellent mechanical properties.

  • Patent number: 8762557
    Abstract: A signaling gateway (SG) and a method for the SG to process signaling. The method comprises: after a SG which is configured with SCCP protocol, one or more SCCP service related subsystems, and GT translation function receives a connectionless-oriented SCCP service message in MTP3 protocol, the SG determining whether the message is a local office message according to a destination signaling point code carried in the message or a signaling point code generated by translating a GT carried in the message; and if the message is a local office message, the SG forwarding the message to a corresponding SCCP service related subsystem configured in the SG according to a subsystem number carried in the message, or forwarding the message to a corresponding SCCP service related subsystem configured in a MGC; the MGC and SG having the same signaling point code and being connected in the M3UA protocol.
