Simple SummaryContent extracted from patent full text and abstract with AI.

This patent presents a germanium-containing, nickel-based solder alloy designed for high-temperature applications, especially for joining nickel- or cobalt-based superalloy components such as those found in gas turbines. By incorporating germanium, the solder reduces harmful brittle phases and oxidation, allowing improved performance when soldering advanced materials used in turbine blades and combustion chamber elements.

Use CasesContent extracted from patent full text and abstract with AI.

  • Repair and joining of gas turbine blades and vanes made from nickel- or cobalt-based superalloys
  • Manufacturing and refurbishment of high-performance turbine components exposed to extreme temperatures, such as combustion chambers
  • Soldering processes in aerospace, energy generation, and industrial turbomachinery sectors
  • Improved fabrication or repair of single-crystal or directionally solidified superalloy parts

BenefitsContent extracted from patent full text and abstract with AI.

  • Reduces formation of brittle phases and improves mechanical toughness where solder is applied
  • Germanium addition lessens oxidation and simplifies processing compared to traditional boron- or silicon-based solders
  • Enables reliable joining of advanced superalloys while maintaining high temperature resistance
  • Allows more efficient repairs and longer life for turbine and high-temperature engine components
  • Supports both nickel- and cobalt-based superalloy substrates, increasing versatility in application
  • Facilitates isothermal soldering and potentially faster processing due to enhanced germanium diffusion properties
