Selecting Materials for Brazing a Honeycomb in Turbine Engines. To reduce leakage flows in turbo machines, tight operational clearances between stator and rotor parts are desirable. With reduced clearances, the risk of rub contact increases. In such situations, the stator is fitted with an abradable structure or coating that minimizes damage to.

FT8 honeycomb structure vacuum furnace brazing uses AMS4777 nickel-based brazing filler metal. The brazing filler metal is available in powder, paste, box and tape shapes. The presetting method of the brazing filler metal depends on the honeycomb sealing structure. The material state, the honeycomb core and the positioning method of the matrix.

Honeycomb-Seal Brazing By Dan Kay Figure 1 Figure 2 September 17, 2019 Question: We are brazing honeycomb for a turbine seal in an aircraft jet engine using nickel filler metal. The filler metal wicks up the nodes in the honeycomb during brazing, however, forming a hard crown-like surface on the top of each of the honeycomb cells.

The honeycomb sealing systems are produced by brazing together nickel-based superalloy sheets with a nickel-based brazing metal. This investigation aimed to generate data on the mechanical performance of Haynes 214 metal sheets brazed with the nickel-chromium-silicon filler metal BNi-5 (71 wt.% Ni, 19 wt.% Cr, 10 wt.% Si).

Two primary purposes for using honeycomb for rotor-blade tip seals (rubbing seals, abradable seals, etc.) are: (1) to provide a gas-path seal to prevent hot engine gases from getting around the ends of the turbine rotor blades, and (2) to simultaneously provide a sacrificial surface against which the rapidly rotating blades will rub.

Thus, the brazing process for honeycomb sandwich structure is very vital to prevent cracking, disjoining, and even destruction of the sandwich structure. For weight-sensitive applications, the metallic sandwich structures with low specific-strength have limited demand. In our design, high Nb containing TiAl (TAN) as face sheet and GH3536 nickel.
