Description du projet/ Project
Description
Optimization of the process of brazing
alloys for joining different aerospace
alloys used in gas turbine engines.
Characterization of the brazed joints;
the main goal being to develop
structural joints and characterize their
mechanical properties.
Objectifs/ Objectives
1) Understand the brazing process of
several alloys (Ni/B, Au/Cu, Ag, etc) as
a sealing and structural filler metal
and optimize it using brazing parameters
established in the laboratory.
2) Optimization of brazed joints made
with aerospace alloys in order to
understand the influence of the brazing
process basic conditions and achieve
good and reliable joints each time.
3) Develop a database on the parameters
for the brazing process to ensure
quality and reproducibility.
4) define the allowable related to a
given joint geometry and brazing process
in order to define the potential of such
joining techniques for structural
aerospace applications.
