Presintered performs speed aeroengine repairs
The Wesgo Metals Division of Morgan Advanced Ceramics is offering aeroengine manufacturers presintered preforms for high-temperature braze repair applications.
Unlike traditional brazing pastes and green tapes, porosity in PSPs is less than 2%, which helps eliminate shrinkage.
PSPs are easy to handle and environmentally safe, providing a cost-effective braze repair solution.
Brazed parts require minimal grinding to restore components to original dimensions.
To further decrease milling on graded geometries, MAC's PSPs can be manufactured in tapered preforms.
Additionally, brazing allows whole components to be heated in a vacuum furnace, reducing distortions and providing increased consistency, resulting in a high-quality repair process.
For customised applications, MAC offers PSPs in various shapes, including curved, tapered and cylindrical with thickness ranging from 0.3 to 5mm.
Unlike flat preforms, for reduced processing time, curved PSPs eliminate the need for a second braze cycle on both convex and concave surfaces.
For dimensionally restoring holes and bores, cylindrical preforms are ideal because they will not sag or over flow during brazing.
