Sintered Preforms Hasten Aeroengine Braze Repairs
01 Mar 2005
Use of pre-sintered preforms as a high quality repair process can now extend the life of engine components by approximately 300%, significantly reducing costs associated with replacement parts and labour. Morgan Advanced Ceramics is offering an approved OEM and designated engine repair process for aeroengine component repairs that is a faster and more reliable method than traditional welding or brazing paste.
With turbine temperatures reaching up to 1300ºC and the presence of hot corrosive gases, components experience considerable erosion and wear. Pre-sintered preforms consist of a blend of superalloy and low melting point braze alloy. They are compatible with the base material, which is customised to fit the shape of the component, tack welded into place and then brazed.
