Laser cladding as a repair technique for BLISKs out of titanium and nickel base alloys used in aero engines

Abstract

The most commonly used materials in aero engines are Nickel and Titanium base alloys. Exemplary for these types of alloys the macro and micro structure and the static and dynamic mechanical properties of the laser cladded Nickel base Superalloy Inconel 718 and the laser cladded Titanium base alloys Ti-17, Ti-6Al-4V and Ti-6246 are described and discussed in a first step. Based on the results achieved within step 1 the process layout is transferred and adapted onto real components in a second step. Tip and leading edge repairs of real components are demonstrated.The most commonly used materials in aero engines are Nickel and Titanium base alloys.
