Reconstructive Repair of Hardware and Tooling
Keystone has developed multiple specialized component repair methods for critical aerospace hardware. The reconstruction repair of damaged blades on integrally bladed rotors (IBRs) is possible with the combined innovation of high-quality metal deposition and the dynamic conversion of cast microstructures into fine grain structure for wrought-like mechanical properties. Weld rejuvenation using solid-state microstructure conversion has proven to be an effective repair method for highly stresses components.
Leading edge and tip reconstruction of industrial gas turbine blades is possible in hard-to-weld alloys using Keystone metal deposition methods.
The dimensional reconstruction and repair of specialized steel tooling for composite lay-up is a prime application of metal deposition methods developed by Keystone.
