Abstract

The layerwise laser cladding of powdered alloy based on intermetallic gamma Ni3Al phase is studied. The effect deposition parameters have on the geometry of the deposited beads is shown. Microstructures are investigated and the cracking susceptibility of the deposited material is analyzed. The effective deposition parameters are determined within a range of specific laser energy inputs of (2–8) × 106 J kg−1 at beam scanning rates of (1.67–10) × 10−3 m/s and a powder feed of 6.3 × 10−5 kg/s−1.
