Stellite 6
Alloy: Co / Cr / W / C
Wire feedstock: WT-6 GMAW-C
Summary
Stellite 6 is a cobalt base superally consisting of a matrix containing dispersed carbides. It is a wear resistance alloy, with excellent corrosion and mechanical properties up to 500 degrees Celsius. Because of its properties it used in valves seals and gates, pump shafts and bearings, erosion shields and rolling couples. Furthermore Stellite 6 is used in aero engines, gas turbines and the nuclear industry.
Highlights

General explanation
Printing strategies
Straight lines strategy: several welding beads overlapped next to each other
Oscillation: continuous zig-zag bead that fills the entire layer
Heat treatement
Stress relief: due to the high residual stresses build up in the WAAM product, this heat treatment is necessary to minize residual stresses.
