Abstract (en)
[origin: WO2014120991A1] An additive manufacturing process (110) wherein a powder (116) including a superalloy material and flux is selectively melted in layers with a laser beam (124) to form a superalloy component (126). The flux performs a cleaning function to react with contaminants to float them to the surface of the melt to form a slag. The flux also provides a shielding function, thereby eliminating the need for an inert cover gas. The powder may be a mixture of alloy and flux particles, or it may be formed of composite alloy/flux particles.
