Additive manufacturing is an emerging manufacturing and remanufacturing (repair) technique for value-added materials such as INCONELTM718 (IN718), particularly using a laser beam as the thermal source. In this study, a continuous wave fiber laser was used to deposit IN718 powders on IN718 substrates in the solution heat treated or fully heat treated conditions.
Direct diode laser deposition of functionally graded ti In this work, three dimensional functionally graded structures of Ti-6Al-4V and Inconel 718 are fabricated by laser direct metal deposition (LDMD) on Inconel 718 substrate. The multi-track parts are built at a range of powder mass flow rates using a side nozzle and 1.5 kW Diode laser operating in both continuous and pulsed beam modes.
Laser direct metal deposition (LDMD) has developed from a prototyping to a single metal manufacturing tool. Its potential for creating multimaterial and functionally graded structures is now beginning to be explored. This work is a first part of a study in which a single layer of Inconel 718
