APPARATUS AND METHOD FOR DIRECT WRITING OF SINGLE CRYSTAL SUPER ALLOYS AND METALS |
摘要 |
Methods for direct writing of single crystal super alloys and metals are provided. The method can include: heating a substrate (23) positioned on a base plate (22) to a predetermined temperature using a first heater (24); using a laser (26) to form a melt pool (34) on a surface of the substrate (23); introducing a superalloy powder (32) to the melt pool (34); measuring the temperature of the melt pool (34); receiving the temperature measured at a controller (40); and using an auxiliary heat source (41) in communication with the controller (40) to adjust the temperature of the melt pool (34). The predetermined temperature is below the substrate's melting point. The laser (26) and the base plate (22) are movable relative to each other, with the laser (26) being used for direct metal deposition. An apparatus (20) is also generally provided for direct writing of single crystal super alloys and metals. |
