Study on Preparation of Nano-Al_2O_3/Ni-based Superalloy Composite Powder and Laser 3D Printing AITranslate
Abstract AITranslate
Using polyethylene glycol as dispersants and adhesives,nano-sized Al2O3 ceramic particles were assembled to the surface of Ni-based superalloy spherical particle to prepare Al2O3/Ni-based superalloy powder by the two steps method of ultrasonic dispersion and high speed stirring.Molding Al2O3/Ni-based superalloy composites were prepared by the laser 3 D printing.The results show that the composite powder used for laser 3 D printing technology can be successfully prepared by two steps process of ultrasonic dispersion and high speed stirring.After laser 3 D printing,the microstructure of molding materials is mainly represented by the columnar crystal and isometric crystal structure,uniform and compact,the nano-Al2O3 granules are uniformly distributed in the matrix.The microhardness(HV)of the composites can reach to 405.81.
