摘要

Layered Manufacturing (LM) is emerging as a new technology in recent years that enables the fabrication of three-dimensional heterogeneous objects, especially Functionally Graded Materials (FGM) whose composition or the microstructure is locally varied to alter the material properties. This paper presents a new fabrication method for fabricating FGM component by using electromagnetic compressed Plasma Deposition Manufacturing (PDM) process. Ni-base alloy/Al_2O_3-ceramic FGM test component with continuous gradient transition composition were fabricated in the PDM process and the specimens' cross-sections were analyzed using optical metallography and Micro-hardness test. No defects were noticed on the cross-sections and the micro-hardness of the FGM component was increasing gradually while Al_2O_3-ceramic ingredient ratio increased. With the quantity of Al_2O_3-ceramic granule joined in the molten bath increasing, the Ni-base alloy's organization proportion reduced significantly according predefined materials gradients.
