摘要
In the present invention, (a) (i) a powder made of aluminum or aluminum alloy and a metal powder including magnesium powder and (ii) a mixed powder including a polymer or ceramic powder are prepared, but the content of the polymer or ceramic powder in the mixed powder Preparing two or more different kinds of mixed powders; (b) stacking two or more kinds of mixed powders prepared in step (a) to form a gradient functional laminate having different polymer or ceramic powder content fractions relative to the metal powder content of each layer as it goes from the lowermost layer to the uppermost layer. step; And (c) preparing a gradient functional composite material by performing atmospheric pressure sintering or discharge plasma sintering of the gradient functional laminate.
