电泳沉积(EPD)是由合适的稳定悬浮液制备板状二元功能梯度材料(FGM)的一种有吸引力的成形工艺。本文介绍了以丁酮、正丁胺和硝酸纤维素溶液为基础的非水稳定悬浮液通过电火花放电制备Al_2O_3和ZrO_2功能梯度块体材料的能力。介绍了EPD工艺参数和烧结工艺，并用压痕法在样品横截面上测量了复合材料的密度、硬度、韧性和残余应力。扫描电子显微镜证实烧结体为功能梯度材料。
Electrophoretic deposition (EPD) is an attractive forming process to fabricate plate shaped binary functionally graded materials (FGMs) from suitable stable suspensions. In the present work, the capability to produce Al2O3 and ZrO2 functionally graded bulk material by means of EPD from a non‐aqueous stable suspension based on 2‐butanone, n‐butylamine and cellulose nitrate solution is presented. The EPD processing parameters and sintering are described, and the density of the FGM composite, hardness, toughness and residual stresses are measured using indentation methods on cross‐sections of the sample. Scanning electron microscopy confirmed that the sintered body is an FGM.
