The fabrication of disk shaped functionally gradient material with an optimum distribution of composition for thermal stress reduction in a specific material combination of PSZ/Stainless Steel is described. The thermal stress generated during cooling from sintering temperature was analyzed by finite element method as a function of compositional distribution and sample size.According to the optimum compositional gradient, the sintered compact of the PSZ/SUS304 functionally gradient material was successfully fabricated.

本文介绍了在PSZ/不锈钢的特定材料组合中制备具有最佳成分分布的盘形梯度功能材料以降低热应力。采用有限元方法分析了烧结温度冷却过程中产生的热应力随成分分布和试样尺寸的变化规律，并根据最佳成分梯度成功制备了PSZ/SUS 304梯度功能材料烧结坯。
