with coating layr of multi-phase

宫城工业大学实验室提出了一种新的粉末冶金制备功能梯度材料的方法，利用粉末工艺过滤效应和金属/金属复合效应相结合的方法，制备出了在整个横截面上没有明显裂纹的SUS 316L/3 Y-PSZ功能梯度材料。使用平均粒径为5 μ m的雾化SUS 316L粉末和平均粒径为0.3 μ m的3 Y-PSZ粉末作为原料粉末。对金属和陶瓷各自的粉末床（10级分层）以及不同涂层厚度的复合颗粒进行了各种频率的振动。然后在高纯Ar气中热压烧结，在烧结温度冷却过程中以及在热负荷试验和热冲击试验中，均未发现类似裂纹的不连续性。

A Novel powder metullugical fabrication of a Functionaly Gradient Material was proposed by our laboratory of miyagi national college of technology.The Functionaly Gradient Materials of SUS316L/3Y-PSZ without a visible clack-like discontinuity throughout an overall cross-section were produced by a combining process with a powder technological filter effect and a compound effect of metal/ceramics composite particles.Atomized SUS316L powder of mean particle diameter in 5mum and 3Y-PSZ of mean particle diameter in 0.3mum were used raw material powders. Vibrations of various frequency were made an addition to respective powder beds (a 10 steps stratum) of metal and ceramics and the composite particles of different coating thickness. After that the powder beds were sintered by hot press in high purity Ar gas.The crack-like discontinuity during cooling from sintering temperature and in a thermal loading tests and a thermal shock test could not been discernible in the sintered compacts of the Functionaly Gradient Material.
