为了了解放电等离子烧结(SPS)的机理，进行了典型的烧结实验。根据直观观察和特征微观结构分析的结果，我们认为在SPS过程中确实发生了火花放电。由于放电效应，微隙中会产生高温火花等离子体。在SPS过程中，在火花放电、焦耳加热、电扩散和塑性变形效应的共同作用下，可以实现快速高效的烧结。(C)2014 Acta Materialia Inc.由Elsevier Ltd.出版。保留所有权利。
Typical sintering experiments were conducted to understand the spark plasma sintering (SPS) mechanisms. Based on the results of the direct visual observations and characteristic microstructure analysis, we believe that spark discharge does indeed occur during the SPS process. The high-temperature spark plasma could be generated in the microgaps due to the discharge effect. Fast and efficient sintering can be achieved under the combined action of spark discharge, Joule heating, electrical diffusion and plastic deformation effect in the SPS process.
