This paper investigates and analyses use of numerical modeling by finite element method (FEM) at studying of consolidation processes of materials from powder by spark plasma sintering (SPS). Tasks of SPS process optimization is discussed in detail. Examples of numeric analysis of SPS of current conducting and non-conducting materials are given.
Spark Plasma Sintering (SPS), as it is commonly referred to, is a rapid sintering process, where the sintering cycle can be completed in minutes. This opens up the possibility of making ceramics with new microstructures and properties. SPS has some similarities to hot-pressing, which involves the application of pressure during sintering.
pulse DC voltage is on, spark discharge/plasma generates between adjacent particles [19,20], and individual ones are spontaneously heated, leading to the activation, purification of par‐ ticle exterior surface and removing of oxide film, helping the rapid material diffusion and 206 Sintering Applications
