Sialon ceramics have good toughness, high hardness, wear resistance, and high-temperature oxidation resistance.
Which has a greater impact on the sintering mechanism: the SPS pulse current or the pressure? Please click here for detailed analysis.
There are several kinds of molds used in the SPS process, like graphite molds, cemented carbide molds, ceramic molds used in the SPS process.
Spark plasma sintering (SPS) is a technology that uses DC pulses to heat the sample and combines axial pressure to assist densification.
Spark Plasma Sintering has some advantages, such as short sintering time, fast heating rate, high sintering pressure, etc.
In order to better understand the mechanism of spark plasma sintering, it is essential to explore the current distribution in the sample and graphite mode.
There is no consensus on whether the rapid densification factor in spark plasma sintering is derived from the discharge spark plasma generated by high-energy DC pulses.
