FAST (Field-assisted Sintering Technology)/ DCS (Direct Current Sintering) is an advanced powder metallurgy technology that integrates plasma activation, pressurization, heating and sintering of alloy powders. Under the combined action of current and pressure, materials can be synthesized in only one step. With its rapid heating and cooling rates, high sintering efficiency and good connection effect, it has attracted widespread attention and heated discussions among researchers. With the continuous deepening of research, this technology has been widely used in the preparation of various materials, such as metals, ceramics, and composite materials. Including materials that are not easy to sinter, novel carbon-containing materials, most nanocrystalline metal functional gradient materials and materials with complex shapes.
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.
Fast Hot Pressing Sintering ceramic and metal composite to obtain a metal-ceramic composite material that is both strong and wear-resistant.
Using of SPS Spark Plasma Sintering Technology is a new concept for cross-scale, multi-level design of tungsten-copper composites.
SPS Spark Plasma Sintering Furnace records the densification process in real-time of ZrO2–SiO2 Composite Glass Ceramic Materials
Spark Plasma Sintering is an efficient experimental method for Boron Carbide Bulletproof Ceramics. It obtains the samples in a maximum of two hours.
Direct current sintering (DCS) was used to study the various properties of barium titanate-based HEA with different formulations.
Spark plasma sintering technology has a fast heating rate and short holding time, so the product has a small grain size and few pores, and can achieve an unprecedented bending strength of 94.5MPa.
