Nanomaterials Processed by Spark Plasma Sintering [PDF]

Journal of Nanomaterials, 2013
The spark plasma sintering (SPS), a variant of field-assisted sintering (FAST) or pulsed electric current sintering (PECS), is a novel pressure assisted pulsed electric current sintering process, which utilizes ON-OFF DC pulse energizing. Due to the repeated application of an ON-OFF DC pulse voltage and current flow between powder particles, the spark ...

Spark Plasma Sintering of NiCrSiBC Alloys

, 2023
Nickel-based alloys of the NiCrSiBC system (colmonoy alloys) are normally deposited on stainless-steel substrates for coating applications, once they present high resistance to wear and corrosion at high temperatures. Typically, deposition occurs through welding processes, such as PTA (plasma transferred arc) or laser cladding.
