Hot Presses and Spark Plasma Sinter Technology

Components made for very harsh environments require very special processes to make them. With sintering equipment such as “Hot Presses” or “Spark Plasma Sintering Machines” components with high-end material properties required to meet demanding applications can become manufacture.

Typical material systems for Spark Plasma Sinter Technology:

Metals: W, Mo, Cr, Ru, Si, Cu, Cu (+W / Cr)
Intermetallics: TiAl, Ni3Al, PbTe, SmCo5
Carbides: WC, B4C, SiC, TiC, ZrC
Nitrides: AlN, TiN, Si3N4 (+TiN), hBN (+TiB2)
MMC / CMC: Al / Ti (+ SiC / Al2O3), Steel (+ TiC/N), Co / Cr / Pt (+ Oxides)
Cutting Tools: WC-Co/Ni/Steel (+cBN, +Diam.), Al2O3-Ti(C,N)
Armor materials: B4C, SiC, ZrB2, TiB2, Al2O3 (+CNT)
Transparent: Spinel, Al2O3,
Nano-structured Materials
Functional / Functionally Graded Materials („FGM“)
