Fast Processing of Advanced Ceramics and Metals into Near Net-Shape Parts
To enable quick fabrication of high-temperature advanced ceramics and metals, Quad City Manufacturing Lab (QCML) offers spark plasma sintering for near net-shape processing of parts.
Spark Plasma Sintering (SPS) is the process of consolidating metal and ceramic powders using high temperatures and pressures. SPS utilizes uniaxial loading and pulsed DC currents to produce near net-shape components. Offering far faster processing times than traditional methods, spark plasma sintering leads to better mechanical properties, reducing grain growth in samples and sometimes even preserving the existing Nano-features within a specimen after processing, all with greater control over material properties.
QCML Spark Plasma Sintering Capabilities
QCML’s facility has one 10-ton and one 25-ton Spark Plasma Sintering system that can generate temperatures up to 2200°C. Graphite tooling is typically used to create dies, which are then used to contain the powders and form the components. Temperatures are measured with thermocouples or pyrometers, and processing is conducted in argon, nitrogen, vacuum, or helium atmospheres.
QCML offers spark plasma sintering capabilities for a wide range of applications and industries, including:
- General manufacturing
Our facility allows for a wide variety of materials to be consolidated, including silicon nitride, silicon carbide, boron carbide, tungsten, carbides, nitrides, MgAlB14 (BAM), titanium alloys, and magnesium alloys. With hold times typically between 5-10 minutes, Spark Plasma Sintering from QCML is a reliable way to rapidly consolidate high-temperature materials, regardless of industry, while realizing improved mechanical properties.
