Fabrication of large components by Spark Plasma Sintering (SPS)

SPS is an innovative sintering process that is emerging as a key enabling technology in the processing of numerous advanced materials however up to now the industrial upscale of the technology was limited due to the reduced size of the samples attainable and the material heterogeneities in large samples. The Nanomaterials and Nanotechnology Research Center (CINN) has both the experience and a unique pre-industrial equipment to perform R&D and small series production of components up to 400 mm in diameter of nanostructured materials, composite materials and gradient materials with tailored microstructures.

New and innovative aspects
CINN's equipment is nowadays world's largest SPS facility (12 meters high, 6 meters wide and 5 meters deep) and incorporates an additional induction heating process to reduce thermal gradients thus allowing to obtain homogeneous materials in an industrialized process.

Main advantages of its use
The main advantages of Spark Plasma Sintering (SPS) over conventional hot pressing and sintering are:

Use of lower temperature and mould pressure
Reduction of cycle times to just a few minutes
No need for sintering additives
Fabrication of fully dense sintered components retaining nano- and ultrafine microstructures
Sintering of composites with components that react with each other (metastable microstructures)
Diffusion bonding of dissimilar materials
Additionally CINN's SPS is a customized unit equipped with a radial, inductive heating system to prevent radial temperature gradients in large-sized components or to facilitate the inductive heating of materials that are otherwise inadequately conductive at room temperature. This taylor-made system is particularly suitable for industrial demonstration activities allowing the production of prototypes with dimensions up to 400 mm diameter.

About the vendor organization

Nanomaterials and Nanotechnology Research Center (CINN)Nanomaterials and Nanotechnology Research Center (CINN)
The CINN is a joint research center created in 2007 as an institutional joint initiative between the Spanish Council for Scientific Research (CSIC), the Government of Asturias and the University of Oviedo.

CINNs' research is focused on the creation, characterization and understanding of the behavior of new multifunctional materials on the nano, micro and macro scale, overcoming thereby the performance constraints that limit present-day materials and processes.
Since 2005 the research group on "Synthesis and Advanced Characterizaction of Nanocomposites and Bio-inspired Materials" works intensively on the development of innovative multifunctional materials by SPS and holds 12 patents related to this technology.
