Details

Tittle:
R-Y-D for large components by Spark Plasma Sintering (SPS)
Summary:
A Spanish research centre in nanomaterials and nanotechnology has both the experience and a unique preindustrial equipment to perform R-Y-D and small series production of components up to 400 mm in size of nanostructured materials, composite materials and gradient materials with tailored microstructures using Spark Plasma Sintering (SPS). Partners interested in the development of high value products based on this technology through joint R+D projects or technical cooperation agreements are sought.
Description:
A Spanish research centre working in nanomaterials and nanotechnology has the world´s largest SPS (Spark Plasma Sintering) facility nowadays.
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 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 the research centre´s SPS facility 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 tailor-made system is particularly suitable for industrial demonstration activities allowing the production of prototypes with dimensions up to 400 mm diameter. The main specifications of the equipment are shown below:
· 400 tons pressing force
· Maximum capacity of 1200 kW
· Voltage: 1-20 V
· Current: 40 kA
· Maximum Temperature: 2200ºC
· Maximum piece dimensions: 400 mm
The research centre seeks companies and research institutions interested in the development of high-value products based on the SPS technology through joint R+D projects or technical cooperation agreements. Some of the fields of interests are:
· Ceramic armours
· Transparent ceramic windows
· Thermoelectric materials
· Ultra-hard cutting tools
· Wear-resistant composite materials
· Nanostructured materials
· Hard metals
· High-performance aluminium alloys
· Magnetic materials
Advantages and Innovations:
The Spanish research centre´s equipment is nowadays the 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 even with sizes as large as 400mm.
