Mechanical and tribological laboratory (CDAL)
The objective of the mechanical and tribological laboratory is to determine the effect of microstructure on the properties of materials. Determine the mechanical properties and resistance to wear of materials and components and the improvement of these properties with thermal treatments.
The mechanical testing equipment allows the mechanical characterization of materials and components through different types of tests: hardness, traction...
Tribological characterization allows the frictional behavior of systems in relative motion to be known. Roughness, friction and wear tests are carried out.
Services it offers

Tribological characterization of materials (friction and wear).
Microstructural characterization of materials.
FUSED3D project
Challenge: This project is one of the 4 sub-projects of the project of the BASE 3D project, which aims to improve the systems of shaping parts by deposition of hot material in semi-molten or pasty form, basically applicable to plastic materials, metallic and ceramic that can be presented alone or hybridized to acquire new functionalities or make their processing viable through more efficient and sustainable methods, while benefiting from the advantages provided by additive manufacturing and opening new areas of uses and hitherto unexplored applications.
Solution: A viscosity control system has been obtained in second-melt aluminum alloys (AlSi9Cu3 alloy) that allows obtaining suitable microstructures to be used in a 3D printer with controlled melting.
Development project for new additive manufacturing processes for the production of metal parts
Challenge: The main objective of this project is the development of new metal additive manufacturing processes, based on fused deposition modeling (FDM) techniques, through an adequate design of the raw materials, with the aim of reducing drastically the price of metal components manufactured by additive manufacturing and facilitate their implementation in the aeronautical sector.
Solution: Aluminum alloys have been obtained from first-melt aluminum alloys (A357 alloys) with a microstructure capable of being semi-cast in an additive manufacturing process.
