New production processes due to nanoparticles and nanolayers (NanoWearResist)
Duration: March 2009 - February 2012
The project concentrates on fabrication of wear resistant lightweight construction materials and of components with local wear resistance. The production of the entire value chain, namely, from specially modified nanoparticles to their integration into finished components will be established. The results are of particular importance for light weight, energy and environmental technologies.
Nanoparticles are coated and functionalized in order
- to achieve good dispersibility in metal melts,
- to ensure good bonding between the nanoparticles and metal matrices,
- to protect them physically and chemically in molten metal bath
- to develop new joining/welding methods which will be tested on various different components.
A simple plating procedure based on competitive reactants and solvents was developed for the functionalization of the particles enabling the coating with metallic layers on different surfaces.
