Assembly and embedding of nanoparticles in a Ni-matrix

Abstract: To create a new kind of surface suitable for tribological applications, a monolayer of nanoparticles was deposited on a metal-coated substrate. This was followed by embedding the nanoparticles in a metal matrix. For the deposition, SiO₂ nanoparticles were used, succeeded by an embedding by Ni electroplating. For the deposition, the SiO₂ nanoparticles were attached to the surface using a linker of CO₂H and SH. In this experiment, the linker connects the nanoparticles with an Au surface. To obtain an optimal linkage between the surface and nanoparticles, various deposition technologies like dip-coating, spin-coating, and electrophoresis were investigated. Afterwards, the SiO₂ nanoparticles were embedded by electroplating. The results have shown that it is possible to create a surface with a defined roughness. Furthermore, the mechanical investigations indicate that the nanoparticles have an influence on the hardness of the developed layer.
