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.
