Abstract The lubricity of coatings made from different types carbon nanoparticles such as onions, nanohorns and nanotubes is investigated on line-patterned AISI 304 stainless-steel substrates using ball-on-disc tribometry over 200,000 sliding cycles. Picosecond direct laser interference patterning used to create line-patterns the substrate surfaces which are subsequently coated by electrophoret...
