Sliding tests on the patterns were conducted against a 2-mm diameter Si 3N 4 ball at varying normal loads and sliding velocities. It was observed that the pitch of the SU-8 pattern on Si substrate had a significant effect on the initial coefficient of friction and wear durability. Initial coefficient of friction studies have concluded that the SU-8 polymeric micro-dots improved the tribological properties by sharing the normal force and reducing the contact area. For the wear durability test, ultra-thin layer of perfluoropolyether was over-coated onto SU-8 micro-dot specimens, and the optimized pitch specimens have shown wear durability of more than 100,000 cycles at a normal load of 350 mN. © 2011 Springer Science+Business Media, LLC.||Source Title:||Tribology Letters||URI:||http://scholarbank.nus.edu.sg/handle/10635/85558||ISSN:||10238883||DOI:||10.1007/s11249-011-9765-y|
