Abstract
In the third project, an 1-methyl-2-pyrrolidinone (NMP) solution of ATSP oligomer was cast on a metal surface. Tribological tests showed that when ZonylRTM was present as a third body during sliding, the ATSP system had low friction and much lower wear compared to a commercial PTFE based coating. TOF-SIMS analysis showed that ZonylRTM particles had migrated down into the coating at least 1.5 microm deep when the wear track was only 0.2 microm deep, which means that a ATSP and Zonyl RTM composite had formed due to pressure and sliding. It is believe that ATSP with ZonylRTM coating system has very promising prospects for use as a soft protective coating for tribological applications.
