Effects of PEEK's surface roughness on seizure behaviors of PEEK/steel pairs under oil-lubricated sliding contacts

Effects of PEEK's surface roughness on seizure behaviors of PEEK/steel pairs under oil-lubricated sliding contacts

Effects of surface roughness of polyether ether ketone (PEEK) on the seizure behaviors of PEEK/steel pairs are studied using a block-on-ring wear tester under oil-lubricated conditions. The blocks are made of unfilled PEEK and a PEEK composite filled with carbon fibers of 30 mass%. The block&apo...
