An investigation of tribological properties, friction, and wear rate was conducted for various blends of polyacetal (POM)/polytetrafluorpethylene (PTFE), polyamide66 (PA66)/PTFE, high molecular weight polyethylene (HMWPE), and HMWPE/polyamide12 (PA12). The results were summarized as follows : 1) The frictional coefficients of POM/PTFE, PA66/PTFE, and HMWPE/PTFE blends were smaller than those of POM/graphite (Gra), POM/molybdenum disulfide (MoS2), PA66/Gra, and PA66/MoS2 composites. The frictional coefficients of these blends tested against the stainless steel (SU S304) disk were larger than when tested against the zine plated disk. 2) The dependence of the frictional coefficient of HMWPE/PA12 blends approached that of neat HMWPE with increasing HMWPE content. 3) The wear rates of POM/PTFE, PA66/PTFE, and HMWPE/PTFE blends were smaller than those of POM/ Gra, POM/MoS2, PA66/Gra, and PA66/MoS2 composites. The wear rates of these blends tested against the stainles steel (SUS304) disk were smaller than when tested against the zine plated disk.
