In order to select a good matching material with Polyetheretherketone(PEEK) to adapt to the 〖JP2〗severe dry friction conditions,a pindisk friction tester was used to study on the friction and wear properties of PEEK matching with Si3N4 ceramic,2507 stainless steel and 6061 aluminum.The results show that the friction coefficient and wear rate of the three pairs are increased with the increasing of sliding speed.When the PEEK is matched with ceramic materials,the friction coefficient is the largest and the ploughing effect of PEEK surface is significant,and the wear mechanism is mainly abrasive wear and adhesive wear.When PEEK is matched with 2507 stainless steel and 6061 aluminum alloy,the ploughing effect is weakened,material transfer occurs at the friction interface and an adhesion layer is formed.The friction surface is smooth and the friction coefficient is low.Under dry friction condition,PEEK and 6061 aluminum alloy pair show better tribological properties at low speed,and PEEK and 2057 stainless steel pair has better tribological properties at high speed.
