Abstract：In order to study the friction performance and the micro dynamics of ultra-high molecular weight polyethylene(UHMWPE)pipe in the salt water transport process, we applied the CFT-I material surface performance comprehensive test instrument to the rotating friction on UHMWPE material specimen under three different conditions of dry friction, water lubrication and salt water lubrication. Then we analyzed the regularity of the influence on the properties of UHMWPE friction and wear particles in the process of the salt water lubrication and the microscopic movement form by the scanning electron microscope and surface contourgraph under variable factors such as the speed of 500 r/min, load of 50 N, lasting for 25 min; the speed of 500 r/min, lasting for 10 min and the load of 30 N, 50 N, 70 N, 90 N and 110 N; load of 50 N, lasting for 10 min, and the speed of 300 r/min, 500 r/min, 700 r/min, 900 r/min and 1100 r/min. Results showed that UHMWPE wear mechanisms are mainly abrasive wear under the salt water lubrication, the friction coefficient and wear quantity in salty lubrication are minimal compared with those under the dry friction and water lubrication, and the friction coefficient increased first and then decreased with the increase of load and speed, presenting downtrend with the time extension. Salt water lubricant in the friction process can form strong antifriction performance of lubricant film as well as salt water crystallization particles which play the ball role, which can reduce the UHMWPE wear in salt water delivery, this paper made a theoretical basis for the application of UHMWPE in salt water environment.
