MATERIAL FOR USE IN COMPOSITE SLIDING SURFACE BEARINGS AND PROCESS OF MANUFACTURING THE MATERIAL

摘要

A bearing material having a plastic lubricating layer consists of a metallic supporting layer and a lubricating layer bound to the latter and consisting of fluorine-containing polymer which forms a matrix and in which a metal powder with a high affinity for fluorine is finely dispersed. To increase the service life, a fluorine-containing polymer is used whose X-ray diffraction pattern produced with CuK alpha radiation contains a sharp intensity maximum with a double Bragg angle of 2 theta = 18.07 +/- 0.03 DEG and which has a melting range of 320 to 350 DEG C and contains the metal fluoride and metal oxyfluoride. ……
