摘要： An aluminum-based material for anti-friction bearings composed of an aluminum alloy with 10-25 wt % tin or 5-25 wt % lead, impurity-caused components characterized by 0.75-2.5 wt % iron and an alloy additive capable of forming an intermetallic compound having a spherical phase homogeneously distributed in the aluminum alloy. The alloy additive is one of: a) manganese and silicon, in which the weight percentage fractions of manganese and silicon are at least half the weight percentage fraction of the iron and for manganese, at most 3 wt %, and for silicon, at most 2 wt %; b) 0.1-0.5 wt % cobalt; and c) 0.1-0.5 wt % molybdenum.

摘要： A material for composite sliding surface bearings having a plastic sliding layer comprises a metallic backing layer and a sliding layer that is joined to the backing layer and consists of a matrix-forming fluorine-containing polymer, in which a metal powder having a high affinity to fluorine is finely dispersed. In order to reduce the friction torque and the wear rate, the fluorine-containing polymer contains metal fluoride and metal oxyfluoride and consists of monoclinally crystallized PVDF, amorphous PVDF and a novel polymer, which in an X-ray diffractogram prepared by CuK .alpha.-radiation has a sharp intensity peak at a double Bragg angle of 2.theta.=18.07.+-.0.03.degree. and has a melting range of 320.degree. to 350.degree.
