Three kinds of metal-plastic multilayer composites, which were composed of a steel backing, a middle layer of sintered porous bronze and a surface layer of polytetrafluoroethylene (PTFE) filled by Pb or Cu 2 O powders, were prepared. The friction and wear properties as well as the limiting pressure times velocity (PV) values of these metal-plastic multilayer composites sliding against 45 carbon...
Four kinds of polytetrafluoroethylene (PTFE)-based composite, pure PTFE, PTFE + 30vol.%Cu, PTFE +30vol.%Pb and PTFE + 30vol.%Ni composite, were prepared. The friction and wear properties of these metal powder filled PTFE composites sliding against GCr15 bearing steel under both dry and lubricated conditions were studied using an MHK-500 ring-block wear tester. The worn surfaces of the PTFE composites...
A kind of polytetrafluoroethylene (PTFE) based multilayer self-lubricating composite material, made of a steel backing, a sintered porous bronze middle layer and a surface layer consisting of a mixture of PTFE and Pb powders, was prepared. The friction and wear properties as well as the limiting PV (pressure times velocity) values of the PTFE composite sliding against stainless steel with lubrication...
A material composed of a steel backing, a sintered porous bronze middle layer and a layer of reinforced PTFE, which is named JS material, was prepared. The friction, wear and limiting PV values of this material under dry friction as well as the lubrication of number 20 mechanical oil were studied using a MPV-1500 friction tester. The worn surface of JS material and the transfer film formed on the...
