Abstract: The present disclosure relates to aerosol delivery devices, methods of producing such devices, and elements of such devices. In some embodiments, the present disclosure provides devices configured for vaporization of an aerosol precursor composition that is contained in a reservoir and transported to a heating element by a liquid transport element. The liquid transport element may include a porous monolith.

Abstract: A bearing having improved wear resistance has a bearing material of a copper-tin-bismuth alloy which may also include phosphorus which has excellent strength, due to the solid solution of copper, tin and phosphorus (when used), attached to a steel backing shell. The material also has good lubricity as a result of the presence of the bismuth which also promotes tin mobilization and formation of a layer of tin on the bearing surface upon use of the bearing. The addition of small amounts of relatively small hard particles in the copper-tin-matrix, particularly Fe3P, MoSi2 or a mixture thereof, provides a suitable hard surface artifact to improve the wear resistance of the bearing material. The bearing includes a sintered powder compact bearing material of a copper-tin-bismuth alloy powder and a metal compound powder which is bonded to a steel backing shell, wherein the metal compound powder has an average particle size of less than 10 ?m.

Abstract: A lead-free bearing includes a bronze matrix powder metal bearing layer bonded to a steel backing a fully densified. The bearing material has about 8 to 12% by weight tin, about 1 to less than 5% by weight bismuth, and about 0.03 to 0.08% by weight phosphorus, with the balance being copper. The tin is soluable in the copper to yield the bronze matrix, and the bismuth exists as finely dispersed, undissolved islands through the matrix. Such bearings exhibit physical properties comparable to or better than those of traditional bronze-lead bearings and improved wear in seizure properties.
