Claims23
A slide member comprising a surface layer of a Pb alloy on a slide surface for a mating member, wherein said Pb alloy comprises at least 3% and at most 20% by weight Sn, and said Pb alloy has a crystal form with an orientation index in a (h00) plane by Miller indices being set in a range of 80 to 100%.
A slide member comprising a surface layer of a Pb alloy on a slide surface for a mating member, wherein said Pb alloy comprises at least 3% and at most 20% by weight Sn, said Pb alloy has a crystal form with an orientation index in a (h00) plane by Miller indices being set in a range of 80 to 100%, and the crystals of said Pb alloy are formed into pyramids with the apex of each pyramid being directed to the mating member and each pyramid having a base length d of 8 .mu.m or less.
A slide member comprising a surface layer of a Pb alloy on a slide surface for a mating member, wherein the Pb alloy consists essentially of 80 to 90% by weight of Pb, 3 to 20% by weight of Sn, and 0 to 10% by weight of at least one element selected from the group consisting of Cu, In and Ag, and the Pb alloy has a crystal form with an orientation index in a (h00) plane by Miller indices in the range of 80 to 100%.
A slide member comprising a surface layer of a Pb alloy on a slide surface for a mating member, wherein the Pb alloy consists essentially of 80 to 90% by weight of Pb, 3 to 20% by weight of Sn, and 0 to 10% by weight of at least one element selected from the group consisting of Cu, In and Ag, and the Pb alloy has a crystal form with an orientation index in a (h00) plane by Miller indices in the range of 80 to 100%, and the crystals of the Pb alloy are formed into pyramids with the apex of each pyramid being directed to the mating member and each pyramid having a base length d of 8 .mu.m or less.
A slide bearing comprising:
- an inner backing made of a rolled steel plate;
- a medium lining made of copper, copper-based alloy, aluminum or aluminum-based alloy and being 50 to 500 .mu.m thick, and
- an outer surface layer being 5 to 50 .mu.thick and being made of a Pb alloy on a slide surface of the lining layer,
- wherein the Pb alloy consists essentially of 3 to 20% by weight of Sn, 80 to 90% weight of Pb and at least one element selected from the group consisting of Cu, In and Ag in a total amount of 0 to 10% by weight, and
- the Pb alloy has a crystal form with an orientation index in a (h00) plane by Miller indices in the range of 80 to 100%.
