Claims
- 1. A slide member comprising a surface layer of a Pb alloy on a slide surface for a mating member, wherein said Pb alloy has a crystal form with an orientation index in a (h00) plane by Miller indices being set in a range 60 to 100%.
- 2. A slide member according to claim 1, wherein said orientation index is greater than or equal to 97%.
- 3. A slide member according to claim 2, wherein said Pb alloy contains 3% (inclusive) to 20% (inclusive) by weight of Sn.
- 4. A slide member according to claim 3 wherein said Pb alloy contains at most 10% by weight of at least one element selected from the group consisting of Cu, In and Ag.
- 5. A slide member according to claim 1, wherein said Pb alloy contains 3% (inclusive) to 20% (inclusive) by weight of Sn.
- 6. A slide member according to claim 5 wherein said Pb alloy contains at most 10% by weight of at least one element selected from the group consisting of Cu, In and Ag.
- 7. A slide member comprising a surface layer of a Pb alloy on a slide surface for a mating member, wherein said Pb alloy has a crystal form with an orientation index in a (h00) plane by Miller indices being set in a range of 60 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.
- 8. A slide member according to claim 7, wherein the ratio h/d of the height h to the base length d of said pyramid is set in a range of 0.2 to 1.0.
- 9. A slide member according to claim 8, wherein said Pb alloy contains 3% (inclusive) to 20% (inclusive) by weight of Sn.
- 10. A slide member according to claim 9 wherein said Pb alloy contains at most 10% by weight of at least one element selected from the group consisting of Cu, In and Ag.
- 11. A slide member according to claim 7, wherein said Pb alloy contains 3% (inclusive) to 20% (inclusive) by weight of Sn.
- 12. A slide member according to claim 11 wherein said Pb alloy contains at most 10% by weight of at least one element selected from the group consisting of Cu, In and Ag.
- 13. A slide member according to claim 7, wherein said orientation index is greater than or equal to 97%.
