耐摩耗性の鉛フリー合金摺動エレメントおよびその製造方法
Document Type and Number:
Japanese Patent JP2014505161
Kind Code:
A
Abstract:
A sliding element 20, such as a bushing or bearing, includes a sintered powder metal base 24 deposited on a steel backing 22. The base 24 includes a tin, bismuth, first hard particles 40, such as Fe3P and MoSi2, and a balance of copper. In one embodiment, a tin overplate 26 is applied to the base 24. A nickel barrier layer 42 can be disposed between the base 24 and the tin overplate 26, and a tin-nickel intermediate layer 44 between the nickel bather layer 42 and the tin overplate 26. In another embodiment, the sliding element 20 includes either a sputter coating 30 of aluminum or a polymer coating 28 disposed directly on the base 24. The polymer coating 28 includes second hard particles 48, such as Fe2O3. The polymer coating 28 together with the base 24 provides exceptional wear resistance over time.
