sliding element, and method for forming a sliding element. a sliding element 20, such as a bearing or bushing, includes a sintered powder metal base 24 deposited on a steel support 22. base 24 includes a tin, bismuth, first hard particles 40 such as foil mosi ~ 2 ~, and a copper balance. In one embodiment, a tin overlay 26 is applied to the base. a nickel barrier layer 42 may be disposed between the base 24 and the tin overlay 26, and the tin overlay 26. in another embodiment, the sliding element 20 includes either an aluminum cathode coating 30 or a polymer coating 28 disposed directly to base 24. polymeric coating 28 includes second hard particles 48, such as fe ~ 2 ~ o ~ 3 ~. polymeric coating 28 along with base 24 provides wear resistance over time. |
