  • PLAIN BEARING BETWEEN TWO PARTS WHICH ARE MOVABLE WITH RESPECT TO EACH OTHER
    Publication number: 20060237100
    Abstract: The present invention relates to a plain bearing between two parts movable with respect to each other, the first part having a first bearing element made from a first metal and the second part having a second bearing element made from a second metal of higher hardness. The bearing is characterized in that the first bearing element 107-108; 204-205; 307-308-313; 414-413 has a surface layer hardened by strain hardening. As a result of the invention, the wear between the parts is reduced and their life is substantially lengthened. The invention can be advantageously applied to cases in which the first part is a variable-setting diffuser blade and the second part is a gas turbine casing.
