Enhanced bearing durability rotating member method and apparatus

摘要

Disclosed herein is a method of preparing a rotating member (10) to enhance bearing durability comprising, applying a metal material (12) to a surface (26) of the rotor (10) orthogonal to a longitudinal axis (16) of the rotor (10), the material (12) having a chromium content less than a chromium content of the rotating member (10), and surfacing said metal material (12) orthogonal to the axis (16) of the rotor (10). Further disclosed herein is an enhanced bearing durability rotating member (10) comprising, a rotor (10) with a metal material (12) surface (18, 22) orthogonal to a longitudinal axis (16) of the rotor (10) having less chromium content than the rotor (10), and a boundary layer (26) between the metal material surface (18, 22) and the rotor (10) orthogonal to the axis (16) of the rotor (10).
