Abstract:
A bushing formed of different alloys selected to accommodate different operating conditions is provided. For example, the bushing could include an iron-based alloy in a portion of the bushing exposed to lower temperatures, and a cobalt-based alloy in a portion of the bushing exposed to higher temperatures. The first and second alloys could be axially or radially aligned. The iron based alloy includes 10 to 30 wt % Cr, 0 to 21 wt % Ni, 0 to 10 wt % Mo, 0 to 5 wt % W, 0 to 3 wt % C, 0 to 4 wt % V, 0 to 20 wt % Co, and a balance of Fe; and the cobalt based alloy includes 10 to 30 wt % Cr, 5 to 21 wt % Ni, 0 to 10 wt % Mo, 0 to 10 wt % W, 0 to 3 wt % V, 0.5 to 3 wt % C, and a balance of Co.
