Abstract
In one aspect, composite preforms are provided for imparting wear resistance to superalloy articles. The composite preforms can be employed for metallurgically bonding alloy wear plates or pads to superalloy articles. A composite preform, in some embodiments, comprises a powder alloy composition comprising 1-30 wt. % nickel, 0.05-2 wt. % iron, 15-25 wt. % chromium, 10-30 wt. % molybdenum, 0-1 wt. % carbon, 1-5 wt. % silicon, 0.05-2 wt. % boron, 0-5 wt. % tungsten, 0-3 wt. % tantalum, 0-0.1 wt % manganese, 0-3 wt. % aluminum, 0-0.1 wt % yttrium and the balance cobalt.
