Cu—Ni—Sn alloy overlay for bearing surfaces on oilfield equipment

摘要

A bearing surface of an oilfield component is treated by applying a surface treatment having a low coefficient of friction to the bearing surface of the oilfield component by weld fusing an overlay of a Cu—Ni—Sn alloy material to the bearing surface. Weld fusing the overlay of the Cu—Ni—Sn alloy material to the bearing surface can involve laser surface cladding the overlay of the Cu—Ni—Sn alloy material to the bearing surface, gas tungsten arc welding the overlay of the Cu—Ni—Sn alloy material to the bearing surface, or plasma tungsten arc welding the overlay of the Cu—Ni—Sn alloy material to the bearing surface.
