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 or spraying 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. The spray process can involve a twin-wire arc spray process or a high velocity oxy-fuel spray process.
