Abstract
Studies of assimilation of phosphorus in open-arc and submerged-arc (with fluxes AN-26 and AN-348) surfacing using flux-cored wires containing up to 2.5 % P, as well as tribological properties (sliding friction coefficient and wear resistance) and structure of deposited metal of the Fe-Cr-Si-Mn-P alloying system, were conducted. Almost all phosphorus was found to be assimilated by the deposited metal in surfacing by the flux-cored wire open-arc and submerged-arc (with fluxes AN-26 and AN-348) methods. It is shown that samples of the deposited metal alloyed with 0.9-1.2 % P have a minimum sliding friction coefficient, and a minimum wear of the sample and mating body is provided at a phosphorus content of 2.0 %
