The present invention provides alloy plating solution and corresponding treating process for producing oil well pump capable of resisting high temperature corrosion and high temperature wear, and with low cost and low power consumption. The alloy plating solution is compounded through dissolving nickel sulfate, amino acetic acid, amino borane, graphite fluoride, boric acid, sodium saccharin, lead ion, ammonia water and sodium hydroxide in the weight ratio of 3 to 2.5 to 0.45 to 0.6 to 3 to 0.3 to 0.003 to 0.35 to 0.15 in pure water of 90 weight portions. During plating, the alloy plating solution is heated to 40-60 deg.c, and the plating time is determined based on thickness to be plated. |
