Abstract

The invention relates to rare earth-zinc-nickel multi-element alloy anti-corrosion anti-fatigue electroplating liquid for a metal surface as well as a preparation method of the electroplating liquid.The method comprises the following steps: heating deionized water, adding zinc chloride, nickel chloride, boric acid, ammonium chloride and KCl, completely stirring until the materials are completelydissolved, adjusting pH, adding sodium benzenesulfonate or propargyl sodium sulfonate, and sodium benzoate, completely stirring, adding rare earth nitrate and completely stirring to prepare a mixed solution C; taking benzalacetone, o-chlorobenzaldehyde, butynediol, sulfonic acid-OP-10 and sodium lauryl sulfate, adding water and stirring to obtain a mixed solution D; adding polyethylene polyamine or polyethyleneimine into a mixed solution C, and adjusting the pH by using weak aqua ammonia or dilute hydrochloric acid to obtain a mixed solution E; mixing the mixed solution D and the mixed solution E and adding deionized water to a constant volume to obtain electroplating liquid. The rare earth-zinc-nickel multi-element alloy anti-corrosion anti-fatigue electroplating liquid for the metal surface as well as the preparation method thereof have the following advantages: the preparation method of the electroplating liquid is simple to operate, and higher corrosion resistance and fatigue resistance can be given to the metal surface.

Description

technical field [0001] The invention relates to a rare earth-zinc-nickel multi-element alloy anti-corrosion and anti-fatigue electroplating solution for metal surfaces and a preparation method thereof, in particular to a rare earth-zinc-nickel multi-element alloy anti-corrosion and anti-fatigue used for railway fasteners made of metal surface materials. Fatigue electroplating solution and preparation method thereof. Background technique [0002] The railway fastener is the connecting piece between the rail and the sleeper. Its function is to fix the correct position of the rail, prevent the longitudinal and lateral displacement of the rail, and prevent the rail from tipping over. The spring bar is one of the most important accessories in the fastener system. It mainly uses the energy stored during elastic deformation to alleviate mechanical vibration and impact. my country's railway fastener components such as elastic bars are generally made of spring steel, which must with...
