Abstract

The invention discloses an electric flat carriage which comprises a metal spindle, wherein the metal spindle is subjected to surface treatment. The surface treatment comprises the following steps: 1. taking 17 parts by mass of citric acid, 1-2 parts by mass of ethidene diamine, 1.6 parts by mass of boric acid, 3.1 parts by mass of calcium gluconate, 4.2 parts by mass of sodium molybdate, 1.2 parts by mass of sodium alkylarysulfonate, 2.4 parts by mass of phenyl naphthylamine and 1.6 parts by mass of sodium hypochlorite, mixing for 2 hours at the temperature of 75 DEG C so as to prepare a metal surface treatment agent; 2. mixing 26 parts by mass of the metal surface treatment agent with 47 parts by mass of deionized water so as to prepare a surface treatment working solution; and 3. heating the surface treatment working solution to 40 DEG C, and putting a metal shell into the surface treatment working solution for 35 minutes. According to the invention, the metal spindle is subjected to surface treatment, and the electric flat carriage has excellent performances of abrasion resistance, corrosion resistance, antioxidation, heat resistance, cold resistance and weather resistance.

Description

technical field [0001] The invention relates to an electric flat car. Background technique [0002] Existing electric flat car, the wear resistance, corrosion resistance, oxidation resistance, heat resistance, cold resistance, weather resistance performance of its metal main shaft need to be improved.
