Abstract

The invention discloses a chromium plating method for a metal base material, and belongs to the technical field of electroplating. The method comprises the steps a, the surface of the metal base material undergoes oil removal and rust removal , and then the surface of the metal base material is cleaned and polished; b, an electroplating solution is prepared, the electroplating solution comprises,by weight, 20-30 parts of chromium chloride, 10-20 parts of chromium sulfate, 5-10 parts of zinc nitrate, 20-30 parts of sodium phosphate, 1-5 parts of dibutyltin diacetate, 1-5 parts of a complexingagent, 1-3 parts of oxalic acid, 1-3 parts of methanol, 1-5 parts of a buffering agent, 1-5 parts of ethane and 80-100 parts of deionized water; and c, after the electroplating solution is stirred for1-2 hours, the metal base material obtained from the step a is immersed in the electroplating solution, and the temperature of the electroplating solution is 30-40 DEG C. The binding force between the plating and the metal base material is strong, the wear resistance and the corrosion resistance of the plating are enhanced, and the service life and performance are improved.

Description

technical field [0001] The invention relates to the technical field of electroplating, in particular to a method for chrome plating of metal substrates. Background technique [0002] Metal materials such as metal substrates are usually electroplated on the surface for rust prevention and wear resistance, which has high hardness, excellent wear resistance, corrosion resistance and surface decoration to improve the corrosion resistance and wear resistance of steel substrates. , surface hardness and decoration. However, the current electroplating method needs to improve the wear resistance and corrosion resistance of the coating, so it is necessary to study new surface electroplating treatment methods and electroplating solutions to improve the bonding force between the coating and the metal substrate and enhance the wear resistance of the coating. and corrosion resistance. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a chrome plating...
