Imitation gold treatment of steel parts is a process that uses surface treatment technology to make steel products appear similar to gold color. It is often used in decoration, handicrafts, hardware accessories and other fields.
Imitation gold electroplating
Principle: Deposit a layer of imitation gold alloy (such as copper-zinc-tin alloy, copper-tin alloy, etc.) on the surface of steel by electroplating, and then protect it with passivation or transparent paint.
Steps:
Pretreatment: degreasing, pickling, activation (ensuring surface cleanliness).
Electroplating base: First plate copper or nickel as the base (improve bonding strength and gloss).
Imitation gold electroplating: Use imitation gold electroplating solution (such as Cu-Zn-Sn alloy), control pH, temperature, and current density.
Post-treatment: passivation (anti-oxidation), spraying transparent protective paint (such as UV paint, epoxy resin).
Advantages: realistic color and good wear resistance.
Disadvantages: professional equipment is required and environmental protection requirements are high (containing cyanide or cyanide-free electroplating).
