Electroplating process for irregular metal workpiece

Abstract

An electroplating process for an irregular metal workpiece is characterized by comprising the following steps: a deoiling step: deoiling the metal workpiece by using a deoiling device, and then cleaning to complete the manufacturing of a primary metal workpiece; an activation step: putting the primary metal workpiece into an activation tank for soaking, and then washing with water to complete the manufacturing of an activated metal workpiece; an electroplating step: electroplating the activated metal workpiece to complete manufacturing of an electroplated metal workpiece; and a drying step: carrying out passivating treatment on the electroplated metal workpiece, and then carrying out washing and drying treatment so as to complete the manufacturing of a finished product. The pretreatment effect on the metal workpiece can be further improved, and then the effect of improving the electroplating machining quality of the metal workpiece is achieved.

Description

technical field [0001] The invention relates to the technical field of electroplating equipment, in particular to an electroplating process for irregular metal workpieces. Background technique [0002] The method of plating a layer of nickel on metal or some non-metal by electrolysis or chemical method is called nickel plating. Nickel plating is divided into electroplating nickel plating and chemical nickel plating. Nickel electroplating is in an electrolyte composed of nickel salt (called main salt), conductive salt, pH buffer, and wetting agent. The anode uses metallic nickel, the cathode is the plated part, and direct current is applied to the cathode (plated part). Deposit a uniform and dense nickel coating. The electroplating process is roughly the same, generally including three main stages: pre-plating pretreatment, electroplating and post-plating treatment. The existing technical solutions only simply use hot water immersion degreasing and pickling activation in t...

AI Technical Summary

Problems solved by technology

The existing technical solutions only simply use hot water immersion degreasing and pickling activation in the pretreatment process of electroplated workpieces. The degreasing ability of hot water is poor and the grease and organic impurities on the surface of the workpiece cannot be well removed. However, the grease and organic impurities on the surface of the workpiece will affect the activation of the pickling solution on the surface of the workpiece, thereby affecting the combination of the coating and the workpiece. The residual grease and organic impurities on the surface of the workpiece will easily lead to needles on the surface of the workpiece during electroplating. Holes and burrs, and may cause peeling of the coating, affecting the quality of the electroplating process of the workpiece
