Abstract

A method for preparing an anode made of a copper-phosphorus alloy comprises the following steps in sequence: preheating an ingot made of the copper-phosphorus alloy; forging the ingot; conducting homogenized annealing treatment on the ingot; conducting cold rolling on the ingot to form a blank; conducting recrystallization annealing treatment on the blank; and machining the blank, so as to form the anode made of the copper-phosphorus alloy. According to the method, the combination of repeated plastic deformation with a specific deformation rate and annealing treatment under specific temperature is mainly adopted, and the deformation rate of the plastic deformation, the temperature during the annealing treatment, and the time of the annealing treatment are controlled, so as to produce the anode meeting the requirements on compact and uniform internal structure and no lamination for electroplating.

Description

technical field [0001] The invention relates to the field of electroplating, in particular to a method for preparing a copper-phosphorus alloy anode for electroplating. Background technique [0002] Electroplating is the process of plating a thin layer of other metals or alloys on some metal surfaces using the principle of electrolysis. It uses the principle of electrolysis to attach a layer of metal film to the surface of metal or other material parts, so as to prevent corrosion, improve wear resistance, conductivity, reflectivity and enhance the appearance. [0003] In the plating tank filled with electroplating solution, the cleaned and specially pretreated parts to be plated are used as the cathode, and the plated metal is used as the anode, and the two poles are respectively connected to the negative and positive poles of the DC power supply. The electroplating solution is composed of an aqueous solution containing metal plating compounds, conductive salts, buffers, pH...
