Abstract

The invention discloses a processing method for electroplating pretreatment. The method comprises the following steps of step 1, preparing a metamorphic loading agent; step 2, pre-activating a metal piece: activating the to-be-treated metal piece at the temperature of 210-250 DEG C for 20-30 minutes, then cooling the metal piece to 150 DEG C at the speed of 2 DEG C/min, and finally quenching the metal piece to room temperature by water; and step 3, treating the metamorphic loading agent. According to the method, the metal piece is firstly activated, and the activating treatment adopts 210 DEG C high-temperature, variable-temperature and water quenching treatment, so that the surface active performance of the metal piece is improved, the porosity of the surface structure of the metal piece is improved, and the subsequent modification treatment on the metal piece by the modification loading agent is facilitated.

Description

technical field [0001] The invention relates to the technical field of electroplating, in particular to a processing method for pretreatment of electroplating. Background technique [0002] Electroplating refers to a surface processing method in which the cations of the pre-plated metal in the plating solution are deposited on the surface of the base metal by electrolysis with the base metal to be plated as the cathode in the salt solution of the pre-plated metal to form a coating. The performance of the coating is different from that of the base metal and has new characteristics. According to the function of the coating, it is divided into protective coating, decorative coating and other functional coatings. Electroplating is an electrochemical process as well as a redox process. The basic process of electroplating is to immerse the part in a solution of metal salt as the cathode, and the metal plate as the anode, and then deposit the desired coating on the part after con...
