Metal material surface electrolytic texturing method

Abstract

The invention discloses a metal material surface electrolytic texturing method. The method comprises the following steps that S1, a high-molecular polymer electrolytic medium is guided to a to-be-processed area on a surface of a workpiece of a metal material through an electrolyte guiding spray head, so that a space between a tool electrode and the surface of the workpiece is filled with the high-molecular polymer electrolytic medium; and the high-molecular polymer electrolytic medium is one or more of polyacrylamide hydrogel, sodium carboxymethylcellulose hydrogel or polyvinyl alcohol hydrogel; and S2, voltage is applied between the tool electrode and the surface of the workpiece by using a power supply for electrolytic reaction, and the workpiece with the textured surface is obtained after the electrolytic reaction is completed. According to the metal material surface electrolytic texturing method, a special high-molecular polymer is adopted as the electrolyte, locality is good, thetexturing effect is uniform, the morphology in a texturing area is controllable, texturing of any complex surface or any specific position of the complex workpiece surface can be achieved, the energyutilization rate can be increased, and the method is an environment-friendly texturing method.

Description

technical field [0001] The invention relates to the technical field of surface roughening of metal materials, and more particularly relates to a method for electrolytic texturing of metal material surfaces. Background technique [0002] Metal materials are widely used in the manufacturing industry. According to the performance requirements of different products, the surface of the workpiece made of metal materials not only needs to have good strength, hardness, rigidity, wear resistance, corrosion resistance, and sometimes good flow stamping properties , coating, light absorption, wave absorption, etc. After the surface of the metal material workpiece is roughened, the above-mentioned properties can be satisfied, so the surface roughening process is flourishing in the manufacturing industry. [0003] Surface texturing technology belongs to the category of surface engineering and is a specific application branch of surface technology. The textured surface refers to the work...
