Abstract

The invention relates to a micro-pit array electrolysis system and method based on a dual-layer mold plate and a mold plate preparing method, and belongs to the field of minuteness electrolytic machining. The method comprises the steps of a, manufacturing a cathode tool (6) and a clamp (5); b, manufacturing a dual-layer mold plate (9) with a through hole array; c, attaching the dual-layer mold plate (9) to the upper surface of an anode workpiece (4), and using the clamp (5) to enable the cathode tool (6), the anode workpiece (4) and the dual-layer mold plate (9) to be clamped together; d, enabling the anode workpiece (4) and the cathode tool (6) to be connected with a positive electrode and a negative electrode of a power source (8) correspondingly; e, leading electrolytes (7) to the clamp (5), wherein the pressure intensity of the electrolytes is larger than 0.4 MPa; f, switching on the power source (8), and performing electrolyte machining. The method is adopted for carrying out electrolyte machining, rigidity of the epoxy resin mold plate is used, machining stability of a micro-pit array is improved, flexibility of a PDMS mold plate is used for promoting the PDMS mold plate to be tightly attached to the surface of an anode workpiece, and machining precision is improved.

Description

[0001] The invention relates to a micropit array electrolysis system and method based on a double-layer template and a template preparation method, belonging to the field of micro electrolytic processing. Background technique [0002] There are many kinds of friction pairs in the operation of mechanical devices. The tribological behavior of these friction pairs affects the working performance of the mechanical system, and in severe cases, it will lead to failure of parts. Studies have shown that the micropit array can improve the friction and wear performance of the surface of the friction pair, reduce friction, reduce wear, and increase the service life of the friction pair. Reasonable micropit array structure can store lubricating oil, form a good oil film, and improve the lubrication effect and wear resistance of friction pairs. At the same time, the friction pair will produce some wear debris during the relative motion, and some tiny particles from the outside will enter t...
