Processing method of cylindrical component with mask micro-structure on outer curved surface

Abstract

The invention discloses a processing method of a cylindrical component with a mask micro-structure on the outer curved surface, which belongs to the field of electrochemical machining. The method comprises the following steps: imaging the surface of a curved-surface part through dipping, glue coating and rolling lithography or processing a planar flexible insulation shielding thin film with laser and fixing the thin film on the surface of the curved-surface part, and carrying out micro electrolytic machining with a cylindrical part as the anode and a sleeve as a cathode, thereby forming a micro structure on the curved surface. The method solves the manufacturing problem of the curved-surface part with the outer surface of a complex fine microstructure, and can be used for processing large-area curved-surface microstructures, in particular microstructures with complex patterns and small sizes. The curved-surface microstructures processed by the invention have the advantages of large processing area and high processing accuracy. The invention has the advantages of capability of processing microstructures with complex patterns and small sizes, simple operation, high efficiency and low processing cost.

Description

technical field [0001] The processing method of the cylindrical part with mask microstructure on the outer curved surface of the invention belongs to the field of electrochemical processing. Background technique [0002] With the development of science and technology, solving the problem of increasing energy shortage has become a research hotspot for workers from all over the world. Reducing friction and improving energy efficiency has always been the goal pursued by tribologists. According to traditional tribological research, the smoother the two surfaces in contact with each other, the smaller the friction coefficient and wear amount. In recent years, studies have shown that the smoother the surface, the more wear-resistant it is, but a certain non-smooth shape, that is, the surface with surface texture has better wear resistance. The so-called surface texture refers to the array of microstructural patterns such as pits, grooves or convex hulls with a certain size and ar...
