Abstract

A cylinder inner wall network oil storage structure manufacturing method comprises the steps of firstly preparing an alloying-like solution, performing preparation of an alloying solution, pre-preparing an alloying-like coating, adopting an immersion preset mode to immerse all cylindrical workpieces into the alloying solution, lifting out the cylindrical workpieces and then clamping the cylindrical workpieces on a chuck to perform rotation, enabling the laser surfaces of cylinder inner walls to be alloying, then performing network texturing laser etching and finally adopting fluid polishing finishing to conduct streamline finishing on the laser texturing surfaces. The problem of boundary texturing of an oil storage channel is solved, the problem that the roughness of the inner surface of a cylinder sleeve is improved due to modification is solved, and the surface smoothness reaches Ra 0.8 after fluid polishing. By means of the cylinder inner wall network oil storage structure manufacturing method, the problem that the abrasion resisting performance of the inner walls of the cylindrical workpieces is poor, the inner wall lubricating condition of the cylindrical workpieces is improved, and the service life of the cylindrical workpieces is prolonged.

Description

technical field [0001] The invention belongs to the technical field of oil storage on the inner wall of a cylindrical structure, and in particular relates to a method for preparing a network oil storage structure on the inner wall of a cylindrical structure. Background technique [0002] The oil storage modification technology of the inner wall of the cylindrical structure originated in Germany at the beginning of this century. It is mainly to process micro-pits with a certain regular shape on the surface of the friction pair, which can improve the surface friction characteristics, lubrication and wear resistance. It has been used in aviation abroad. , petrochemical, shipbuilding, automobile manufacturing and other industries in the surface treatment of cylinders, in order to improve the anti-wear and lubricating properties of the cylinders and thus improve the service life of the cylinders. The wear-resisting and lubricating performance of the engine has been greatly improv...
