Abstract

The invention discloses an aero seat precision part surface treatment method, relates to the technical field of part surface treatment and aims at solving the problem that the environment is noisy due to high noise during existing part surface treatment and polishing. The aero seat precision part surface treatment method comprises the following steps of step 1, firstly, putting an aero seat precision part in alkali liquor; step 2, putting the aero seat precision part subjected to oil removal in hot water for further cleaning; step 3, putting the cleaned aero seat precision part in hydrochloric acid rust removal liquid; step 4, putting the aero seat precision part subjected to rust removal in cold water; step 5, putting the cleaned aero seat precision part in a sodium salt solution; step 6, putting the aero seat precision part subjected to ultrasonic cleaning in cold water; step 7, conducting polishing treatment on the cleaned aero seat precision part; and step 8, putting the polished aero seat precision part in an electrolyte to serve as an anode, and conducting electrolysis under the specific conditions and under the action of an external current.

Description

technical field [0001] The invention relates to the technical field of parts surface treatment, in particular to a method for surface treatment of precision parts of aviation seats. Background technique [0002] Surface treatment is a method of artificially forming a surface layer on the surface of the base material with different mechanical, physical and chemical properties from the base. The purpose of surface treatment is to meet the corrosion resistance, wear resistance, decoration or other special functional requirements of the product. , for metal castings, our more commonly used surface treatment methods are mechanical grinding, chemical treatment, surface heat treatment, surface spraying, surface treatment is to clean, sweep, deburr, degrease, descale, etc. on the surface of the workpiece, chemical treatment It mainly uses acidic or alkaline solution to chemically react with the oxide and oil on the surface of the workpiece, so that it can be dissolved in the acidic ...
