Abstract

The invention discloses a nitrogen-rich water-based enhanced superfinishing method for the alloy workpiece surface and a formula of superfinishing liquid. The superfinishing liquid is prepared from anitrogen-rich water-based superfinishing concentrated solution and water, wherein the nitrogen-rich water-based superfinishing concentrated solution contains 25-30% by mass of mixed extreme pressure additive and 5-10% by mass of penetrant mixture; the mixed extreme pressure additive is prepared from the following raw materials in percentage by mass: 10-20% of fatty acid imidazoline borate, 3-5% ofrosin amide, 3-6% of polyethylene glycol alkyl ether and the balance of water; and the penetrant mixture is a mixture of ethylenediamine tetraacetic acid disodium salt, rare earth compound and ethanol according to any proportion. The nitrogen-rich water-based enhanced superfinishing method adopts nitrogen-rich water-based superfinishing liquid without kerosene, and fine-grained oil stone installed on a vibrating head is utilized to finish the finished surface, so that the process is simple, the operation is easy, the efficiency is high, and the nitrogen-rich water-based enhanced superfinishing method for the alloy workpiece surface and the formula of superfinishing liquid are suitable for large-scale mass production.

Description

Technical field [0001] The invention belongs to the field of superfinishing on the surface of an alloy workpiece, and specifically relates to a nitrogen-rich water-based strengthening superfinishing method on the surface of an alloy workpiece and a superfinishing fluid formula. Background technique [0002] Metal material surface processing technology (especially surface ultra-precision modification technology) can greatly improve the strength, wear resistance and fatigue life of materials, and has been widely used in the processing of mechanical parts. [0003] The prior art has disclosed many related technologies for surface modification of metal materials. Among them, the plasma injection method is currently the most widely used metal material surface modification technology. The invention patent CN102191454B of Liu Xuanyong et al. discloses a method for surface modification of medical titanium metal materials. A composite plasma injection process is used to inject metallic or ...
