Embodiment 1
[0026] LEUCHSOL RGX commercial cutting fluid stock solution is mixed with deionized water at a mass ratio of 1:19 to obtain an emulsion; due to the selective adsorption of the surfactant contained in the cutting fluid stock solution, the outermost layer of oil droplets in the emulsion presents obvious charging characteristics, such as figure 1 shown;
[0027] Take 6 samples from the emulsion, measure the size of the oil droplets in the 6 samples with a Malvern nanometer, and calculate the average diameter D of the oil droplets in the emulsion to be 4 μm;
[0028] The Zeta potential of the solid-liquid interface between the emulsion and the surface of the SNMG 120408 cemented carbide tool produced by KENNAMETAL was measured by a Zeta potential meter. -72.3mV;
[0029] An electric double layer is formed between the emulsion and the tool surface, and the thickness of the electric double layer is calculated according to the following formula,

The invention relates to a surface texturing method for strengthening the lubricity of emulsion through an electric field and belongs to the field of the lubricating technology and the surface texturing technology. The surface texturing method comprises the steps that the sizes of oil drops in the emulsion and the distance between the Stern layer and the solid surface are used as design data of the texturing size of the solid surface, through the attraction force of the applied electric field to the charged oil drops in the emulsion, the oil drops in the emulsion are fixed in a surface texturewith the size being equivalent to the sizes of the oil drops, thus it can be guaranteed that the oil drops directly arrive at a friction contact area and an oil film does not fracture, the capacity that the oil drops form a boundary lubricating film or the bearing oil film is strengthened, the stability of the boundary lubricating film or the bearing oil film is strengthened, and the bearing capacity and the lubricating capacity of the boundary lubricating film or the bearing oil film are improved. The surface texturing method can be widely applied to surface antifriction treatment of cuttingcutters and the like under the emulsion environment.
Description
technical field [0001] The invention relates to a surface texture method for electric field enhanced emulsion lubrication, and belongs to the technical fields of lubrication technology and surface texture. Background technique [0002] Friction and wear in the machinery industry is the main factor causing surface failure, such as the surface wear and failure of components with obvious relative motion such as tools, bearings, and gears. The surface of the actual mechanical parts has a certain roughness. During friction, the actual contact area is only a small part compared with the apparent area, and the actual contact area is the micro-area of rough surface. When the contact surface moves relative to each other, the load is only distributed in a limited contact area, so that there is obvious extrusion, friction and high temperature on the friction surface. The wear is due to the mechanical action of friction force, the high temperature thermal softening effect of friction ...
