Description of the invention: [Technical field to which the invention pertains] A surface treatment method for a metal, in particular, a metal surface treatment method which can improve the lubricity of a metal surface. [Prior Art] The treatment of the metal surface is usually caused by various factors depending on the application range of the component to be processed. In the case of a toothed disc commonly used in bicycles for driving a chain, in practical applications, due to scattered sand dust, most of them will fall on the surface of the toothed disc, which will cause wear on the surface of the toothed disc over time; When the disc is running, the user usually needs to add lubricating oil to reduce the frictional resistance between the toothed disc and the chain, and further make the toothed disc run smoothly. However, since the added lubricating oil will absorb sand dust more easily, it is for the toothed disc. The surface design still needs to be improved. Another example is a vacuum chuck for adsorbing a liquid crystal screen, which has a flat adsorption surface, and a vacuum nozzle on the adsorption surface, and an existing design on the suction surface of the vacuum suction cup. In addition to making the suction cup have a more resistant surface, it can also quickly dissipate the static electricity by using the conductive property of the plating layer to reduce the fragmentation failure when the substrate and the suction cup are separated. However, in practical applications, vacuum nozzles often appear. After the vacuum is released, the liquid crystal screen is still adsorbed on the adsorption surface of the vacuum chuck, so that the liquid crystal screen cannot be surely lowered to a predetermined position in operation, and therefore the surface treatment of the vacuum chuck needs to be improved. SUMMARY OF THE INVENTION 5 200813264 The main object of the invention is to provide a metal surface treatment method which reduces the surface friction coefficient of the processed component. For the purposes of the foregoing, the present invention comprises: a. Thermal degreasing, subject to thermal degreasing treatment; b. Ultrasonic thermal degreasing, where the component is subjected to thermal degreasing and softening of the grease while simultaneously removing the grease by ultrasonic vibration. c·Washing, rinsing the surface of the component with water; d·neutralizing, immersing the component in an acidic solvent; • e·washing, re-rinsing the component with water; f. activating, treating the component in an activated manner g· pure water washing, the component is washed again with water; h. chemical nickel treatment, treated with chemical nickel and forming a chemical nickel layer; i· composite nickel Teflon layer, electroless plating on the surface of the chemical nickel layer Set the composite nickel-iron gas dragon layer; j. Wash the water with pure water, rinse the components again with water; k. Ultrasonic hot pure water wash, rinse the components with hot water again; _ · 1. Blow dry, blow the components with the wind Dry; m. Heat treatment 5 to warm the components. Of course, the invention may be varied on certain components, or in the arrangement of the components, but the selected embodiments are described in detail in the specification and their construction is shown in the drawings. [Embodiment] Please go through the first figure. The metal surface treatment method of this embodiment is as follows: 6 200813264 ι thermal degreasing, the components are subjected to thermal degreasing treatment; b. ultrasonic thermal degreasing, the components are subjected to thermal degreasing and softening treatment At the same time, ultrasonic vibration is used to remove the grease from the component; c·washing, rinsing the surface of the component with water; d·neutralizing, immersing the component in an acidic solvent; e. washing with water, rinsing the component with water again L activation, the component is treated in an activated manner; g· pure water is washed, the component is washed again with water; h·chemical nickel treatment, treated with chemical nickel and forming a chemical nickel layer; i· composite nickel Teflon layer , the composite nickel-iron-fluoride layer is set on the surface of the chemical nickel layer by electroless plating; j. pure water washing, the component is washed again with water; k· ultrasonic hot pure water washing, the component is washed again with hot water; Blow dry, dry the component with air; m heat treatment to warm the component, in this example the temperature is set to 180 degrees for 3 hours. Since the surface of the element after the treatment has a composite nickel-iron fluorocarbon layer, the sliding property is improved, and the abrasion resistance and the property name are greatly increased. In the case of the bicycle toothed disc, if the metal surface treatment method of the present invention is adopted, the composite nickel-iron-fluoride layer formed on the surface of the toothed disc can effectively reduce the dust adhering to the toothed disc and help to improve the shifting speed. Smoothness, and the composite nickel-iron fluorocarbon layer also provides good self-lubrication of the chainring. For the processing of the vacuum chuck, the composite nickel-iron-fluoride layer of the invention can also ensure that the liquid crystal screen can be separated from the adsorption surface 7 200813264 after the vacuum of the vacuum nozzle is released, and the positioning effect is maintained. The above description of the embodiments is intended to be illustrative of the invention, and is not intended to limit the scope of the invention. From the above detailed description, it will be apparent to those skilled in the art that the present invention can achieve the above-mentioned objects, and is in accordance with the provisions of the Patent Law.
