Embodiment 1

[0016] 64.80g (0.5mol) NiCl 2 , 0.5g of cetyltrimethylammonium bromide (CTAB) were dissolved in deionized water, heated to 70°C in a water bath, and 1ml of paraffin liquid was slowly added to the solution while ultrasonically stirring in a constant temperature tank, After cooling to room temperature to form an emulsion, with NiCl 2 After the solutions were mixed, the volume was fixed in a 1L volumetric flask as an electrodeposition solution, and the electrodeposition solution was a green solution with milky white suspension droplets. Cut the copper flake base into 2cm×3cm small pieces, then immerse in dilute hydrochloric acid to remove the surface oxide layer, and ultrasonically clean them in deionized water and acetone for 5 minutes each. Wires are connected after cleaning to make electrodes, which are deposited in a standard three-electrode electrochemical workstation after immersion in an electrodeposition solution. Select the initial deposition voltage -0.5V, and the dep...

Abstract

The invention discloses a method for preparing a nickel-based paraffin self-lubricating composite plating layer, which belongs to the technical field of composite materials. The method comprises the following steps of: preparing a surfactant emulsion containing paraffin, and uniformly mixing the surfactant emulsion and nickel salt solution to form electrodeposition solution; and adopting an electrodeposition method to prepare the nickel-based paraffin self-lubricating composite plating layer. The method realizes 'solid-liquid synergistic friction' through simple steps, and even the paraffin runs off in the friction process, paraffin particles in a composite material can be supplemented continuously, so the service life of the composite material is greatly prolonged.

Description

technical field [0001] The invention relates to a method in the technical field of composite materials, in particular to a method for preparing a nickel-based paraffin self-lubricating composite coating. Background technique [0002] In material science, friction has many hazards. Lubrication is an important means to solve friction problems, and it is of great significance to save energy and reduce emissions. There are many disadvantages in the traditional way of adding lubricants, so metal matrix composites with self-lubricating properties have many advantages that traditional lubrication methods cannot match, such as smaller friction coefficient, more energy-saving and environmental protection, and longer service life. There are two types of self-lubricating materials, one is the composite of metal and solid lubricant, and the other is adding lubricating oil to the porous matrix. However, due to the physical properties of metal and lubricating oil two-phase materials, it ...
