Problems solved by technology

The conventional electroplating wear-resistant layer is to plate a layer of metal nickel Ni or metal chromium Cr on the substrate to improve the wear resistance of the substrate material, but the metal chromium Cr is a heavy metal, which is harmful to the human body
And for the application industry with relatively high wear resistance requirements, a single layer of metal nickel Ni coating or a single layer of metal chromium Cr coating can not meet its requirements for wear resistance, so research and development of a high wear resistance, thermal conductivity The highly resistant coating has a good market application prospect

Embodiment 1

[0024] The preparation of embodiment 1 nano-diamantene

[0025] Nanodiamondene was prepared by the following method:

[0026] (1) Preliminary crushing: Send the diamond raw material into the ball mill shaping barrel to crush and screen out the particles above 70 mesh. The crushing time is 1~5 hours. The coarse material below 70 mesh is returned to the ball mill shaping barrel for re-crushing; The sieve machine sieves out fine materials with a mesh size of 800 mesh or more, and the vibrating time is 30 minutes to 2 hours, and the fine materials are repeatedly sieved more than once;

[0027] (2) Re-crushing: The fine material above 800 mesh screened is transported to the air flow crusher, the fine material is crushed by high-pressure airflow, and the fine powder above 8000 mesh is screened out, and the sieved residue is returned to the air flow crusher for re-crushing ;

[0028] (3) Pickling: First, put the fine powder above 8000 mesh in the mixture of concentrated sulfuric ...

Abstract

The invention discloses a composite electroplating technology of high-wear-resisting nano diamond alkene, and belongs to the field of electroplating technologies. The method comprises following steps: firstly, electroplating liquid is prepared, a nickel aminosulfonate stock solution, a boric acid aqueous solution and a nickel chloride aqueous solution are mixed and stirred, and heated to 55 DEG C to 60 DEG C, then, lauryl sodium sulfate, saccharin and 1,4-butynediol are added, and electroplating liquid is prepared; nano diamond alkene is added; the nano diamond alkene is ultrasonically dispersed for 2 h in the electroplating liquid, then, composite electroplating liquid is obtained, and the composite electroplating liquid is slowly added into an electroplating bath in batches; thirdly, electroplating is carried out, a cleaned-up to-be-electroplated workpiece is placed in the composite electroplating liquid at the temperature of 55 DEG C to 60 DEG C, the to-be-electroplated workpiece serves as a negative electrode, a pure nickel plate serves as a positive electrode, the electroplating liquid is stirred, and electroplating current of 1-3A / dm<2> is applied; and after electroplating is finished, and an electroplating part is obtained. The thickness of an electroplating layer is reduced, the requirement for heavy metal is reduced, the pollution to the environment is reduced, and hardness, wear resistance and corrosion resistance of the electroplating layer can be obviously improved.

Description

technical field [0001] The invention belongs to the field of electroplating processing technology, and in particular relates to a highly wear-resistant nano-diamondene composite electroplating technology. Background technique [0002] Electroplating is a process of plating a layer of metal deposition layer on the surface of the plated part by electrochemical method, which belongs to a kind of surface treatment process. Electroplating is used for surface treatment, and usually has two functions: to give or improve the surface state of the product or to make the product surface have some special function. As a traditional surface treatment process, electroplating has long been used to provide a protective decorative coating or a functional coating that changes the surface properties of the base material. [0003] With the continuous development and progress of my country's science and technology, electroplating has been used in high-end industries such as aerospace, solar cel...
