Abstract： |
The invention discloses a nickel-based composite plating layer containing nano diamonds and an ultrasonic auxiliary preparation method for the plating layer. The invention relates to the nickel-based composite plating layer and the preparation method of the plating layer. The nickel-based composite plating layer containing nano diamonds is with metal nickel or nickel alloy as the matrix, and nano diamond grains evenly diffused in. The preparation method includes the following procedures: preparation of the nano composite bath liquid: the nano composite plating layer is prepared in ultrasonic wave. In the plating layer, the nano diamond grains are evenly diffused in the nickel matrix in nano scale, so as to refine the metal grains and obviously improve the hardness and tribological performance of the original nickel plating layer. The invention uses ultrasonic cavitation to make sure of even scattering of the nano diamonds in the bath solution and plating layer, and promotes the codeposition of the nano grains and the metal. The nano composite plating layer can effectively improve the anti-abrasion and abrasion reduction performances of the surface of work pieces, extend the service life of them, and is widely applicable to easily wearable work pieces, such as moulds, all bearings, gears, engines, drive parts, etc. |
