Problems solved by technology

Although composite electroplating can obtain the comprehensive properties of two kinds of matrix metals and solid particles, and has the characteristics of high performance and multifunctionality that ordinary electroplating does not have, but because the solid particles are very small, they are usually in a state of agglomeration in the natural state, resulting in Uneven plating on the metal surface
In order to meet the needs of industrial applications, the material must be subjected to secondary polishing processing, but this processing often destroys the material structure of the coating, resulting in a greatly reduced corrosion resistance of the material

Abstract

The aluminum and the aluminum alloy have the advantages of being small in volume weight, high in specific strength, good in atmospheric corrosion resistance, good in thermal conductivity, easy to form and process, capable of being recycled and the like, and the use amount of the aluminum and the aluminum alloy becomes a second major metal material only second to steel. Due to the fact that the mechanical strength and corrosion resistance of the surfaces of the aluminum and the aluminum alloy are weak under the natural condition, people usually plate a layer of metal nickel film on the surfaces of the aluminum and the aluminum alloy in an electroplating mode, and therefore the purposes of improving the mechanical strength and corrosion resistance of the aluminum and the aluminum alloy are achieved. Compared with a common electroplated layer, the composite electroplated layer has the advantage that the mechanical property is obviously improved generally. If particles with special performance are introduced, the composite electroplated layer may have functions which cannot be possessed by a common electroplated layer. High performance and multi-functionalization are important characteristics of composite electroplating performance. The method has important significance on wider industrial application of aluminum and aluminum alloy.

Background technique [0002] Aluminum and aluminum alloys have the advantages of small bulk density, high specific strength, good atmospheric corrosion resistance, good thermal conductivity, easy forming and processing, and recycling. Their consumption has become the second largest metal material after steel. Because the mechanical strength and corrosion resistance of aluminum and aluminum alloy surfaces are relatively weak under natural conditions, people usually coat a layer of metal nickel film on the surface by electroplating, so as to improve the mechanical strength and corrosion resistance of aluminum and aluminum alloys. the goal of. Compared with ordinary electroplating layers, composite electroplating usually has obvious improvement in mechanical properties. If particl...
