Abstract

The invention provides a Ce-Ni-B / GO chemical composite deposition layer and an ultrasonic-assisted preparation method thereof. The ultrasonic-assisted preparation method is prepared by the following step of carrying out ultrasonic treatment on a low carbon steel workpiece in Ce-Ni-B / GO composite deposition liquid to prepare the Ce-Ni-B / GO chemical composite deposition layer on the surface of low carbon steel, wherein in the composite deposition liquid, the composite deposition liquid per L is prepared from the following components in parts by weight: 0.1-5g of cerium, 20-55g of nickel chloride hexahydrate, 0.5-4g of sodium borohydride, 20-65g of sodium hydroxide, 15-65g of ethylenediamine, 0.1-2g of sodium dodecyl sulfate and 0.1-10g of graphene oxide. According to the ultrasonic-assisted preparation method, the multifunctional nano composite deposition layer on the surface of the low carbon steel based on an ultrasonic wave and chemical plating technology by adopting the composite deposition liquid; and the prepared composite deposition layer is capable of effectively improving the performances including the corrosion resistance, the surface hardness and the wear resistance of the low carbon steel and effectively solving the problem that particles crack.

Description

technical field [0001] The invention belongs to the technical field of inorganic materials, and in particular relates to a Ce-Ni-B / GO chemical composite deposition layer and an ultrasonic-assisted preparation method thereof. Background technique [0002] Electroless plating refers to a new type of surface treatment technology that adds an appropriate reducing agent to the plating solution to spontaneously reduce metal ions on the surface. Because no external power supply is needed, the cost is low, and the coating can be uniform and has a good decorative effect, it has begun to replace electroplating technology in many fields, and can be widely used in industries such as electronics, valve manufacturing, machinery and automobiles. [0003] In 1944, the discovery of A.Brenner and G.Riddell of the National Bureau of Standards clarified the catalytic properties of the coating and discovered the method of depositing non-powder nickel, which made it possible for the industrial ap...
