Detailed description of the invention
Embodiments of the invention are described below in detail, and the example of described embodiment is shown in the drawings, the most identical Or similar label represents same or similar element or has the element of same or like function.Retouch below with reference to accompanying drawing The embodiment stated is exemplary, it is intended to is used for explaining the present invention, and is not considered as limiting the invention.
In describing the invention, it is to be understood that term " first ", " second " are only used for describing purpose, and can not manage Solve as instruction or imply relative importance or the implicit quantity indicating indicated technical characteristic.Thus, define " first ", The feature of " second " can express or implicitly include one or more this feature.In describing the invention, " multiple " It is meant that two or more, unless otherwise expressly limited specifically.
In one aspect of the invention, the present invention proposes a kind of metallic matrix chemical plating pre-treating method, according to the present invention's Embodiment, the method includes: by Brush Plating, forms prime coat at metal base surface, wherein, prime coat contain nickel, Iron, palladium, aluminium, zinc at least one.Specifically, Brush Plating is a kind of new plating side grown up from groove coating technology Method, due to its low cost, technique is flexible, production efficiency is high, coating and base material bond strength high and uniformly, fine and close in engineering On be with a wide range of applications.Metallic matrix chemical plating pre-treating method according to embodiments of the present invention is by using Brush Plating Effectively can form activation site at metal base surface, thus follow-up carry out chemical plating process, the coating simultaneously prepared Crystallite dimension can reach nanoscale, and can meet the ability of the coating that processability is excellent on multiple base material.Meanwhile, Owing to the coating grain size of preparation is nanocrystalline level, can be to be intended to deposited plating layer as prime coat, it is provided that more row core basic point, Improve binding force of cladding material and deposition efficiency.
According to embodiments of the invention, with reference to Fig. 1-3, the concrete steps of Brush Plating include:
S100: activation process
According to embodiments of the invention, utilize activating solution that metal base surface is carried out activation process.Enforcement according to the present invention Example, the particular type of metallic matrix is not particularly restricted, and according to embodiments of the invention, metallic matrix can be by being selected from Copper, medium carbon steel, high-carbon steel, cast iron, stainless steel, magnesium alloy, aluminium alloy at least one.
Below with reference to Fig. 2, the step of activation process is described in detail.According to embodiments of the invention, this step includes:
S110: the first activation process
According to embodiments of the invention, utilize the first activating solution, carry out the first activation process at metal base surface.According to this Inventive embodiment, the condition carrying out the first activation process is not particularly restricted, according to a particular embodiment of the invention, the One activation process can complete under the voltage of 10~12 volts.Inventor finds, if overtension, matrix can be caused to corrode tight Weight, affects size and the surface property of matrix;And brownout, activation effect is undesirable, it is impossible to effectively remove matrix surface Oxide layer.According to embodiments of the invention, the composition of the first activating solution is not particularly restricted, concrete according to the present invention Embodiment, the first activating solution is the final concentration of 25.0ml/L of concentrated hydrochloric acid, the mixed solution of the final concentration of 140.1g/L of sodium chloride. Specifically, under the voltage of 10~12 volts, the speed with 5~10m/min carries out activation process to matrix in the first activating solution, By the time matrix surface oxide layer activation is fallen, and matrix surface color is homogeneous simultaneously, activates.Inventor finds, matrix is general Cross through machining, therefore there is oxide layer, fatigue layer at matrix surface, affect the combination of coating and matrix, Therefore the first activating solution is used can effectively to remove matrix surface oxide layer, fatigue layer, thus beneficially being smoothed out of brush plating.
S120: the second activation process
According to embodiments of the invention, utilize the second activating solution that the surface of the metallic matrix through the first activation process carries out Two activation process.According to embodiments of the invention, the condition carrying out the second activation process is not particularly restricted, according to this Bright specific embodiment, the second activation process can complete under the voltage of 14~18 volts.Inventor finds, overtension meeting Etched the matrix, too low further, causes cannot effectively removing the active layer that matrix surface is formed.Enforcement according to the present invention Example, the composition of the second activating solution is not particularly restricted, and according to a particular embodiment of the invention, the second activating solution is citric acid The final concentration of 141.2g/L of sodium, the final concentration of 94.2g/L of citric acid and the mixed solution of the final concentration of 3.0g/L of nickel chloride.Specifically Ground, under the voltage of 14~18V, (voltage can be according to the suitable regulation of different matrixes), with the activation of 4~10m/min Speed carries out the second activation process, waits until to dispose the active layer of back, and activation just can terminate, and soak time is about 10~20s, it is therefore an objective to remove back active layer, make matrix expose fresh matrix, improve the adhesion of matrix and coating.
S200: Brush Plating processes
