Abstract
The invention discloses a brush plating technology of aluminum alloy. The technology comprises the following steps: polishing the surface, which will be subjected to brush plating, of an aluminum alloy by abrasive paper to remove the oxide scales; then carrying out cathode electrolysis under a voltage of 10-15 V for 10 to 20 seconds to remove the oil, washing the aluminum alloy by water; performing anode activation by using an activating liquid under a voltage of 12-16 V for 8 to 12 seconds to turn the surface of aluminum alloy into a dark grey color, washing the aluminum alloy by water, wiping the surface to be plated by an alkaline cooper plating solution in the absence of electricity; carrying out copper pre-plating through brush plating under a voltage of 8-10 V for 1 to 2 minutes, washing the aluminum alloy by water; carrying out tin plating through brush plating under a voltage of 8-12 V for 0.5 to 3 minutes, and washing the aluminum alloy by water to finish the brush plating. The technology has the advantages of simple steps and easy operation and control. The voltage and time of brush plating can be reasonably controlled to guarantee the quality of brush plating, the combination between the coating and the substrate is good, bubbling is not easy to happen, thus the corrosion on aluminum alloy is effectively prevented, and the technology is very practical.
Description
Technical field
The invention belongs to aluminium alloy processing technology field, be specifically related to a kind of brush-plating technique of aluminium alloy.
Background technology
Aluminum-aluminum alloy, because adding different alloying elements, can be present in aluminium alloy with several different form.As: the character entering aluminium with the form of sosoloid; Appear in aluminium alloy with the form of the micro-particle of element itself or the form of intermetallic compound particle that is made up of aluminium or other alloying element.So different aluminium alloys needs different pre-treatments and pre-plating process, a kind of general pre-treatment and pre-plating process be found to be very difficult.
Summary of the invention
In order to overcome the above-mentioned technical problem that prior art field exists, the object of the invention is to, provide a kind of brush-plating technique of aluminium alloy, technique highly versatile, coating is combined well with matrix.
The brush-plating technique of aluminium alloy provided by the invention, comprises following processing step: (1) with sand papering aluminium alloy brush plating surface, old fall oxide skin; (2) under the voltage conditions of 10-15V, catholyte deoils 10-20s, afterwards by clean for aluminium alloy washing; (3) adopt activation solution to carry out anode activation, voltage l2-16V, soak time is 8-12s, makes aluminum alloy surface be Dark grey, after washing, and with alkaline copper plating bath without electric wiping coating surface; (4) brush plating copper pre-plating, brushing plating voltage 8-10V, time l-2min, after washing clean; (5) brush plating tin, brushing plating voltage 8 ~ 12V, time 0.5-3min, after washing clean, complete brush plating.
The brush-plating technique of aluminium alloy provided by the invention, its beneficial effect is, processing step is simple, is easy to control, operate; Conservative control brushing plating voltage and time, guarantee brush plating quality, coating is combined with matrix well, not easy to foaming, and effectively prevent aluminium alloy from corroding, technique is practical.
Embodiment
Below in conjunction with an embodiment, the brush-plating technique of aluminium alloy provided by the invention is described in detail.
Embodiment
The brush-plating technique of the aluminium alloy of the present embodiment, comprises following processing step: (1) with sand papering aluminium alloy brush plating surface, old fall oxide skin; (2) under the voltage conditions of 12V, catholyte deoils 15s, afterwards by clean for aluminium alloy washing; (3) adopt activation solution to carry out anode activation, voltage l5V, soak time is 10s, makes aluminum alloy surface be Dark grey, after washing, and with alkaline copper plating bath without electric wiping coating surface; (4) brush plating copper pre-plating, brushing plating voltage 10V, time 90s, after washing clean; (5) brush plating tin, brushing plating voltage 10V, time 1min, after washing clean, complete brush plating.
