Definitions
- the present invention has for its object a process which makes it possible to obtain on aluminum and its alloys, sound electrolytic deposists which adhere firmly, resist corrosion well, are free from blisters or other defects and, moreover, are capable of taking a very high lustre.
- aluminum or an alloy of this metal after having been degreased and pickled according to a known method, is treated with an alkaline zincate solution, containing an alkali cyanide and copper cyanide.
- This treatment which has for a result the formation of a highly adherent, homogeneous, fine-grained zinc deposit, can be carried out electrolytically, but it is preferable to produce it by simple immersion.
- alkaline zincate solution may be prepared in ditferent ways, it is best that its composition be comprehended Within the following limits:
- the caustic soda may be replaced by potash and the KCN by NaCN.
- the copper may be replaced in part or in whole by another heavy metal capable of forming a cyanide complexi. e. a double cyahide-for example, by silver or cadmium.
- the concentration of the CuCN should not exceed Mt that of KCN.
- Another feature of the process, according to the present invention resides in the use of slightly acid nickelplating baths having a high concentration of strong electrolytes, preferably sulfates, for nickel-plating electrolytically the articles which have been zinc-plated in accordance with the above described method.
- the nickel deposits obtained in the manner described above have, moreover, the advantage of not requiring laborious treatments, polishings, etc., when it is desired to cover them with a bright chromium layer.
- the coloring (burnishing) of the nickel layer is not eve necessary and the chromium plating can take place immediately.
- articles of aluminumor aluminum alloys can receive a bright deposit'of electrolytic nickel having a strength and lustre superior to those obtained by the known methods and, in particular, by the electrodeposition of a bright nickel layer on a underlying layer of copper.
- the bright nickel layer is deposited in the presence of brightening agents in accordance with'known techniques (for example, those described in the U. S. Patents Nos.
- the article is to receive a chromium finish, this may be done under the usual conditions, and there is obtained a decorative chromium plating of very high quality.
- the zinc plating of aluminum or its alloys with an alkaline zincate solution in the presence of an alkali cyanide and of a heavy metal capable of forming a cyanide complexi. e. a double cyanide-constitutes according to the present invention, a preparation of the surface to enable the deposition not only of ferrous metals, such as nickel, chromium, cobalt, but also of other metals such as cadmium, silver, gold, tin, etc. and also of alloys, such as bronze, brass, etc.
- the highly adherent brass layer is adapted to serve as a support 7 for other deposits.
- very good results are obtained by depositing on the brass-coated articles, following a simple washing operation, a bright nickel layer by a known process. If a chromium deposit be desired, it may be applied and it has the advantages previously mentioned, resulting from operating in accordance with the present invention.
- Example 1 Articles of Duralumin (that is, an alloy of aluminum containing approximately 4% Cu, 0.6% Mg, 0.6% Mn and 0.4% Si) are degreased first, by means of trichlorethylene and then, electrolytically in a bath containing 100 grams per litre of NaaPOt, gr./l. of NazCOz and 5 gr./l. of NazSiOa at 12 volts, 5 amp./dm. for one minute at 20 C. Following rinsing in running water, neutralization with an aqueous solution containing 15% by volume of H2804, and 5% by weight of H2CrO4, and washing, the articles are immersed for seconds in a solution maintained at 30 C. and containing:
- Example 2 The treatments described in Example 1 are applied to articles made of commercial aluminum, following which the nickel surface is depassivated by dipping the articles for 2 minutes at ordinary temperatures in an aqueous solution containing 300 gr. of H2804 per litre. Once rinsed, these articles are coated with a bright nickel deposit, according to a known process, in a bath composed of 300 gr. NiSOeJHzO, 60 gr. NiClz, 6H2O, 60 gr. H3303, 1000 gr. of distilled water and 10 gr. of brightening agents (described in U. S. Patent No. 2,191,813); this bright nickel plating is carried out at 55 C. with a current density of 4 amp./dm. for 10 minutes, while the articles are agitated mechanically.
- a bright nickel deposit according to a known process, in a bath composed of 300 gr. NiSOeJHzO, 60 gr. NiClz, 6H2O, 60 gr. H3303, 1000 gr. of distilled water and 10 gr. of brightening agents (de
- Example 4 Following degreasing and pickling in a bath containing a phosphate and carbonate of soda, articles made of an aluminum alloy containing 4.5% Si, 0.7% lg and 0.5% Mn, are rinsed and neutralized with a solution containing 15% H2804 and 5% H2C1'O4; they are then again washed, and are thereafter dipped for about one minute in 40 Be. nitric acid, to which has been added 0.5% HP.
- Example 6 The operations described in Examples 1 and 3 are carried out on articles of an aluminum alloy containing 11% Mg, thereby producing a final nickel deposit which is bright and highly adherent.
- Example 7 Articles of Duralumin are Zinc plated twice in the alkaline Zincate solution containing cyanides, the operations being carried out as set forth in Example 1; they then receive an electrolytic deposit of brass in a bath having the following composition:
- Example 8 Articles which have been zinc and brass plated, as in Example 7, are directly coated by a known process (Cf. U. S. Patent No. 2,191,813) with a very thick-40 microns-electrolytic deposit of bright nickel. well protected against corrosion by this thickness of nickel, which is very shiny and does not show any blisters or other defects.
- Example 9 Articles which have been zinc, brass and nickel plated, as in Example 8, are chromium plated in a bathmaintained at 35 C.containing 300 gr. HzCrOa and 3 gr. H2504 per litre, with a current density of 12 amps/dink I claim:
