Description
- neonate. le a To all cut it may concerns."
Be it "a that T, Hangers Aneusrn Rona, a citizen of the Republic of France, and resident of Paris, lErance, have inven anew and useful Process of Producing Metallic e which is y set forth in the following specification.
The premnt invention relates to prove-. ments in rocesses of depting metallic layers or i m upon articles construe of difierent metals. Tn cag out processes of this general class or character, it is com-- men to pass an electric current through a solution of the metal to be deposited, and
it is also coon to employ what is known as the .pulverization treatmt. These proc, however, are not always readily applicable, and it is often preferred tosubstitute therefor, for instance in metalhzmg the interiors of tubes or boxes, the temper. in method. .-Vai-ious ways of. carry ng thismethod into eect have been proposed,
one of which consists in adding to a solution of nickel chlorid, alke chlorids or chloride of a a a or zinc, and
l in utilizing the bath thus obtained in a ho state. According to another process, carbonyl nickel is used. Many other pr are hown, but besides the fact that they do not give a really satisfactory lt from a coercial standpoint, they are not sultable for all metals, particularly for alum, and they are much less satisfactory in forming metallic deposits upon non-metallic articles, such for instance as porcelain.
it is the object of the resent invention to provide a process which shall remedy these defects, and which shall be capable of bringing about the deposition of a good metallic coating both uponany metal, and especially uponalum, and also upon non-metallic. articles or substances.
According to the imfiprov pr, ar
ticles to be coated are rst cleansed in any desired manner, and then subjected to the action of metallic phosphites or hypophosphites, or to the action of alkaline or ammonil phosphites or w a hosphites, or of a salt of the metal to a eposited.
Tn. actually carrying out the invention,
. the clean articles are steeped in a solution such, for instance, as either of the follo which are ven merely by way of peclttton of ltettera )Patent. Pattemtedl meta 5, lmllfia 4 Application at! January re, that. tertal lto. 9100M.
example and which can he more or l varied according as it is desired-to produce the deposit rapidly or slowl Emampl'e I. The hypo sphz'te colation.-Water 1,000 grams, citrate of nickel or other salt of nickel 100 grams, aonia, alkalis or alkaline salts 100 grams, ammoniacal or alkaline hypophosphite 100 grams.
The proportions just given are in no way absolute, as they may be widely varied. The presence of the phosphite or hypophosphite and of the metallic salt is suficient in itself to efl'ect the precipitation of the metal; the metallic salt may be added in proportion, or, on the contrary, the h phophos phite or phosphite may be adde little by little to the said salt. In any case, the articles are left in the bath; until they are sufficiently metallized, after which they are rinsed and dried. The metallic deposit thus obtained may be utilized as a preparatory film or layer, and deposition may there-- boiling, according as deposition is to be ef-j fected slowly orrapidl As a development of the above process, a metal may first .be deposited, and the operation may thereafter be continued by depositing a difierent metal upon the first; thus,
for instance, the articles may first be nick- .eled and then gilded, and thereafter d,
dried and polished.
I claim as my invention- 1. The herein-described process of pro- I ducing metallic deposits, which consists in subjecting the articles to be coated, until suficiently metallized, to the action of a bath containing a solution of a salt of the metal to be deposited and an alkline hypo-' phosphite'. a
2. The herein-described process of PTO. I
ducing metallic deposits, which consists in subjecting the articles to be coated, until sufici'ently metallized, to the action ofL a bath containing 'a solution of a salt of the metal to be deposited, an alkaline hyphophosphite and ammonia. I
3. The herein-described process of pro ducing metallic deposits, which consists in steeping the articles to be treated, until sufficiently metallized, in a, hot bath containing a solution of citrate of nickel, an alkaline hypophosphite and ammonia.
4. The herein-described process of producing metallic deposits upon aluminumsurfaced articles, which consists in subjecting the articles to the action of a bath containing a solution of a salt of the metal to be 'deposited' treated with an alkaline hypophosphite.
5. The herein-described process of producing metallic deposits upon aluminumsurfaced articles, which consists in subjecting the articles to the action of a bath con- FRANQOIS AUGUSTE ROUX.
