Specification of Letters Patent.
Patented Jan. 12, 1909.
Application filed March a, 1908. Serial N 0. 419,170.
To all whom it may concern: 1
Be it known that I, CARL H. ZIEME, a citizen of the United States, residing at New Castle, in the county of Lawrence and State of Pennsylvania, have invented a certain new and useful Process of Coating with Metals, of which the following is a specification.
My invention relates to coating metallic objects or materials, such for instance, as iron and steel with a metal or combination of metals of a character suitable to resist external influences.
In an application filed November 4, 1907, (Serial No. 400,456), in the name of George L. Patterson, Thomas L. Mornes and myself, a process is described, for galvanizing, which consists in applying to the surface to be coated, a liqui slip, the mixture containing partially oxidized zinc in finely divided form and then inclosing the metal thus coated, in a suitable receptacle in which it can be sub jected to heat at between 600. and 1000 Fahrenheit; this process causing the zinc to form upon the metal a closely adhesive and substantially amalgamated coating of very high character, resembling a coating formed by electrolysis, but more firmly bound to the underlying metal.
In U. S. .Letters Patent No. 701,298, granted June 3, 1902, to Cowper-Coles, is described a process of coating metals by heating the metal to be coated to a temperature corresponding to the dull red heat of iron in the presence of pulverulent zinc partially oxidized, said patent also alluding to the a plicationof zinc alloy in place of the zinc a one, it being explained that when metallic coating material is used, a certain proportion of oxid must be present and that this is effected by adding oxid of zinc or submitting the metallic zinc to oxidizing influences.
According to my present invention, I deposit two or more metals simultaneously upon a metallic surface to be coated, by making a slip or coating containing oxids of said metals mechanically mixed with a suitable vehicle preferably consisting of an inert substance and a fluid, and I then subject the me tallic body thus coated to the action of heat at from 600 to l000 Fahrenheit, and there- "by reduce the coating to the several metals which have united with the metallic surface in their metallic state and a residuum con- .so as to form a coating thereon.
sisting mainly of the inert element of the vehicle which can be readily brushed away.
For an illustrative process, though I desire it to be understood that my invention is not limited to specific proportions or other details, I take a metallic body to be surfacedfor instance, a sheet of iron or steeland I clean the same, as for instance by a pickling bath. I prepare a slip or bath consisting of 90% of the metallic oxid element and 10% of an inert substance such for instance as finely divided clay suitable to mix with the metallic element and keep it in suspension, together with enough Water to make a pasty bath. The metallic oxid element consists of mechanically fixed oxids of the several metals that it .is desired to simultaneously deposit upon the metal, for instance, the oxid of zinc together with the oxid of tin (stanni'c oxid) and the oxid of lead (litharge or minium) and the oxid of any other suitable surfacing or alloying metal, these being in the proportions of 95% of zinc (zinc dust) and 5% of either of the metallic oxids or any combination thereof. I then dip the metallic sheet or other object in the slip, if both sides are to be coated, or otherwise bring into contact with the slip that portion of the metallic article that is to be surfaced, I then take the article and either after or before drying the coating, I subject it to the action of heat at between 600 and 1000 Fahrenheit, preferably under conditions which exclude free alr. allowed to cool, when it will be found that the several metals will have been deposited in metallic state, making an evenly distributed homogeneous and amorphous surface which is firmly bound to the underlying metal throughout a in a manner to permit working the metal without separation of the surface deposited.
My process is obviously quite different from one in which a previously prepared alloy of metals is em loyed and applied in the presence of a meta lic oxid or of oxidizing influences,- for the reason that each metal to be deposited is partially oxidized in advance to the de ree suitable to insure its proper action in t' e process; moreover, it is by no means certain that the oXid of one metal is suitable for depositing a different metal.
I do not limit myself to the preparation of After the heating step, the object is following is what I claim as new therein mixture of the metallic substance inthe proa sli by the use of an inert substance. Some 1 oxi s may be found to be suitable for a plication Without the use of an inpalpable inert substance to hold the oxid in suspension.
- Having thus described my invention, the
1. The process of surfacing a metal with a plurality of other metals, one of which is zinc, which consists in providing a mixture of the metals to be de osited, of which the zinc is in partially oxi ized form and the remainder in the form of oxid, then applyin the mixture to the metal to be surfaced an then heating the whole to a degree suflicient to deposit the surfacing metals in metallic state.
2. The process of surfacing metals with a plurality of other metals one of which is zinc, which consists in providing the metals to be deposited in oxidized form in proportions of which the zinc is largely in excess, applying a" portions selected, to the metal to! be suraced, and heating the latter to a suitable temperature to cause the metals to be deposited in metallic state.
3. The process of surfacing a metal with a plurality of other metals one of which is zinc,
which consists in providing a mixture of the l metals in oxidized form' with the oxidized zinc in the proportion of about 95%, applying said mixture to the metal to be surfaced, and then heating the Whole to a temperature sufficient to deposit the surfacing metals in metallic state.
4. The process of surfacing a metal with a plurality of other metals which consists in orming a slip consisting of about 90% of the metals to be deposited, in oxidized form, about 10% of a finely divided inert substance and a suitable liquid, then applying the slip to the metal to be surfaced and subjecting the whole to heat suificient to deposit the surfacing metals in metallic state.
5. The process of surfacing a metal with other metals by heating the same inthe presence of a slip consisting of a suitable iquid, 10% of a finely divided inert substance and 90% of a mixture of the metals to be deposited, made up of about 95% of partially oxidized zinc and about 5% of other metallic oxide.
The" foregoing specification signed at New York, N. Y. this 26 day of Dec., 1907.
