WILLIAM GEORGE CLARK, OF LONDON, ENGLAND.
PROCESS FOR COATING METAL ARTICLES WITH OTHER MINERALS.
No Drawing.
To all whom it may concern:
Be it known that I, WILLIAM GEORGE CLARK, subject of the King of Great Britain, residing at No. 36 New Broad street, London, England, have invented a new and use ful Process for Coating Metal Articles with other Minerals, of which the following is a specification.
This invention relates to improvements in the process whereby copper, or an alloy thereof, is caused to form a coating to the surface of iron and steel plates or other articles composed of such a metal which will be referred to hereafter as iron this metal constituting the aramount ingredient.
The purpose of this invention is to render the copper or alloy coating absolutely continuous and indivisible from the iron under such mechanical treatment as may tend to separate the layer in an intact condition.
The advantages to be derived from the invention are the perfect protection of the iron from corrosion by the absolute continuity and the complete adherence of the coating and the provision of means whereby two adjacent plates of iron may be united throughout their entire area of contact without requiring them to be subjected to a temperature in excess of that required to melt the copper or the alloy which constitutes the coatlng.
Iron has been previously coated with copper by immersion in a solution of copper salt, with and without electrolytic action, after the chemical cleansing of the surface of the iron, and attempts have been made to more thoroughly secure the deposited film of copper to the iron by heating the coated article to the temperature of melting copper. This process has been only partially successful because the heating has taken place under circumstances which would permit of some of the copper becoming oxidized.
According to the present invention the coating of copper or alloy thereof is, during the heating operation, rotected from oxidation by being covered by a molten nonoxidizing substance composed for example of one or more of the fiuxcs borax, boracic acid and carbonate of soda and preferably of a mixture of the three, this substance be ing capable of being maintained at the temperature at which copper will melt without serious loss by volatilization or other deterioration and having at that temperature Specification of Letters Patent.
Application filed October 27, 1911.

Serial No. 657,076.
such a viscosity as to enable it to adhere to the heated surface. point of the metal of the coating, is transmitted thereto through the medium of the molten flux by which it is covered whereby every portion of the surface is equally protected and heated. ()n removal of the coated iron a film of the flux will adhere thereto and provide a subsequent protection until removed by abrasion, rolling, washing or otherwise.
By the present invention the adherence of copper to thin plates or other articles of ironcan be rendered as perfect as the adherence of tin or zinc to such iron articles by the process of immersion of the iron articles into the molten metal. On account of the relatively much higher temperature of fusion of copper the corresponding operation of immersion of thin iron into molten copper so deteriorates or destroys the iron foundation as to render the process impracticable. By limitin the quantity of molten copper which is welded on to thin iron articles by the process of the present invention the evil effects which would be due to immersionin molten copper are avoided. In the case of thin iron plates or other iron articles which are not plates, the articles are caused to receive the coating of copper or alloy thereof by immersion in a solution of a salt of the metal and the coating is subsequently welded on to the iron foundation by immersion in the previously described molten flux which is subjected to a temperature approximately that at which copper or the alloy which constitutes the coating will melt. On removal from the bath of flux, the adherent film will protect the sur face from oxidation until cooled and thereafter if not mechanically removed. If it is desired to weld to a thick plate of iron a coating of copper or other alloy on one face thereof, the plate with the coated surface upward may be covered with the flux and the temperature raised to the meltin r point of the coating metal, and an additiona quantity of the coating metal may be added in the molten or solid condition to produce a. thicker coating. When it is desired to unite two iron plates each of which has been coated with copper or an alloy thereof. as above described, the plates are superposed with the coated surfaces facing each other and the films of congealed flux interposed to which Heat, up to the melting additional flux may be added. After rais- 1 ing the temperature of the compound plate to that of the melting point of the coating of copper or alloy thereof, the compound plate is subjected to pressure to squeeze out the interposed liquid flux as for example by passing the two plates between rollers pressed forcibly together and the two plates will be perfectly unit-ed throughout their entire area of mutual contact.
I claim:
1. A process for coating iron articles with another metal and adherently securing said coating thereto, consisting in immersing the iron article in a solution of a salt of said other metal and heating said thereby coated iron article in molten non-oxidizing flux to the fusion temperature of said other metal.
2. A process for coating iron articles with copper and adherently securing said coating thereto, consisting in immersing the iron article in a solution of a copper salt and heating said thereby coated iron article inmolten non-oxidizing flux to the fusion temperature of copper.
' In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
WILLIAM GEORGE CLARK.
