Description
Patented June 1931 UNITED STATES PATENT OFFICE OBIN A. BASSETT, OI OKLAHOMA CITY, OKLAHOMA, ASSIG NOB TO THE NATIONAL IN- DUSTRIAL LABORATORIES CORPORATION, OF
POBATION OF DELAWARE OKLAHOMA CITY, OKLAHOMA, A COB- PROCESS FOR TREATING METALLIC ARTICLES No Drawing. IApplication filed November After iron or steel has been coated with a metal of lower melting point, it has heretofore been impossible to heat-treat the iron or steel without destroying the coating. Tin or zinc coating on iron or steel has thus been narrowly confined to such articlesas could be coated as a final step and so leave the coating undisturbed. Correspondingly the advantage of a cheap anti-rust coating for steel has been verysharply limited.
In accordance with my invention, metals after being coated with other metals which are inherently fugitive by-reason of relatively low melting point or ready'oxidizability may be heat-treated variously as desired without in any way damaging the coating. In some conditions, the character of the coating may in fact be improved. Y
To the accomplishment of the foregoing and related ends, theinvention, then, consists of the features hereinafter fully described, and particularly pointed out in the claims, the following'description setting forth but a few of the various ways in which the principle of the invention may be used.
In applying my process, I may proceed for example as follows :the article to be treated, for instance steel, is coated with a relatively low melting metal such as zinc, by hot or by cold galvanizing, and is then coated or covered by about to inch thick (depending upon the size of the article) with what for want of abetter name (and without committing myself to. any theory of action) I may call a fixative agent, and which comprises preferably a composition of potassium cyanide or sodium cyanide about 30 per cent, borax about 20 per cent, sodaash or sodium carbonate about 20 per cent., powdered carbon preferably graphite about 20 per cent. This may be applied dry where convenient by warming the steel article and plunging it into the powder so that enough will adhere,
or the material may be made up with an adhesive binder such as glue water or the like and be spread on by a brush,.trowel or other con; venient means. The steel article is now heated up to the temperature necessary, and is quenched by water, oil or other means forthe tempering desired, and on cleaning, the

zinc coating will not only be'found intact, but capable of taking on a superior polish. Instead of tempering, the steeLarticle can be-annea-led, or the heating can be employed for the purpose of bending or shaping the article. The feature in any case being the possibility of, subjecting the metal-coated article to high temperatures for desired heattreating or. shaping, temperatures which would normallylbe destructive to the metal coating, but w ich in accordance with my process are successfully borne. In this-mane ner tools, implements, cutlery, etc. can be galvanized or tinned and afterwards tem pered. I can in fact make needles of tinned or galvanized iron wire and temper them to any desired hardness.
The process is not confined to steel or to articles coated with zinc but metal articles generally, coated with tin,- copper, brass, lead, etc. may be similarly successfully heat-treat ed without destroying the metal-coating Thus, not only steel but other iron-base articles canbe treated, for instance iron wire may be galvanized and then treated in accordance with this process, the wire being coated with the fixative agent and thensubjected to a cherry-red heat for a few minutes In this manner wire and cables can be readily provided which will have the desired tensile strength, hardness and'malleability and be thoroughly rust-resisting for fencing, suspension bridge work, rigging, etc.
I may also take tinned or galvanized sheet iron barrels or barrel stock and coat withthe fixative and heat, and thus secure improved rust-resisting and wearing barrels, cans, etc. By coating thin iron plates with the fixa tive and heating, then welding a number of the plates together, placing galvanized plates on the outside, superior built-up plate metal for, safes -armor plate, etc. may be produced.
Other modes of applying the principle of my invention may be employed instead of the one explained, changes being made as regards themethod and means herein disclosed, provided the step or steps or means stated by any of the following claims or the equivalent of such stated step or steps or means be em ployed.
I therefore particularly pomt out and distinctlX claim as my invention process of treating metal coated with i a more fugitive metal, which comprises heating the coated metal in the presence of a fixative agent including the element carbon.
2. A process of treating metal coated with a more fugitive metal, which comprises heating the coated metal in the presence of a fixative agent including a cyanide.
3. A process of the character described, which comprises applying a fixative agent including the element carbon to an iron-base article coated with a fugitive metal, and then heating.
4:. A process of the character described, which comprises a plying a cyanide and free carbon to an ironase article coated with a fugitive metal, and heating.
'5. A process of the character described, which comprises heating in the presence of a cyanide and gra hite an iron-base article coated with a fugitive metal.
6. A process of treating metal coated with a more fugitive metal, which'comprises applying a cyanide to the coated metal, and then heating.
7. A process of treating me'tal coated with a more fugitive metal, which comprises aplying a fixative agent including a cyanide,
orax, sodiumcarbonate and carbon, to the coated metal, and then heating.
8. A process of treating metal coated with a more fugitive metal, which comprises a giying a fixative agent including a cyam' e,
rax, sodium carbonate and graphite, to the -coatedmetal, and then heating. 9. A process of treating an iron-base arti-- cle coated with a fugitive metal, which comprises applying a fixative agent including a I cyanide, borax, sodium carbonate and graphite, the coated metal, heating, and temper- 1n Y e 19signed by me .this 2nd day of November,
