ACID-RESISTING ARTICLE AND METHOD OF MAKING; SAME.
Application filed July 26,
; To all whom it may 0001' Gem Be it known that I, ALVAH CLEMENT, a citizen ofv the United States, residing at- Cleveland,,in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Im arovement in Acid-Resisting Articles and ethods of Making Samefof which the following is a full, clear, and
exact description.
This invention has to do with a method by which a metal alloy fabricated into suitable forms, may be prepared'so as to ef-,
fectivelyresist the action of sulfuric acid in all its forms, particularly hot dilute sulfuric acidpm A Experience reveals the fact that an alloy of iron and chromium in which alloy-carbon is present, as carbids of iron and chromium, is in certain proportlons highly reslst-ant to the actlon of sulfuric acid in 1ts various forms.
However, the, resence of any considerable iron and chromium in the alloy renders the metallic alloyhard to fabricate and difiicult to machine. Furthermore, such an alloy tends toward brittleness, which, of course, is objectionable particularly where the alloy is made up intopumps, pipes and cocks and similar articles which enter into the making of a piping system through which the sulfuric acid may be caused to flow.
This invention therefore proposes a method for obtaining in the ultimate article the presence of iron and chromium carbid at those parts or surfaces of the article which encounter the acid, and which therefore should exhibit the properties of resistance to the acid.
In proceeding with this method I form an alloy of iron and chromium of the desired proportions which generally may be sisting.
Specification of Letters Patent. Patented A 26 1 921:
1917. 'Serial No. 182,913.
be directly quenched in oil, water or other sultable quenching medium, or otherwise quickly cooled, which induces in the body at the surface thus treated, an impregnation or coating which contains a highamount of carbon in the form of carbids of iron an chromium. y
The surfade thus treated will, therefore,
be "ery highly resistant to sulfuric or hydrochloric acid in concentrated or dilute form,
and whether the acid is in hot or cooled condition.
The entire body of the article itself need not necessarily be impregnated with carbon, as the only necessary thing, is to treat the surface which is to be exposed. However, it will, of course, be apparent that if the body of, the article itself absorbs more or less carbon during the heat treating process it will not be objectionable, so long as the surface which will be contacted by the acid,
is made sufiiciently resistant by the method before disclosed.
Having claim isf 1. The method iron chromium alloy to have an acid resisting surface which consists in making an iron chromium alloy of the desired proportions which alloy is substantially carbonless, then fabricating the alloy into the article it is desired to make, treating the said article in suitable fashion to impregnate the surface, which should be acid resisting, with carbon, and quickly cooling the surface which is to be acid resisting in any suitable manner, thereby to induce the formation of iron and chromium ca-rbid in the body of thearticle at the surfacegvhich is to be acid re- 2. As aILfiItIClG Of manufacture having describedmy invention, what of forming articles of an aILacid' resisting surface, said article comprising a body portion of analloy of desired ingredients, someor' all of which are I capable of forming car'bids'whichare acid resisting, the said article at substantially onlythe surface which is to be acid resisting containing a large proportion of carbids of the metals making up the alloy.
3. As an article of manufacture having an acid resisting surface which consists of a body formed of an alloy of metals of desired ingredients, some or all of which are capable of forming carbids which are acid resisting, that portion of the article which ity to, be exposed to contact with the acid I being made resistant by the presence of carbids of the metals forming the alloy assubstantially only the surfaceexposed. 4:. As an article of manufacture having an acidresisting surface, a body composed of an alloy 'of iron and chromium, the acid remy signature. I
