1 UNITEDSTATES PATENT OFFICE WILLIAM It. CH'AIIN, OF INDIANAPOLIS, INDIANA METAL CEMENT Priming. Application filed January 4, 1930. Serial No. 418,660.
1 This invention relates to cementing comthen removed from the pressure and pounds to be used particularly in joining quenched. If desired the temper may he Qmetals. drawn afterwards to suit the work.
An object of the invention is to provide a It will be obvious to those skilled in the cement which will secure perfect union beart that various changes may be made in my v tween the joined metals but which will form product without departing from the spirit a union less noticeable than is true with of the invention, and I therefore do not limit \known cements. While in its use it is not myself to those proportions named in the to be limited to any partcular metal neverspecification, but only as set forth in the apfijtheless it has been found highly satisfactory pended claims.
as a cement for cementing tungsten carbide Having thus fully described my said inand high speed steel to a steel back or other vention, what I claim as new and desire to base. secure by Letters Patent, is: 1 1 For the purposes of this compound I prefl. A cementing compound consisting of embly use a mixture of silico manganese, fine approximately silico manganese, be- 65 steel filings and powdered borax glass. In tween 1% and 10% powdered borax glass, 1 the preparation of the product these elements and the remainder fine steel filings, substanare reduced to a fine powder and then tially as set forth. 7 thoroughly mixed to insureastrictly uniform 2. A cementing compound consisting of fieompound throughout. While not wishing approximately 65% silico manganese, 25%
-toberestricted to any strict proportion of the fine steel filings, and 10% powdered borax elements mentioned I have found the followglass, substantially as set forth ing proportions result in a highly satisfae- In witness whereof, I have hereunto set product, namely, 65% silico manganese, my hand at Indianapolis, Indiana, this 2nd 11 1 25% fine steel filings and 10% powdered day of January, A. D. nineteen hundred and ,1 borax glass. These proportions have sethirty.
Retired particularly good results in use with WILLIAM R CHAPIN tungsten carbide, high speed steel, stellite and other metals. 1 In the use of my cement the parts to be so t 1 cemented are placed together and are covered p L with approximately 5'; .of an inch of the 451% cement. The parts are then heated to a temture suite to the particular elements to M joined, for example, in cementing high speed steel the cementing temperature will be in the neighborhood of from 2300 to 2350 F. For stellite the temperature may be approximately 2200 to 2250 F. For 49 tungsten carbide the cementing temperature A ranges between 217 5 to 2250 F. During 1 1 the eating the parts are held together. Af- 1 ter removin from the furnace the joints are H pressed tig tly together and any surplus 1 00m ound is removed.
I en large pieces are to be cemented they are first preheated to a temperature in the neighborhood of 1500 to 1600 F. They M are then allowed to cool under pressure until such time as the cement has set in the joint, W1
