Description

United States Patent Ofifice 2,849,337 METAL COATING BATHS John W. Robinson, Brecksville, Ohio, assignor to the United States of America as represented by the United States Atomic Energy Commission No Drawing. Application November 28, 1945 Serial No. 631,482
1 Claim. (Cl. 117-114) processes.
In the application of bronze coatings to uranium by dipping the uranium object to be coated into a molten without a flux coating baths of high copper content tend to lose their ability to wet uranium.
An object of the bronze coating baths In accordance with the present invention a bronze bath, which consists predominantly of copper and which has separated as scum from the bath.
The process is particularly applicable to dry bronze baths of high copper content since baths containing less 2,849,337 Patented Aug. 26, 1958 than about copper do not become subject to the difficulty encountered with the high-copper baths and the use of flux on bronze baths of high copper content also seems to avoid the difliculty.
Example A bronze bath containing 67% by weight copper and 33% by weight tin had been used for some time for the coating of metallic uranium objects. uranium rod was dipped in the bath for 1 /2 minutes while the bath temperature was 830-840 C. Upon responding to to the bath and by skimming. in the bath for 1% minutes While the bath temperature was between 830 and 840 C. and upon withdrawal was same bath at a temperature between 810 and 790 C. for .45 seconds and upon removal was found to be substantially uniformly coated with the bronze coating metal.
corresponding to 4 of the weight of the bath.
