Abstract
322,371. Breusing, K., and Gottesmann, U. Dec. 28, 1928. Copper, depositing; treating surfaces; electrolytes, agitating. - Electrodeposits are produced rapidly by using a bath at increased temperature and introducing finely-distributed gases continuously or intermittently. The gas is preferably introduced through clay cells, cane or other porous body and is of such a nature that it can combine with the gas liberated at the cathode. An envelope of felt or other material, which assumes an open texture when immersed, may be provided around the anode to prevent the passage of solid particles. In the production of dies for gramophone records by depositing copper, air or other oxidizing gas is introduced, the bath of copper sulphate may be 23-24‹ BÚ, with 1 per cent of free sulphuric acid, at a temperature of 40‹ C., and the current density may be 40 amps. for a record 30 cms. in diameter. A sufficient deposit will be produced in 4 hours. If desired colloids may be added to the bath.
