With amorphous electrodeposition of nickel - tungsten tunic of minute crystalloid

摘要

(57) Abstract With electrodeposition method, per 1l approximately the nickel of 0.034 - approximately 0.047 mols, per 1l approximately the tungsten of 0.15 - approximately 0.28 mols, per 1l approximately per hydroxy carboxylic acid, and 1l of 0.13 - approximately 0.43 mols 0 mols or from the electrodeposition bath which approximately includes the boron of 0.077 - approximately 0.15 mols in melting state nickel - tungsten content tunic is formed on the base substance. PH of electrodeposition bath is approximately 6 - approximately 9, electrodeposition desirably is done at the temperature of approximately 100F - approximately 140F.
