ELECTRIC DEPOSITTING OF CHROMIUM FROM ELECTROLYTES CONTAINING ORGANIC BRIGHTENERS

There the purpose is to develop the electrolytes with the use of organic agents for the raising of chromizing rate and for the rise of quality of chrome platings to be made. The electrochemical methods of study (among them are the potentiostatic and electroplating-static methods, the polarography, the chronopotentiometry), the chromatomass-spectrometry, the roentgenography, the metallography have been applied. The electrolytes of chromizing with the brighteners of organic compounds have been developed for the first time. The products of interaction of chromic acid with the organic agents have been ascertained; the distinctions of electrochemical process have been explored. The formation of amorphous electrodeposit of chromium and the conditions of its making have been ascertained for the first time. The chromizing electrolytes, which compare favourably with the electrolytes in use in the industry today in the rate of plating depositing and in the diffusing power, have been put into operation. The electrolytes and the process of electrolytic chromizing have been introduced. The rate of plating depositting has been risen 1,5 - 4 timesAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
