The speed of the absorption of nitrogen and its elimination of liquid alloy decreases appreciably in the presence of low contents of active substances. In our work studies on the influence of certain factors are presented on the kinetics of the elimination of hydrogen starting from copper and its alloys. For the study one chose pure copper, copper with the additions of phosphorus 0.01 and 0. 04%, of tin 10% and nickel 10%, i.e. with components, having various surface activities. ER -
