Abstract
The invention relates to the alloy activation processes, in particular to processes for activating the tungsten-containing hard alloys surfaces for low-temperature brazing.The process, according to the first variant, includes the electrochemical activation of the alloy surface with an electrolyte, containing, g/l:at an electric current density of 1…100 A/dm2 and the temperature of 20…25°C.The process, according to the second variant, includes the electrochemical thermal activation of the alloy surface with an electrolyte, containing, g/l:at the electrode voltage of 150…220V, the electric current density of 1…2 A/dm2 and the anode temperature of 750°C.The process, according to the third variant, includes the electrochemical thermal activation of the alloy surface with an electrolyte, containing, g/l:at the electrode voltage of 150…220V, the electric current density of 1…2 A/dm2 and the anode temperature of 750°C.
