Abstrakt: The experimental data about influence of chemical and electrochemical operations of surface treatment of alloys of molybdenum on adhesion and solderability of electroplatings are provided. Influence of structures and the modes of electrolytes on quality of coverings, adhesion and solderability of the coverings applied on molybdenum alloys is studied. It is proved that use of combination in one electrolyte of two operations: electrochemical etching and at once the carried-out operation of copper plating, leads to increase in adhesion of coverings to molybdenum alloys. It occurs because the oxide layer is rather fully pitted during anodic dissolution, and the most important, it doesn't manage to be formed before deposition again as it occurs in many other known technological processes. The developed technology of galvanic metallization of molybdenic alloys allows: to reduce the number of technological operations, to increase efficiency of process, to use cheaper inventory, to increase adhesion of electroplatings to alloys of molybdenum and to improve their solderability.
