Abstract

In a method of depositing on Al a layer of a metal which can be readily soldered, oxide is removed from the Al surface, the surface is heated and a layer of Cu, Cu alloy, Zn or Sn is sprayed thereon. Oxide may be removed by rubbing with emery and heating may be effected at 350 DEG -450 DEG C. in air. Suitable copper alloys for spraying contain 2-8% of either Ti or P. In the case of a Cu layer, soldering is preferably further facilitated by supersonically tin-plating the layer. The example relates to soldering a cover on to an electrical condenser casing.
