Abstract (en)
[origin: US4652349A] For the production of tin-graphite or respectively tin/lead-graphite layers, it is known to electrodeposit a tin or respectively tin/lead layer and to mechanically incorporate graphite in the boundary zone. In accordance with the method of the invention, the tin-graphite or tin/lead-graphite layer is produced electrolytically in a single operation, operating with an electroplating bath on a strongly acid basis in which graphite powder is dispersed by means of an acid-stable wetting agent, and at temperatures of up to 35 DEG C. In the respective electroplating bath the solution has a pH value equal to or less than 2 and contains in acid-stable wetting agent for graphite.
