Abstract:
A bath for electrodepositing tin, lead or an alloy thereof, containing a tin and/or lead ion and a sulfate ion becomes stable at pH 1 or higher when a condensed phosphate ion is added thereto. The bath is effective for depositing tin-lead alloy films on sealing glass-metal integrated articles.
Abstract:
Disclosed is a composite plating film for sliding members, essentially containing at least one of the alloy elements selected from tin, indium, antimony, and copper; inorganic particles; and lead; the composition of the composite plating film being:a) at least one of the alloy elements selected from tin, indium, antimony, and copper . . . 2 to 30 weight % in total;b) inorganic particles . . . 0.3 to 25 volume %; andc) lead . . . the balance.
