Abstract
Spreading characteristics of Sn, Pb and nine Sn-Pb alloys on cast iron (3.2% C) have been evaluated by employing zinc ammonium chloride flux (79 parts of zinc chloride and 21 parts of ammonium chloride) at the liquidus temperatures of the solders. The solder, flux and specimen preparation procedures have been reported elsewhere. The solder-flux interfacial tension has been determined by the method of Chalmers and Wadie and contact angles were measured by an optical method. The spreading coefficients have been computed by using contact angle and interfacial tension values.
