Abstract Taking into account the dynamic behaviour of the passive layer formed on lead and lead-tin alloys, this work emphasises the effect of the polarisation potential and the polarisation time on the electronic conductivity of the passivation layer. When the lead electrode was polarised in the passivity region (700 mV versus Hg/Hg 2 SSO 4 electrode), the polarisation resistance increased but decreased when tin was alloyed. This behaviour is interpreted by the increasing formation of semi… CONTINUE READING
