ATMOSPHERIC CORROSION OF Sn-9Zn EUTECTIC Pb-FREE SOLDER
|
Abstract:
Sn-9Zn alloy is a low cost eutectic Pb-free solder.Since Zn exists in the alloy,the corrosion resistance is poor.Present work was focused on the corrosion behavior of Sn-9Zn in both outdoor atmosphere and an artificial simulated solution.The corrosion product was observed by SEM and analyzed by EDAX.The results showed that in the case of atmosphere corrosion,the surface of the alloy suffered from obvious corrosion after expoure for 12 days only.The morphology of the corrosion product mainly presents as thor...
