Efecto de la microestructura y la concentración del ácido en la corrosión de aleaciones binarias Pb-Sn por Borrego Navejas, Rocío

“…The present work is aimed to study the behavior of Pb-Sn alloys treated under defined conditions of temperature and time as thermal treatments for the study of microstructure and corrosion effects. Once different thermal treatments were applied, its mechanical properties, micro-hardness, microstructure and corrosion rate were evaluated to determine which conditions generate the best performance. …”
