BEHAVIOR OF WORK HARDENED SnPb-SOLDER AFFECTED COPPER ON CORROSION RESISTANCE IN pH VARIED ENVIRONMENTS

Copper based materials are widely used in industrial and marine applications due to good mechanical properties and high corrosion resistant behavior. But the corrosion immunity varies for the variation of environmental factors. Moreover, alloying elements can have role on corrosion behavior, especia...
