Literature in the field of dealloying is reviewed. A common example is the dezincification of unstabilized brass, whereby a weakened, porous copper structure is produced. The most susceptible alloys are the ones containing metals with high distance between each other in the galvanic series, e.g. It is also called parting, selective leaching or selective attack. 2 recommended a sample size of 20 percent (with maximum of 25 components) for the one-time inspections for selective leaching conducted prior to the initial LR period. fDezincficatio. The less noble metal is removed from the alloy by a microscopic-scale galvanic corrosion mechanism. Generally, under AL conditions, nickel is more difficult to leach from limonite than from smectite (clay) and saprolite ores [3]. So I will try and send it separately. To combat this, arsenic or tin can be added to brass, or gunmetal can be used instead. The Office of Industrial Technologies (OIT) of the U. S.
