Abstract
Nickel solubility in ternary Ni-Cu-Mn alloys (20 Ni-40 Cu-40 Mn, 30 Ni-30 Cu-40 Mn, 30 Ni-40 Cu-30 Mn, 40 Ni-30 Cu-30 Mn and 50 Ni-30 Cu-20 Mn) was investigated in 1% lactic acid (pH=2.3) and 0.1% sodium sulphide solution (pH=12.0). The tarnish test in 0.1% sodium sulphide solution showed that all ternary Ni-Cu-Mn alloys have very small amounts of nickel released from them. It also appears that the ternary 40 Ni-30 Cu-30 Mn and 50 Ni-30 Cu-20 Mn alloys have a lower nickel solubility than those of the other alloys in 1% lactic acid.
