Experimental results have shown that the Ni-Cr-Mo-Cu alloy with w(Cu)=1%~5% had excellent resistance to intergranular corrosion and pitting corrosion performance, relatively speaking the resistant to intergranular corrosion and pitting corrosion performance of nickel-base alloy with w(Cu)=2% was poor while the nickel-base alloy with w(Cu)=5% had better resistance performance to intergranular corrosion and pitting; and the behavior and characteristics of the test alloy intergranular electrochemical corrosion and pitting corrosion has met exactly with that of their immersion.Read More
