镍质量分数对B30合金耐腐蚀性能的影响
Effect of Ni mass fractionon on the corrosion resistance of B30 alloy
摘要
Abstract
The simulated seawater erosion corrosion experiments were carried out on B30 alloy with different nickel mass fractions.The effects of Ni mass fraction on the microstructures and corrosion resistance of B30 alloy were analyzed by optical microscope,scanning electron microscopy,X-ray diffraction,X-ray photoelectron spectroscopy,and electrochemical impedance spectroscopy.The results show that numerous twins are observed in the of B30 alloy with different Ni mass fraction after annealing.With the increase of nickel mass fraction,the tensile strength and Vickers hardness of B30 alloy increase,the surface corrosion product film becomes denser and the corrosion resistance improves.The corrosion product film of B30 alloy surface is composed of Cu2O and Cu2(OH)3Cl.When the mass fraction of Ni is 33％,the inner corrosion product film on the surface of the B30 alloy has the most positive self-corrosion potential,the smallest self-corrosion current density,the maximum electrochemical impedance of the inner corrosion product film,which is 16 481.28 Ω/cm2,indicating optimal corrosion resistance.关键词
