摘要

摘要: 向鎳基耐蝕合金中添加Ti、Fe元素,采用手工電弧爐熔煉制備新型Ni-Cr-Mo-Cu-Mx耐蝕合金,用化學浸泡法、電化學法(極化曲線法、循環伏安法)對其耐晶間腐蝕和耐點蝕能力進行研究.結果表明:在Ni-Cr-Mo-Cu合金中加入Ti元素可以增強其耐晶間腐蝕能力,減弱其耐點蝕的能力;加入Fe元素會降低Ni-Cr-Mo-Cu合金耐晶間腐蝕的能力,但提高該合金耐點蝕的能力;實驗合金晶間腐蝕與點蝕的電化學行為和特征與其浸泡腐蝕的結果是吻合的.

Abstract: Ni-Cr-Mo-Cu-Mx nickel-base corrosion-resistant alloys were prepared by adding Ti and Fe with a manual electro-arc furnace.Intergranular corrosion and pitting corrosion resistances of these alloys were investigated by chemical erosion and electrochemical corrosion techniques(polarization curve methods and cyclic voltammetry).The results showed that the intergranular corrosion resistance of the alloys added Ti increased and the pitting corrosion resistance decreased.Fe addition deteriorated the intergranular corrosion resistance of Ni-Cr-Mo-Cu alloys but improved the pitting corrosion resistance.The electrochemical behaviors and characteristics of intergranular corrosion and pitting corrosion coincided with the results of chemical erosion.
