| 摘 要： | 在Cr、Mo成分一定的情况下,通过改变Cu的质量分数(1%～5%),研究新型Ni-Cr-Mo-Cu高镍耐蚀合金在氧化性介质、还原性介质、氧化-还原性介质和质量分数6%的FeCl3中的耐蚀性能及其在H2SO4、HCl和FeCl3中的电化学行为.实验结果表明,w(Cu)=1%～5%的Ni-Cr-Mo-Cu合金具有优良的耐介质腐蚀、电化学腐蚀性能,在质量分数80%的H2SO4中钝化明显,在质量分数30%的HCl中自腐蚀电流低,在质量分数6%的FeCl3中有钝化区且未发生点蚀.4种实验材料中w(Cu)=3%的合金综合耐蚀性能最好,在质量分数80%的 H2SO4中有更宽的钝化平台和更低的维钝电流.

| Abstract: | Keeping the composition of Cr and Mo constant and changing the mass-fraction of the copper from 1% to 5%,the corrosion resistance of a new Ni-Cr-Mo-Cu high-nickel corrosion-resistant alloys in media such as oxidization,reduction,oxido-reduction,and FeCl3 with mass-fraction of 6% and electrochemical corrosion resistance in sulphonic acid,hydrochloric acid,and ferric chloride were studied. Experimental results showed that Ni-Cr-Mo-Cu alloys with w(Cu) being 1%~5% exhibited excellent performance of media corro... |
