摘　　要：依据百分因子(APF)法,参考现今先进耐蚀合金,预设计了6种APF介于2.5～3.3的通用性镍基耐蚀合金成分.应用真空感应炉和手工电弧炉熔炼合金获得了良好的效果.在氧化性酸和还原性酸进行化学腐蚀,与1Cr18Ni9Ti的耐蚀性能对比.研究结果表明,设计合金具有优异的耐蚀性及良好的通用性,并对设计合金进行了评价;合金在固溶处理后耐蚀性能有所提高;随着APF的增大合金的抗氧化性介质的耐蚀性能提高,抗还原性介质的耐蚀性能降低.Based on the APF method and advanced corrosion resistant alloys available now, six schemes （APF from 2. 5 to 3. 3）were designed for versatile Ni-base corrosion resistant alloys, which were prepared by using vacuum induction melting and manual electro-arc furnace, with a good result. Alloys designed and 1Cr18Ni9Ti are dipped into the reducing and oxidizing acid medium, and their corrosion resistance was compared. Experimental results show that alloys （APF from 2. 5 to 3. 3） have excellent corrosion resistance and catholicity. After solid-solution treatment, the corrosion resistance is improved. As APF increases, the corrosion resistance in oxidizing medium is improved and that in the reducing medium is decreased.
