(上接2008年第2期)2镍合金的选择材料的耐腐蚀性能一般是根据实验数据,将材料在介质的各种浓度及各种温度下的预期的耐腐蚀速率汇总在等腐蚀曲线图上。氯化物对材料的点腐蚀以及缝隙腐蚀,是通过测试材料在酸性三氯化铁中的极限点腐蚀温度下,以及极限缝隙腐蚀温度下所产生的点腐 (Continued on the second issue of 2008) 2 nickel alloy selection Corrosion resistance of materials is generally based on experimental data, the material at various concentrations of the medium and the expected corrosion rate at various temperatures in the corrosion curve on. Chloride pitting and crevice corrosion of the material is achieved by testing the point corrosion at the point corrosion temperature of the acid ferric chloride and crevice corrosion temperature
