摘　　要：采用失重分析、腐蚀形貌观察等试验方法,研究了原位自生TiCp/Fe、VCp/Fe复合材料在酸环境下的耐腐蚀性。结果表明,在常温(25℃)或较高温度(85℃)的0.1%硫酸溶液腐蚀介质中,TiCp/Fe、VCp/Fe复合材料都比45钢和HT250具有更好的耐腐蚀性能,其中VCp/Fe复合材料更为优越。Corrosion resistances of In-situ TiCp/Fe and VCp/Fe Composites in acid environment were tested by means of weight-loss analysis and SEM of corrosive surface. The results of corrosion resistance test showed that, in the static immersed corrosion conditions of 0. 1% H2SO4 water solution with the temperatures of 25℃ and 85 ℃, the corrosion resistance of VCp/Fe composite performed better than TiOp/Fe composite. And, both of above properties VCp/Fe and TiOp/Fe composites were obviously superior to those of 45 steel and HT250.
