本文报道了10CrNiCuP 耐候钢及对比用的 A3钢和进口 Cor-TenA 耐候钢在不同地点的自然环境静态暴露试验和运行车箱顶部动态暴露试验的短期试验结果;同时报道了室内盐雾腐蚀试验、恒温恒湿腐蚀试验及电化学测量的结果,探讨了这几种钢在不同条件下的耐蚀性能。结果表明,10CrNiCuP 钢是一个比较好的耐大气腐蚀新钢种,其耐蚀性能比碳铜 A_3有很大提高,达到了进口耐候钢 Cor-TenA 的水平。
This paper reports the short-term test results of the natural environment static exposure test of 10CrNiCuP weathering steel and the comparative A3 steel and the imported Cor-TenA weathering steel at different locations and the dynamic exposure test of running top of the vehicle box; meanwhile, the indoor salt spray corrosion test, Constant wet corrosion test and electrochemical measurement results to explore the corrosion resistance of these types of steel under different conditions. The results show that 10CrNiCuP steel is a good new atmospheric corrosion-resistant steel, its corrosion resistance than carbon and copper A_3 has greatly improved, reaching the level of imported Cor-TenA weathering steel.
