铜片在纳米碳化硼水基流体中的腐蚀行为

Corrosion Behavior of Copper in Nano Boron Carbide Water-based Fluids

纳米流体已经被广泛地研究用于提高系统的传热性能和效率,然而对纳米流体的防腐蚀性能关注较少,因此本实验研究了铜片在纳米碳化硼(B4C)流体中的耐腐蚀性能。通过模拟加速防蚀实验,在不同分散情况下的纳米碳化硼流体中对铜片的腐蚀程度进行对比。实验结果表明:采用非离子分散剂,分散介质为膜处理水,流体呈中性或碱性且温度较低时,水基纳米碳化硼流体具有良好的抗腐蚀性能。

Nanofluids have been studied extensively for improving heat transfer performance and efficiency. However, study for nanofluids corrosion concerns less, therefore, the copper corrosion resistance in nano boron car- bide fluid was studied. By simulating accelerated corrosion test, comparing the extent of corrosion of copper in nano boron carbide fluid under different dispersion conditions, the experimental results show that： using non-ionic dispersa- nts, the dispersion medium is membrane-treated water, neutral or alkaline fluid and in lower temperatures, water- based nano B4 C fluid has good corrosion resistance.
