The temperature gradient is the main driving force for the corrosion of materials in molten fluorides in molten salt nuclear reactors (MSR). In this paper, the corrosion behavior of Fe and 316L stainless steel in molten (Li,Na,K)F with temperature gradients of 650/700 ^oC and 600/700 ^oC is investigated. The experimental results indicate that the potential difference of materials in molten fluorides with a temperature gradient is the main driving force for corrosion. The larger the temperature gradient, the more serious the corrosion of the material will be, especially for samples at the hotter end of the range.

316L不锈钢在温度梯度下的熔融氟化物中的电化学腐蚀行为。

温度梯度是熔融盐核反应堆（MSR）中氟化物中材料腐蚀的主要驱动力。本文研究了Fe和316L不锈钢在温度梯度为650/700 ^o C和600/700 ^o C的熔融（Li，Na，K）F中的腐蚀行为。实验结果表明，温度梯度下熔融氟化物中材料的电势差是腐蚀的主要驱动力。温度梯度越大，材料的腐蚀越严重，特别是对于温度范围较高的样品。
