摘要

研究310S不锈钢（06Cr25Ni20）在液态锡中的腐蚀行为对下一代聚光太阳能（CSP）系统结构材料的选择具有重要意义。本文研究了饱和和低氧环境对310S不锈钢在700℃液态锡中的腐蚀行为的影响。在这两种环境中，腐蚀随时间的特征是通过微观结构观察进行的。结果表明：饱和氧环境下腐蚀主要以氧化和溶蚀为主，低氧环境下腐蚀主要以溶蚀为主；不同的腐蚀机制导致不同的腐蚀速率，并提出了不同的腐蚀机理模型。形成致密厚实的富cr层，可有效保护母材。

Comparison of corrosion behavior of 310S stainless steel in liquid Sn under saturated and low oxygen environment

The study of the corrosion behavior of 310S stainless steel (06Cr25Ni20) in liquid Sn is of great significance for selecting structural materials for the next-generation Concentrated Solar Power (CSP) systems. This article investigates the effects of saturated and low oxygen environments on the corrosion behavior of 310S stainless steel in liquid Sn at 700 °C. The characterization of corrosion over time in these two environments is conducted through microstructural observations. The results indicate that corrosion under saturated oxygen environment primarily occurs through oxidation and dissolution, while under low oxygen environment, it is predominantly driven by dissolution. Different corrosion mechanisms result in different corrosion rates, and the corrosion mechanism models are proposed. The formation of a dense and thick Cr-rich layer can effectively protect the base metal.
