Abstract

Time-dependent experiments were carried out to study the corrosion behavior of AISI 304 austenitic stainless steel before and after low-temperature oxy-nitriding in HCl solution. The weight loss of the untreated sample was higher than that of the nitrided sample after HCl corrosion. When immersed for a short time, the nitrided sample remained relatively intact, while when immersed for a long time, the nitrogen-rich layer was damaged. XPS analysis showed that the passive film of the low-temperature oxy-nitrided sample was complete. The structure of passive film on the LTON sample was characterized by Mott–Schottky test, and the effect of nitrogen on the corrosion resistance of the material was discussed. The wear test results show that the oxy-nitrided samples after HCl immersion corrosion still maintained high wear resistance.

AISI 304奥氏体不锈钢的低温氧渗氮，以抵抗HCl介质中的腐蚀和磨损

抽象的

进行了与时间有关的实验，以研究AISI 304奥氏体不锈钢在HCl溶液中进行低温氧氮化前后的腐蚀行为。HCl腐蚀后，未处理样品的重量损失高于氮化样品的重量损失。当短时间浸泡时，氮化的样品保持相对完整，而当长时间浸泡时，富氮层被破坏。XPS分析表明，低温氧氮化样品的钝化膜完整。通过Mott–Schottky试验表征了LTON样品上的钝化膜结构，并讨论了氮对材料耐蚀性的影响。磨损测试结果表明，在HCl浸入腐蚀后，氧氮化样品仍保持较高的耐磨性。
