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.
