Abstract The present article investigates the effect of Surface Mechanical Attrition Treatment (SMAT) on the high temperature oxidation of AISI 316L, during isothermal oxidation between 650 and 750 °C in air. The observations show a beneficial effect of the SMAT process on the oxidation resistance of 316L steel, for high temperatures. Indeed, the oxidation kinetics of the treated samples is shown to be related to a preferential growth of chromia starting at 700 °C up to 750 °C. This leads us to conclude that the SMAT used on the 316L reverses the main oxide phase, inhibiting the growth of the hematite and promoting the chromia.

表面机械磨损处理对316L不锈钢氧化行为的影响

摘要 本文研究了表面机械磨损处理 (SMAT) 对 AISI 316L 在 650 至 750 °C 空气中等温氧化过程中高温氧化的影响。观察结果表明，SMAT 工艺对 316L 钢在高温下的抗氧化性具有有益影响。事实上，处理过的样品的氧化动力学显示与氧化铬从 700 °C 开始到 750 °C 的优先生长有关。这使我们得出结论，316L 上使用的 SMAT 逆转了主要的氧化物相，抑制了赤铁矿的生长并促进了氧化铬。
