Abstract The corrosion behavior of VM12, Sanicro 25, and Inconel 617 in supercritical carbon dioxide at 600 °C and 15 MPa was investigated. Chromia-forming alloys Sanicro 25 and Inconel 617 had better corrosion resistance than VM12, which formed Fe-oxide rich scales on its surface. In all materials, internal carburization zones were found underneath the oxide scales. Based on the results that the growth of corrosion layers of the investigated materials followed a parabolic corrosion law, the stability of the Cr2O3 scale of Sanicro 25 and Inconel 617 was evaluated and the corrosion allowances of the investigated materials were calculated.

VM12、Sanicro 25 和 Inconel 617 在 600 °C 超临界二氧化碳中的腐蚀行为和寿命预测

摘要 研究了 VM12、Sanicro 25 和 Inconel 617 在 600 °C 和 15 MPa 条件下在超临界二氧化碳中的腐蚀行为。铬形成合金 Sanicro 25 和 Inconel 617 比 VM12 具有更好的耐腐蚀性，VM12 在其表面形成富含铁氧化物的氧化皮。在所有材料中，在氧化皮下面都发现了内部渗碳区。根据所研究材料腐蚀层的生长遵循抛物线腐蚀规律的结果，评价了Sanicro 25和Inconel 617 Cr2O3氧化皮的稳定性，计算了所研究材料的腐蚀裕量。
