摘要
为探讨油套管钢的选材问题,采用正交试验设计,在高压釜中对五种典型材料进行了CO2腐蚀失重试验,用扫描电镜对试样进行了形貌观察。得出了几种材料在CO2环境中的耐蚀顺序:18-8>1Cr13>10g Al>N80 Zn>N80。对试验结果进行了分析讨论。
Five kinds of typical materials were tested in autoclave purged with CO2 atmosphere. The surface morphology and composition were observed and anolyzed. Through orthogonal test, corrosion rates were obtained with weight-loss test. The corrosion resistance of materials was in the order of 1Cr18Ni9Ti〉1Cr13〉aluminized mild steel〉zine impregnated N80〉N80.
