在试验室里对一些商品含Cr钢(Cr含量从2.25—25％)进行高温冲蚀腐蚀试验表明,材料的冲蚀腐蚀阻力强烈地依赖于它的抗腐蚀能力.合金的冲蚀腐蚀阻力随着它们的Cr含量的提高而提高.当Cr含量达～9％时,材料的耐冲蚀腐蚀阻力有个飞跃.冲蚀粒子的本质和形状对冲蚀腐蚀阻力也有很大影响.最后,对材料的蜕变机理进行了探讨.
Combined corrosion-erosion (C-E) behavior of some commercial steelscontaining 2.25--25 wt-%Cr have been investigated at 850℃ using air as carryinggas and 130μm dia. SiC or Al_2O_3 as erodents. It was found that C-E behaviorstrongly depends on the corrosion resistance of steels. The C-E resistance increaseswith increasing Cr content, and a drastic raise of the resistance occurs at about9 wt-%Cr. Obvious influences of the nature and shape of the particles on the C-Erate of steels was noticed. Mechanisms of material degradation have also beendiscussed.
