可以看出.无论是Crl5Mo3标样,还是铸态、热处理态高铬铸铁Cr28试样.在腐蚀磨损过程中都具有同样的特点,即磨损刈腐蚀的促进作用很大.均占到腐蚀分量的99以上-这说明在腐蚀磨损的状态下,磨损是促进腐蚀失重的最主要因素。但是它们也存在着不同点。其区别在于静态热强碱浸泡腐蚀状态下,cr15Mo3试样的失重率小于各种状态的高铬铸铁Cr28试样,这表明在静态腐蚀情况下.Cr元素对合金铸铁的耐热强碱腐蚀性能将产生不利的影响。而在各种状态的高铬铸铁Cr28试样中.砂型铸造的铸态试样的静态离蚀失莺率低于热处理态试样,原因在于奥氏体基体的电授电位高于马氏体基体].具有更好的耐热强碱腐蚀性能。但是.从腐蚀分量和腐蚀增量来看,铸态Cr28试样却高于Cr15Mo3试样。低于热处理态Cr28试样,这又表明在动态的腐蚀磨损情况下,较高的Cr含猷对材料的耐磨蚀性能仍然是有益的。这一看似矛盾的结果.证明了高铬铸铁材料在氧化铝矿浆冲蚀磨损下工作时,高的Cr含量对抗强碱腐蚀和抗冲刷磨损两方面的贡献是通过综台作用表现出来的。渣浆泵厂家
