冲蚀
erosion corrosion
ehongsh-冲蚀(erosion corrosion)金属材料表面与腐蚀流体冲刷的联合作用，而引起材料局部的金属腐性。在发生这种腐蚀时，金属离子或腐蚀产物因受高速腐蚀流体冲刷而离开金属材料表面，使新鲜的金属表面与腐蚀流体直接接触，从而加速了腐蚀过程。若流体中悬浮较硬的固体颗粒，则将加速材料的损坏。一般说来，流体的速度愈高，流体中悬浮的固体颗粒愈多、愈硬，冲刷腐蚀速度愈快。腐蚀介质流动速度又取决于流动方式:层流时，由于流体的粘度，在沿管道截面有一种稳态的速度分布;湍流时，破坏了这种稳态速度分布，这不仅加速了腐蚀剂的供应和腐蚀产物的迁移，而且在流体与金属之间产生切应力，能剥离腐蚀产物，从而加大了冲蚀速度。因此，在管道的拐弯处及流体进入管道或贮罐处容易产生这种破坏。另外，金属表面成膜的特征也可以影响冲蚀速度。硬的、致密的、连续的、粘附性强的膜冲蚀速度小，反之则大。抑制或减少冲蚀的措施是:选择耐蚀性和耐磨性好的材料;改变腐蚀环境如添加缓蚀剂，过滤悬浮固体粒子，降低温度，减小流速和湍流;采用栖牲阳极作阴机保护等。 (1陈树俊l)
