- Abstract:为研究中性盐雾加速腐蚀钢结构表面形貌分形维数,开展了7个批次的H型钢人工加速腐蚀试验,借助三维非接触式表面形貌仪对截取的锈蚀H型钢翼缘板进行了表面形貌扫描并获取了三维形貌坐标数据,采用盒宽变换法编程计算了锈蚀表面分形维数并研究其随腐蚀龄期、质量损失率以及表面粗糙度变化规律。结果表明,锈蚀钢板表面形貌具有分形特征;腐蚀初期(龄期小于6个月)钢板表面曲线以及曲面分形维数均随腐蚀龄期增长而不断增大,同时增大趋势不断减缓,当腐蚀龄期超过6个月后分形维数开始出现减小-增大-减小的上下波动;锈蚀钢板横截面曲线分形维数呈一定的各向异性,轧制方向分形维数略大于板宽方向;试验拟合得到锈蚀钢板表面分形维数与腐蚀龄期、质量损失率以及表面粗糙度平均高度的相关关系,可以用作中性盐雾腐蚀钢板的表面形貌表征。
