摘要
铝合金在环境中会被腐蚀,对其使用寿命造成影响。基于数字处理技术,利用分形理论对腐蚀试件表面图像进行处理,得到了腐蚀试件表面孔蚀率。涉及的方法具有一定的操作性和工程价值。
Aluminum alloy suffers from corrosion damage in natural environment, which greatly reduces the service life. With the aid of digital image processing technology, fractal theory was introduced to evaluate the corrosion damage parameter, pitting ratio of specimen surface. The proposed method is practical and of engineering value.
