摘要
针对电解加工多孔表面特点,提出表面形貌评价指标,获取多孔表面图像并对其进行预处理,提取腐蚀率、不均匀度、灰度等特征参数,揭示各特征参数与电解加工多孔表面形貌的相关性,并通过实例证明该方法适用于电解加工多孔表面的测量。
Aiming at ECM （electrochemical machining） porous surface characteristics, the surface morphology evaluation parameters are proposed to get the porous surface image for pretreatment. The image characteristic parameters, sueh as degree of corrosion, unevenness and the gradation are calculated. The correlation between each characteristic parameters and porous surface is revealed. The example shows that the method is suitable for measuring ECM porous surfaces.
