摘要
介绍了分形理论及其特点,简要论述了自相似分形分维和多重分形谱分析方法,对它们在整体腐蚀形貌、点蚀形貌、应力腐蚀、腐蚀机理等方面的应用进行了阐述,比较了两种分形方法的应用特点,分析了今后分形理论在腐蚀领域中的应用趋势。
Fractal theory and geatures are mentioned. Various methods are proposed to estimate the fractal di- mention of a self-similar object and analyze multifractal spectral of a signal. Application of fractal theory on global cor- rosion morphology, pitting corrosion morphology, stress corrosion and corrosion mechanism are stated. In addition, trends of fractal theory which are applied in the evaluation of corrosion morphology are presented by a comparative study of self-similar fractal and multifractal analysis.
