Abstract This work focuses on the comparison of microstructure and tribological behaviour (dry sliding vs. 100Cr6 steel) of anodic layers produced on wrought AA6082-T5 by hard anodizing (HA), plasma electrolytic oxidation (PEO, sometimes also termed MAO, Micro-Arc Oxidation) and novel electro-chemical oxidation (ECO), derived from PEO minimising its disruptive plasma discharge. The results showed that PEO and HA do not decrease the coefficient of friction of AA6082, whilst ECO does (particularly after sealing with a phosphate-based solution), thanks to its smooth surface and decreased stability of Fe–O based transfer layers. All the anodizing treatments improve wear resistance of AA6082: ECO showed the highest wear resistance, due to the beneficial combination of compact microstructure, high and uniform thickness, high microhardness and adhesion.

通过传统和创新处理对 AA6082-T5 进行阳极氧化：微观结构表征和干滑动行为

摘要 这项工作的重点是通过硬质阳极氧化 (HA)、等离子体电解氧化 (PEO，有时也称为 MAO、微弧) 在锻造 AA6082-T5 上生产的阳极层的微观结构和摩擦学行为 (干滑动与 100Cr6 钢) 的比较。氧化）和新型电化学氧化 (ECO)，源自 PEO，最大限度地减少其破坏性等离子体放电。结果表明，PEO 和 HA 不会降低 AA6082 的摩擦系数，而 ECO 会（特别是在用磷酸盐基溶液密封后），这是由于其光滑的表面和降低的 Fe-O 基转移层的稳定性。所有阳极氧化处理都提高了 AA6082 的耐磨性：ECO 表现出最高的耐磨性，这是由于紧密的微观结构、高且均匀的厚度、高显微硬度和附着力的有益组合。
