对阳极氧化木纹着色工艺中的关键环节——多孔阳极氧化膜的生长进行了探讨。发现凡经着色后能得到浓淡差异、色彩鲜明的表面,其结构是坟路内多孔膜厚于其外的区域。壁垒膜的存在对多孔膜的生长有一个延迟阻碍作用,壁垒膜越厚,多孔膜的生长受到的延迟阻碍作用越大。木纹电解结束后,铝合金表面有壁垒膜存在,纹路内壁垒膜薄,其外厚且均匀。 The key part of the anodized wood coloring process - porous anodic oxide film growth were discussed. Found that after the color can be shades of difference, bright surface, the structure is grave road porous film thicker than the outside of the area. The presence of the barrier film has a retarding effect on the growth of the porous film, and the thicker the barrier film, the greater the retardation effect on the growth of the porous film. After the end of the wood grain electrolysis, there is a barrier film on the surface of the aluminum alloy, and the inner wall of the grain barrier film is thin and thick and uniform outside.
