Abstract: Manufacturing methods related to anodizing of metal parts are described. In particular, pre-anodizing and post-anodizing methods for forming a consistent and defect-free interface between metal and non-metal sections of a part are described. Methods involve preventing residues from various manufacturing processes from entering a gap or space at the interface between the metal and non-metal section of the part and that can disrupt subsequent anodizing and anodic film dyeing processes. In particular embodiments, methods involve forming a barrier layer or filler layer between the metal and non-metal sections. Portions of the barrier layer or filler layer can be removed prior to anodizing. The resultant part has a well-defined and uniform space between the metal and non-metal sections that is free from visual defects.

Abstract translation: 描述与金属部件的阳极氧化相关的制造方法。 特别地，描述了用于在零件的金属和非金属部分之间形成一致且无缺陷的界面的预阳极氧化和后阳极氧化方法。 方法包括防止各种制造过程的残留物进入部件的金属和非金属部分之间的界面处的间隙或空间，并且可能破坏随后的阳极氧化和阳极膜染色过程。 在具体实施方案中，方法包括在金属和非金属部分之间形成阻挡层或填料层。 在阳极氧化之前可以去除阻挡层或填料层的一部分。 所得部件在没有视觉缺陷的金属和非金属部分之间具有明确且均匀的空间。
