表面处理常见问题解答
我该如何为我的加工零件选择合适的表面处理？
选择理想的表面处理取决于您零件的环境。对于室内美观，通常阳极氧化或珠砂喷砂是最佳选择。对于恶劣的户外或工业环境，我们推荐硬阳极氧化（类型 III）、粉末涂层或电泳涂层以获得优越的耐腐蚀性和耐用性。
表面处理会影响我零部件的最终公差吗？
是的，一些工艺会增加厚度。化学转化涂层（如黑氧化）或钝化对尺寸几乎没有影响。然而，粉末喷涂可以增加50–100微米，而硬质阳极氧化则会显著增加厚度。在XY-Global，我们的工程师在初始CNC加工阶段考虑这些变化，以确保最终的完美贴合。
铝制CNC零件最适合哪些表面处理？
阳极氧化是铝材最受欢迎的选择，提供出色的耐磨性和颜色选择。铝材的其他优秀选择包括珠砂喷砂以获得哑光质感，以及铬酸盐转化以提高电导率和防腐蚀能力。
您能匹配特定品牌颜色吗？
当然。我们提供粉末喷涂、喷漆和阳极氧化，可选择多种定制颜色。
“外观性”与“功能性”表面处理有什么区别？
外观性处理（如镜面抛光或 PVD 镀膜）侧重于零件的视觉美感和表面质感。而功能性处理（如钝化或化学镀镍）则旨在提升零件的机械性能，例如硬度、润滑性或耐化学腐蚀性，此时外观表现通常处于次要地位。
哪种表面处理工艺在小批量生产中具有最短的交货时间？
对于小批量生产，最快的表面处理工艺包括手工抛光/打磨、不锈钢钝化以及手工喷漆——应避开粉末喷涂等工艺复杂且固化周期长的处理流程。
