Abstract

本发明提供一种壳体，包括镁或镁合金基体、形成于该镁或镁合金基体上的防腐蚀层及具有装饰性的色彩层。所述壳体具有良好的耐腐蚀性及装饰性外观。本发明还提供了所述壳体的制造方法，包括以下步骤：提供镁或镁合金基体；于该镁或镁合金基体上磁控溅射形成防腐蚀层；于该防腐蚀层上磁控溅射形成具有装饰性的色彩层。

Description

壳体及其制造方法
技术领域
本发明涉及一种壳体及其制造方法。
背景技术
真空镀膜技术(PVD)是一种非常环保的成膜技术。以真空镀膜的方式所形成的膜层具有高硬度、高耐磨性、良好的化学稳定性、与基体结合牢固以及亮丽的金属外观等优点，因此真空镀膜在镁、镁合金及不锈钢等金属基材表面处理领域的应用越来越广。
然而，由于镁或镁合金的标准电极电位很低，且PVD装饰性涂层本身不可避免的会存在微小的孔隙，如针孔、裂纹，并且镁或镁合金基体会发生微电池腐蚀作用，形成很大的膜-基电位差，加快了微电池的腐蚀速率，因此，直接于镁或镁合金基体表面镀覆诸如TiN层、TiN层、CrN层或其他PVD装饰性涂层，不能有效防止所述镁或镁合金基体发生电化学腐蚀，同时该PVD装饰性涂层本身也会发生异色、脱落等现象。
发明内容
鉴于此，提供一种具有良好的耐腐蚀性及装饰性外观的壳体。
另外，还提供一种上述壳体的制造方法。
一种壳体，包括镁或镁合金基体，一形成于镁或镁合金基体表面的防腐蚀层，及一形成于防腐蚀层表面的色彩层，所述防腐蚀层为镁层。
一种壳体的制造方法，包括以下步骤：
提供镁或镁合金基体；在该镁或镁合金基体上磁控溅射形成防腐蚀层，该防腐蚀层为一镁层；于该防腐蚀层上磁控溅射形成色彩层。
所述壳体的制造方法，通过磁控溅射法依次于镁或镁合金基体上形成镁的耐腐蚀层，当壳体处于腐蚀性介质中时，由于镁与镁合金之间的电位差小、兼容性好，且镁膜层与镁合金基体之间的相同及相似金属的亲和性，能增加其膜-基之间的附着力，从而有效降低了膜-基电位差，使壳体较难以形成发生电化学腐蚀所需要的阴极与阳极的条件，从而提高了壳体的耐腐蚀性。所述壳体耐腐蚀性提高的同时，还可避免所述色彩层发生异色、脱落等失效现象，从而使该壳体经长时间使用后仍具有较好的装饰性外观。

图1为本发明较佳实施例的壳体的剖视图。

壳体              10
镁或镁合金基体    11
防腐蚀层          13
色彩层            15
具体实施方式
请参阅图1，本发明一较佳实施例的壳体10包括镁或镁合金基体11、依次形成于该镁或镁合金基体11上的防腐蚀层13及色彩层15。该壳体10可以为3C电子产品的壳体，也可为工业、建筑用件及汽车等交通工具的零部件等。
所述防腐蚀层13为镁层，其厚度为1.0～3.0μm。
所述色彩层15为Ti-N层，其厚度为1.0～3.0μm。
可以理解，所述色彩层15还可以为Cr-N或其他具有装饰性的色彩层。
所述防腐蚀层13及色彩层15均可通过磁控溅射法沉积形成。
本发明一较佳实施例的制造所述壳体10的方法主要包括如下步骤：
提供镁或镁合金基体11，并对镁或镁合金基体11依次进行研磨及电解抛光。电解抛光后，再依次用去离子水和无水乙醇对该镁或镁合金基体11表面进行擦拭。再将擦拭后的镁或镁合金基体11放入盛装有丙酮溶液的超声波清洗器中进行震动清洗，以除去镁或镁合金基体11表面的杂质和油污等。清洗完毕后吹干备用。
对经上述处理后的镁或镁合金基体11的表面进行氩气等离子清洗，进一步去除镁或镁合金基体11表面的油污，以改善镁或镁合金基体11表面与后续涂层的结合力。该等离子清洗的具体操作及工艺参数可为：将镁或镁合金基体11放入一磁控溅射镀膜机(图未示)的镀膜室内，对该镀膜室进行抽真空处理至真空度为1.0×10-3Pa，以400～500sccm(标准状态毫升/分钟)的流量向镀膜室中通入纯度为99.999％的氩气，于镁或镁合金基体11上施加-300～-500V的偏压，对镁或镁合金基体11表面进行等离子清洗，清洗时间为5～10min。
在对镁或镁合金基体11进行等离子清洗后，于该镁或镁合金基体11上形成防腐蚀层13。所述防腐蚀层13为镁层。形成该防腐蚀层13的具体操作及工艺参数如下：以氩气为工作气体，调节氩气流量为100～200sccm，设置占空比为30％～80％，于镁或镁合金基体11上施加-100～-200V的偏压，并加热镀膜室至100～150℃(即溅射温度为100～150℃)；选择镁为靶材，设置其功率为8～13kw，沉积防腐蚀层13。沉积该防腐蚀层13的时间30～60min。
形成所述防腐蚀层13后，于该防腐蚀层13上形成色彩层15，形成该色彩层15的具体操作及工艺参数如下：关闭所述镁靶的电源，开启已置于所述镀膜机内的一钛靶或铬靶的电源，，设置其功率8～10kw，保持上述氩气的流量不变，并向镀膜室内通入流量为20～150sccm的反应气体氮气，沉积色彩层15。沉积该色彩层15的时间为20～30min，该色彩层15为Ti-N膜层或Cr-N膜层。
本发明较佳实施方式的壳体10的制造方法，通过磁控溅射法依次于镁或镁合金基体11上形成镁的防腐蚀层13及色彩层15。当壳体10处于腐蚀性介质中时，由于所述壳体10的镁或镁合金基体11之上形成有防腐蚀层13即镁金属层，由于镁与镁合金之间的电位差小、兼容性好，从而有效降低了膜-基电位差，使壳体10较难以形成发生电化学腐蚀所需要的阴极与阳极的条件，从而减缓了壳体10的腐蚀速率，提高了壳体10的耐腐蚀性。所述壳体10耐腐蚀性提高的同时，还可避免所述色彩层15发生异色、脱落等失效现象，从而使该壳体10经长时间使用后仍具有较好的装饰性外观。
