一种非晶金属与塑料的复合材料、 复合壳件及其制备方法
【技术领域】
本发明属于高分子工程材料技术领域， 涉及一种非晶金属与塑料的复合 材料、 复合壳件及其制备方法。
【背景技术】
非晶金属是原子排列在三维空间无长程有序的金属。 与晶态金属相比， 非晶态金属在物理性能、 化学性能和机械性能都发生了显著的变化。 非晶态 金属位错密度高， 宏观组织均一， 没有晶界等缺陷， 被认为是高韧性、 高强 度的主要原因。
从构造上看， 非晶态金属没有晶界、 层错等缺陷， 没有偏析、 析出及异 相， 当添加适当元素形成亚稳态后， 会显示出惊人的耐腐蚀性， 在酸性、 中 性或者碱性等各种容易中长期浸泡而不被腐蚀， 如在 Fe基合金中添加 Cr和 Mo, 其耐腐蚀性之强， 令人难以置信。
非晶态金属除了高强度、 高耐韧性、 高耐磨性和超耐腐蚀性外， 还具备 耐放射线损伤， 通常中子照射到结晶金属上后， 原子的点阵排列会遭到破坏， 出现很多缺陷使材料性能下降， 但是非晶态金属在放射线长期照射后既不脆 化， 导电性也不下降。
非晶金属通常采用熔体急速冷却法制备，其冷却速度要达到 108°C/s以上 的冷却速度， 其对工艺水平要求非常高， 所以非晶金属很难以大批量生产， 其价格也相对较高， 虽然非晶金属还可以采用通过其他方法生产， 如： 气相 沉积法、 化学溶液反应法以及固相反应法， 但是这些工艺均非常复杂， 难以 批量化生产， 所以目前， 非晶态金属的价格都相对较高。
上述非晶态金属各种优异的机械、 化学、 电学性能使得其可以作为理想 的笔记本电脑、 手机、 掌上电脑等电子产品外壳材料。 但是由于其价格昂贵， 如果将整块笔记本电脑的外壳均采用轻质非晶金属制成， 显然是不恰实际的， 因为其成本还是太高。
【发明内容】
为了解决上述的技术问题， 本发明提出了一种新的非晶金属与塑料的复 合材料， 还提出了采用该非晶金属与塑料的复合材料制成的复合壳件以及它 们的制备方法。

( 1 ) 使非晶金属薄片附着在注塑模腔的内壁上；
(2)从注塑模腔的注塑口中注入熔融塑料， 冷却成型， 使非晶金属层和 塑料层粘接在一起形成一整体。
本发明另提供一种采用非晶金属与塑料复合材料制成的复合壳件， 其特 征在于， 该壳件包括位于壳件最外层的非晶金属层以及与所述非晶金属层粘 接在一起的塑料层，该非晶金属层的厚度为 5~ 1 50 μ ΓΠ，所述塑料层的厚度为 0.2~6mm。

(4 )从注塑模腔的注塑口中注入熔融塑料， 冷却成型， 使非晶金属层和 塑料层粘接在一起形成一整体。
