Abstract
本发明涉及浇铸含6.0-8.0％Al和3.2-4.3％Cu，其余为Zn的合金的方法。该合金显示细粒浇铸结构，浇铸可在440℃以下进行。本方法尤其适于压铸法制造小型汽车。
Description
本发明涉及一种在橡胶模子里通过离心浇铸或者在金属模子里通过压铸，制备含有铝和铜的锌基合金制品的方法。
一种在橡胶模子里通过离心浇铸，制备含有铝和铜的锌基合金制品的方法，由已由L.S.Schaer，在1977年1月20日出版的杂志Machine Design第113页至117页，所发表题为“Rubber-mold spin-casting for low-cost prototype or productionparts”的文章中描述过。这种已知的方法或者是使用一种含Al3.5％，含Cu3.5％，其余为Zn叫做“Formalloy”的合金，或者是使用一种含Al11％，含Cu1％，其余为Zn叫做“ILZRO-12”的合金(在本专利申请书中所给的所有浓度都是以重量％表示)。Formalloy和ILZRO-12具有的固化温度范围分别为380-390℃和380-432℃，以及它们铸造的温度分别在393-427℃和440-468℃。Formalloy有一个缺点，即凝固开始时有枝晶或玄武岩的形成，这些东西有可能阻碍熔融材料在铸模穴里的循环，而且有引起浇铸缺陷的危险。从ILZRO-12方面来讲，它要求铸造的温度至少在440℃，这将促使制造模子的硅橡胶快速损坏。
一种含有铝和铜的锌基合金制品在文献“铸造的锌合金，一种进步的因素：Zamak合金”里已进行了描述，该文章于1972年11月发表在“锌的工艺中心，PUBLIMAC，92600，Asnieres”。这种已知方法使用一种含Al3.9-4.3％，Cu0.75-1.25％和Mg0.03-0.06％，其余为Zn，叫做“Zamak 5”的合金。Zamak 5完全同Formalloy一样，表现出一种有形成枝晶或玄武岩的倾向的铸造结构。相同类型的其它方法在文献DE-B-1211403，FR-A-1321677和US-A-2467956中有所描述：根据其中第一篇文献，人们使用一种含Al6.7-7.5％，Cu3.2-4.2％和Be0.01-0.1％，其余为Zn的合金，根据第二篇文献，一种含Al1-10％，Cu0.1-5％，Mg＞0.005-0.05％和Be＞0.0001-0.01％，其余为Zn的合金，而根据第三篇文献，一种含Al2.0-10.0％，Cu0.03-3.50％，Mg0.01-0.30％和Be0.00001-0.0001％，其余为Zn的合金。这三种方法都要求用铍作为合金的成分。由于铍在蒸气状态是剧毒的，实施这些方案需要严格的预防措施而这些措施费用太大。
本发明的目的是为了获得一种如上述定义的方法，它能避免这些已知方法的缺陷。
为此，根据本发明的合金包含6.0-8.0％的Al和3.2-4.3％的Cu，其余为Zn，例如电解锌，以及一些不可避免地存在于上述金属中的杂质。
的确，人们找到了这样一种合金，它表现出一种细颗粒的铸造结构以及它能在440℃以下被铸造。这种合金能够在440℃以下被铸造的这一事实，对于离心浇铸是尤其重要的。
铜的含量不能低于3.2％也不能高于4.3％；否则，将会冒产生枝晶或玄武岩倾向的结构的危险。
铝的含量少于6.0％将同样产生一种枝晶的或玄武岩的结构，而铝的含量多于8.0％将把铸造温度降至440℃左右。
合金呈现出一种极好的流动性。
当在压力下铸造合金时，要求在热室里安装一台压铸机是尤其方便。
使用一种含Al6.7-7.3％和Cu3.6-4.0％的合金是有利的，而最好使用一种具有低共熔组成的合金：含Al7.0％，Cu3.8％和Zn 89.2％。事实上，已经发现合金的流动性是随着合金的组成接近低共熔的组成而提高。正如人们同样发现，在合金中杂质的存在对流动性有不利的影响，本发明推荐使用一种合金，其锌的纯度至少达到99.995％，铝的纯度至少达到99.97％和铜的纯度至少达到99.99％。
在本发明的方法中所使用的合金的极好的流动性，由下述一系列Radone类型的流动性试验所给出的结果来说明。这种试验的原理，是在负压和不变的温度下，通过将液态金属抽吸到一根水平管子中，然后，测量吸入金属的长度，这样来试验“浇铸”。这一长度是对金属的可铸造性，即对流度(流动性)的一种测量。
将下列合金进行这种试验：
—在本发明的方法中所使用并在以后将被称为“Superloy”的合金，
—“Superloy”合金，在该合金中加入了0.005％的Be和在以后将被称为“含Be合金”，
—前述的“Zamak 5”合金和其它两种通常用于压铸和被称为“Zamak 2”和“Zamak 3”的合金。合金的固化特性和化学分析：
试验在下列条件下进行：
| 固化(℃) | 化学分析(％) | ||||||||
| 液化温度 | 凝固温度 | Al | Cu | Mg | Pb | Fe | Cd | Be | |
| Superloy | 379 | 379 | 6.90 | 3.70 | 0.001 | 0.0014 | 0.0020 | 0.0002 | - |
| 含Be合金 | 379 | 379 | 6.90 | 3.70 | 0.001 | 0.0014 | 0.0020 | 0.0002 | 0.005 |
| Zamak 2 | 390 | 379 | 4.01 | 2.80 | 0.040 | 0.0015 | 0.0025 | 0.0008 | - |
| Zamak 3 | 387 | 381 | 4.04 | 0.001 | 0.043 | 0.0020 | 0.0021 | 0.0009 | - |
| Zamak 5 | 386 | 380 | 4.06 | 0.880 | 0.044 | 0.0022 | 0.0020 | 0.0009 | - |
—槽的温度： 420℃
—负压： 205mmHg柱
—管子的直径：3mm所吸入金属的长度，以mm计：
Superloy：415
含Be合金：385
Zamak 2：290
Zamak 3：275
Zamak 5：260值得注意的是Superloy的流度比Zamak 2的流度高43％，尽管Zamak 2本身在Zamak s系列中流动性是最好的，但还有更值得注意的是在Superloy中仅仅增加0.005％的Be就使流度降低了8％。
Superloy在室温下表现出下列机械特性：
—抗拉强度：315MPa
—永久伸长0.2％的限度：210MPa
—布氏(Brinell)硬度：95
—伸长率：6％
很明显，为了从本发明的方法中获得最大的好处，在尽可能少地超过合金的液相线温度或低共熔组合物的熔点，例如超5至30℃的一种温度下，进行铸造是恰当的。
本发明所用的压铸方法尤其适用于制备小型汽车。
