中文摘要：

电气化学的实验被执行测试铝锌的腐蚀率热剧降的涂层。5.3% 铝锌合金(重量比率) 有优异耐蚀性质，这被显示出。坚定的微观结构显示了由纳米组成的非结晶的结构系统的大小的粒子。分析显示了 5.3% 铝锌系统的吉布斯精力的大否定变化。分子的动力学模拟证明 5.3% 铝锌系统从另外的系统有很不同的行为。这个特别系统的阶段转变从模拟被观察。转变温度在 400 K 附近被决定。模拟显示 5.3% 铝锌系统在从 300 ～ 900 K 的温度范围上是非结晶的，支持从铝锌合金的非结晶的固体有的实验的推理特殊耐蚀特性。

英文摘要：

Electro-chemical experiment was carded out to test the corrosion rates of aluminium-zinc hot-dip coating. It is shown that 5.3% aluminium-zinc alloy （weight ratio） has superior anti-corrosion property. The determined microstructure has displayed amorphous structure composed of nanometer sized particle of the system. The analysis indicated large negative change of Gibbs energy of 5.3% aluminium-zinc system. Molecular dynamics simulation showed that 5.3% aluminium-zinc system has very different behavior from other systems. A phase transition of this particular system was observed from simulation. The transition temperature was determined around 400 K. The simulation indicated that 5.3% aluminium-zinc system is amorphous over temperature range from 300 to 900 K, supporting the inference from experiments that amorphous solid of aluminium-zinc alloy has special anti-corrosion character.
