In seawater and fresh water, aluminum alloy was not corroded as the all protection of alclad. In salt lake, the alclad on LC4 aluminum alloy remaindered for half a year, and used up for one year. The base of LC4 aluminum alloy was corroded seriously.

在海水和淡水中，包铝层可以对铝合金基材起到完全的保护作用，使基材免遭腐蚀；而在盐湖水中，半年时LC4铝合金表面尚有包铝存在，而一年时LC4铝合金表面包铝已完全消耗至尽，LC4的基体发生严重腐蚀。

According to SEM observation, the corrosion regulation of LC4 aluminum alloy with alclad in China water system and the protection of alclad on LC4 were studied. The corrosion experiment was done in seawater of Qingdao, Zhoushan, Xiamen, salt lake with high salinity of Geermu, and fresh water of Changjiang River in Hankou.

利用带包铝LC4铝合金在东部地区海水、西部地区盐湖水、中部地区淡水中的暴露腐蚀试验，对盐湖水中包铝对铝合金基体的保护作用行为进行了探讨，得到带有包铝的LC4铝合金在水系统中的腐蚀规律。

Instead, the erosion resistance is increased after FSP. The refined and uniformly distributed second phases, which are resulted from the FSP, can help to increase the hardness and further reduce the brittle fracture of the specimens. Si and nvAl3CuNi phases are usually found near or end of the grooves with little fracture. But the τ1 (Al9FeNi) phase is easier to be removed by the erodent cutting. It can be inferred that Si and nvAl3CuNi are useful to improve the erosion resistance of A384 aluminum alloy, but τ1 (Al9FeNi) phase is detrimental for the erosion resistance of A384 aluminum alloy.

经摩擦搅拌制程改质后，硬度提升，晶出相细化且均匀分布，降低脆性龟裂的现象发生，有助於改善A384铝合金的磨耗性质，其中，亦发现在冲蚀沟槽附近有残留和脆性破裂之共晶Si颗粒和nvAl3CuNiw晶出相，推测此两相为A384铝合金中有助提升磨耗阻抗的第二相；而τ1(Al9FeNi)晶出相则容易受到冲蚀颗粒的切削而被冲蚀颗粒移除，增加材料的重量损失，推测τ1(Al9FeNi)晶出相为A384铝合金中较不耐磨耗的晶出相。

Based on the quality and safty use of the 1000mm Al. alloy die casting steps, we meliorated the 15kg weight step to achieve the result for saving the material cost and production cost, increasing the value for the customer, and raising customer's market competition ability.
