空化侵蚀是船舶和流体机械系统面临的主要挑战。本研究研究了两种铸态铝合金在10-50°C的水中暴露于声空化的侵蚀性能，然后将其与挤压变形合金在最大侵蚀温度下的测试进行了比较。结果表明：铸态A380合金具有较好的抗空化腐蚀性能，质量损失最小，表面粗糙度最小；这一发现表明，在抗空化性能至关重要的应用中，铸态A380合金是轻质、高性能部件的合适选择。
Cavitation erosion is a major challenge for marine and fluid machinery systems. This study investigated the erosion performance of two as-cast aluminium alloys exposed to acoustic cavitation in water at temperatures of 10–50 °C and those were then compared with an extruded wrought alloy tested specifically at the temperature of maximum erosion. The results showed that the as-cast A380 alloy displayed exceptional resistance to cavitation erosion, with the lowest mass loss and surface roughness. This finding suggests that the as-cast A380 alloy is a suitable choice for lightweight, high-performance components in applications where cavitation resistance is critical.
