摘　　要：气蚀是压铸过程中产生的一种较为特殊的模具腐蚀类型,与日常所见的如冲蚀,化学腐蚀比较,既有相同点又具独特性,且随着压铸自动化程度的提高和新工艺的应用,危害日渐明显。本文以实际压铸过程中的经验总结为基础,分析模具气蚀的表象,形成机理,特点,进而探究对于模具气蚀的预防和修复解决方法。Cavitation is a kind of special mold corrosion in die casting process.Compared with common corrosion,such as erosion and chemical corrosion,cavitation has both similarities and peculiarities,with the improvement of die-casting automation and the application of new technology,the harm is more and more obvious.Based on the experience of actual die casting process,this paper analyzes the appearance,Formation Mechanism and characteristics of Die Cavitation,and then probes into the prevention and repair methods of die cavitation.
