摘　　要：针对铝合金压铸模具材料失效主要原因———铝液热浸蚀问题 ,采用电火花沉积工艺 ,利用陶瓷材料与铝液不浸润的特点 ,在铝合金压铸模具材料H13(4Cr5MoSiV)表面沉积金属陶瓷 ,并对沉积前This paper discussed the main reason resulting to thermal abrasion of the aluminum alloy diecast. It is thermal abrasion from molten aluminum. On the basis of non-soaking cerame to molten aluminum, cerament was deposited on the surface of die (4Cr5MoSiV) by electro-sparking deposition(ESD). The paper compared properties of anti-thermal abrasion from molten aluminum of dies before depositing and after depositing.
