中文摘要 | 本研究係使用SUS-304不鏽鋼材料製成嵌件(Insert)後,以重力鑄造配合熱浸純鋁或純鋅等處理,製備A356鋁合金與不鏽鋼嵌件接合鑄件,探討製程參數包括熱浸材料、熱浸時間、熱浸溫度等,對擴散層厚度及接合強度之影響。實驗結果顯示,熔融A356鋁合金與熱浸純鋁後之不鏽鋼嵌件進行鑄造接合後,其接合界面反應物在靠近不鏽鋼側部份之組成近似於Fe�涉l�ㄛ�;而在靠近A356鋁合金側之介金屬層之組成則接近FeSiAl�ㄛ菕C而熔融A356鋁合金與熱浸純鋅後之不鏽鋼嵌件進行鑄造接合後,接合界面反應物之組成則近似FeSiAl�ㄛ菕C當A356鋁合金與熱浸鋁不鏽鋼接合件的擴散層厚度達10-15μm左右,抗拉強度可達80MPa左右,爾後抗拉強度隨著擴散層厚度增加而減少。當A356鋁合金與熱浸鋅不鏽鋼接合件的擴散層厚度達5-10μm左右,抗拉強度可達110MPa左右,爾後抗拉強度隨著擴散層厚度增加而減少。 |
英文摘要 | In this study the cast welding of molten A356 aluminum alloy to SUS-304 stainless steel was investigated. Galvanized coating and hot dip aluminising on the stainless steel insert was examined and its effects on the bonding strength of the molten A356 Al alloy to the stainless steel insert were evaluated. SEM/EDS and EPMA analysis on the interface of A356 Al alloy/galvanized or aluminised ferrous inserts casts revealed that the interfacial products formed in the course of cast welding between the A356 Al alloy and the stainless steel insert consisted of one or several compound layers. In the case of A356/aluminised SUS-304 stainless steel insert specimen, it was found that the compound product in the SUS-304 stainless steel side was basically of Fe�涉l�ㄈith some Si, Cr and Ni and that in the A356 Al alloy side was of FeSiAl�� with some Si, Cr and Ni. While in the A356/ galvanized SUS-304 stainless steel specimen, the interfacial compound product was found to be the same mono-layer product of FeSiAl�� with a Zn content lower than 2 at . The bonding strength of the A356 Al alloy to the stainless steel insert was found crucial to the nature and the thickness of the compound layer formed between the A356 Al alloy and the stainless steel insert. The maximum bonding strength obtained in the A356/aluminised SUS-304 stainless steel and A356/glavanized SUS-304 stainless steel specimens were 80 and 110 MPa, respectively, when the thickness of their interfacial compound products were in the range of 10-15 and 5-10 μm, respectively. |
