英文摘要	Wetting of Q235 steel and pure Ti by Al 6061 alloy were studied by modified sessile drop method at 600~700 under high vacuum. The results showed two systems were typically reactive wetting, and the wettability was improved with the increase of temperature. The negligible effect of interfacial reactivity on final wettability and interfacial structures, and the solubility of base metal in Al determined the thickness of reaction layer (the larger solubility and the larger thickness). Reduction reaction at close of triple line induced the formation of precursor film (the better final wettability and the wider precursor film). The spreading dynamic, both of these two wetting systems could be described by RPC model. For Al/Ti system, the wetting behaviors could be divided into two stages, i.e., first nonlinear spreading and then linear spreading, the activation energies for these two stages were 72 kJ/mol, 118 kJ/mol, and Si segregation at the solid/liquid interface could be found. For Al/Q235 steel system, only one linear spreading stage could be found, the activation energy was 86 kJ/mol, and almost no trace of Si segregation at the solid/liquid interface was found. © 2017, Materials Review Magazine.
