Trans. Nonferrous Met. Soc. China 25(2015) 2473-2480 Kinetics of reactive wetting of graphite by liquid Al and Cu-Si alloys Di Zhang1, Ding-yi Zhu1, Teng ZHANG1, Qin-feng WANG1, 2 1. College... January 2015 Abstract: In order to reveal the physical essence of the spreading process of reactive wetting, a sort of model of energy to explain the driving force and wetting mechanism......
on wetting were studied systematically. The results show that in the electromagnetic field, the order of contact angles for the molten Ti50Al alloy for the eight oxide materials is θ(Y2O3)＞θ(ZrO2(Y2O3))＞θ(ZrO2(CaO))＞θ(CaO)＞θ(ZrO2(MgO))＞θ(Al2O3)＞θ(Zircon)＞θ(MgO). The wetting process of Ti50Al alloy and ceramic moulds includes the nonreactive wetting at the first stage, and the reactive wetting......

characteristics of SWP and wetting characteristics was examined.As a result,it was found that spatial characteristics of the SWP affected the wetting characteristics and the oxidation characteristics......
="ChDivSummary" name="ChDivSummary">The corrosion behavior of type 1045(AISI) carbon steel(CS) in oil-water fluids was investigated by considering the surface wetting state as the breakthrough point.The surface water wetting percentage(SWWP)and corrosion weight loss of CS in different oil-water fluids were measured.The morphology and composition of the corrosion films were detected via scanning electron......
-wetting phase on a fractal rough surface increases with increasing fractal dimensions, and both the critical nucleus radius and the nucleation energy barrier decrease with increasing fractal dimensions for heterogeneous nucleation of a wetting phase on the fractal rough surface. For a non-wetting system, the critical nucleus radius shows a slight shift with changes of the intrinsic wetting angle......

October 2013; accepted 21 November 2014 Abstract: The wetting behavior between liquid aluminium and substrates made from industrial Al2O3 and SiC based ceramic foam filters (CFF) was investigated......
and Sn-8Zn-3Bi-(0-0.15)La solder melts. Wetting balance method was used to measure wetting force and wetting time on Cu substrate of the two group solders. The experimental results show that minute amount of Nd.... Nd or La addition has the effect on enhancing the wetting force of the solder melts on Cu substrate, which results from the decrease of interfacial tension between the solder melt and Cu substrate......

Abstract: Intermetallic compounds(IMC) formed at Sn-Ag-Cu solder droplet/pad interface during wetting reaction were investigated. Comparative studies of the IMC evolution during reflow and aging were also conducted. The results show that the wetting reaction between molten solder droplet and pad leads to the formation of Au-Sn compound at interface, but Au element is not fully consumed......
