the intrinsic value. The wettability of the Sn-based solder is enhanced with increasing the Sn content. Thus, the wetting mechanism is a series of complex multiple reactions of removing oxide film and it is exceedingly strong. The final wettability of Co73Si10B17 is affected by the interfacial reaction product and surface oxide film, but it is determined by the degree of removal of the oxide film......

of the two kinds of anodized titanium alloys were compared.It was revealed that electropolishing generated a high quality substrate and improved the corrosion resistance of anodic oxide film formed on titanium alloy Ti-10V-2Fe-3Al.Furthermore,the mechanism of electropolishing improving the corrosion resistance of the anodic oxide film was proposed.关键词:......
systematically. The results show that high titanium slag has good microwave absorption property; untreated high titanium slag mainly consists of crystalline compounds of anatase and iron titanium oxide, while the microwave-irradiation treated one is mainly composed of crystalline compounds of rutile and iron titanium oxide. Synthetic anatase is transformed completely into rutile at about 1 050 ℃ for 20 min......
Confining effect of oxide film on tin whisker growthYushuang Liu1,Peigen Zhang1,Jin Yu1,Jian Chen1,Yamei Zhang2,Zhengming Sun11. Jiangsu Key Laboratory of Advanced Metallic Materials,School... to be modulated by oxide film. A striated whisker morphology forms as growing in air, whereas a faceted morphology forms in vacuum.Furthermore, the evolution to the faceted morphology is attributed......
Effect of electrolysis voltage on electrochemical reduction of titanium oxide to titanium in molten calcium chlorideLIU Meifeng, LU Shigang, KAN Surong, and LI Guoxun General Research Institute... using the scanning electron microscopy (SEM) and X-ray diffraction (XRD) techniques. The results show that Ti2O was reduced to low valent titanium oxide at 1.5-1.7 V, which was the result......

Ceramic Conversion Treatment of Titanium Aluminide for Improved Tribological Properties Tom Bell1,JING Xia2,Hanshan DONG1,Chenxi LI2 (1.Dept of Metallurgy and Materials, The University of Birmingham, Birmingham B15 2TT, UK;2.Ad. Surf. Eng. Ltd, Birmingham Research Park, Birmingham B15 2SQ, UK) 摘要:Gamma-based titanium aluminides have great potential in the automotive industries (e.g. valves......
. On the sites where the fluoride film is not complete or dense, oxide (MgO/Mg(OH)2) can be formed after samples are taken out of the activation solution, since magnesium has a very high chemical activity and the formation of magnesium oxide on the surface is rapid. Additionally, the different activation solutions and pretreatment affect the composition of fluoride film, particularly on the F/O ratio......
titanium films with ion dose increasing, except for the group with the highest ion dose of 4× 1017 ions/cm2. XPS depth profiling displayed that sodium entered titanium film around 25-50 nm depth depending on its implantation ion dose. AFM characterization showed that sodium ion implantation treatment changed the surface morphology from a relatively smooth titanium film to rough surfaces......
