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......
crystals from rod to sphere can be achieved by adding titanium slag to Ti-bearing blast furnace slag. The volume fractions of the rutile crystals in the upper and lower parts of the modified slag are 30% and 71% when the added titanium slag increases to 278 g, indicating that rutile settling is obvious. Due to the rutile settling, half shaker sorting task is saved, and the recovery rate of TiO2......
shows the concentration degree of calcium, aluminum, silicon, titanium, and magnesium in the microstructure of slag. Calcium, aluminum, and silicon are concentrated in a gray structure, and a large... titanium, and the outermost layer comprises slag. With the EDS analysis results of three-pointed phase on Fig. 7, nickel and chromium are concentrated in the pig iron, whereas vanadium is gathered......
Double Glow Plasma Surface Alloyed Burn-resistant Titanium Alloy ZHANG Gao-hui1,ZHANG Ping-ze1,HE Zhi-yong1,XU Zhong1 (1.Taiyuan University of Technology, Taiyuan, Shanxi, 030024, P. R. China) 摘要:Conventional titanium alloy may be ignited and burnt under high temperature, high pressure and high gas flow velocity condition. In order to avoid this problem, we have developed a new kind of burn......
