of these samples had been tested by determination of the stable pitting potential in 0.5M and 1M NaCl at 25℃. For the investigated steel composition and the used corrosion system there is no influence of molybdenum on the effectiveness of nitrogen. The influence of nitrogen to all of the determined parameters can be corrosion tests. Additionally surface investigations with an acid elektolyte (0,1M HCl + 0,4M......
Mechanism and Influence Factors of V6O13 Synthesis林勤,杜垣胜,叶文,刘康,刘人敏,李晓云摘 要:<正> The mechanism and influence factors of thermal decomposition of NH4VO3 in Ar to produce V6O13were investigated by TG-DTG, DSC, X-ray diffraction and orthogonal design experiments at 25~450℃.Theprocess includes four reactions, among which the reduction of V2O5 by NH3......
