Academy of Sciences, Shenyang 110016, China Received 10 April 2006; accepted 25 April 2006 Abstract: The effects of reactive gas partial pressure on droplet formation, deposition rate and change......
Influence of oxygen partial pressure on properties of N-doped ZnO films deposited by magnetron sputtering WANG Jin-zhong(王金忠)1, 2, E. ElANGOVAN2, N. FRANCO3, A. ALVESE3, A. REGO4, R... frequency (RF) sputtered on glass substrates and studied as a function of oxygen partial pressure (OPP) ranging from 3.0?10-4 to 9.5?10-3 Pa. X-ray diffraction patters confirmed the polycrystalline......
Partial melting and re-solidification in partially melted zone during gas tungsten arc welding of AZ91 cast alloy T. P. ZHU1, Z. W. CHEN2, W. GAO1 1. Department of Chemical... in constitutional liquation in the original interdendritic regions and in the formation of a partially melted zone (PMZ). In this study, gas tungsten arc welding (GTAW) and partial melting (simulated using......
temperature 3.3 Effect of oxygen partial pressure In the process of pressure leaching, oxygen was an important reactive substance introduced into reacting system. The effect of oxygen partial pressure... temperature 150 ℃, oxygen partial pressure 1 MPa, additive amount 1%, solid-to-liquid ratio 1:4, leaching time 2 h, initial sulfuric acid concentration 15%, and particle size......
. The influence of temperature and trans-membrane pressure on hydrogen separation and permeation was also carried out. The gas permeation and selectivity demonstrate that this membrane may have... pressure (101.3 kPa) and from the applied partial pressure at the feed side of the membrane (60 kPa). 3 Results and discussions 3.1 Characterization of Co-IM-mIM crystals Figures 2(a) and (b) show X-ray......
was discussed. The optimized conditions, spraying distance of 220 mm, powders delivering gas pressure of 0.3 MPa and preheating temperature of 240 ?C to sprayed particles, were obtained from orthogonal... and sluggish gas. Powder delivering ratio was about 20 g/min. Three key spraying parameters, namely spraying distance, delivering gas pressure and preheating temperature to agglomerated particles, were......
) in the chamber. The base pressure was 1×10-3 Pa. Mixture of argon (99.99%) and oxygen (99.99%) was used as sputtering gas. The oxygen volume fraction was kept constant at 30%, with working pressure changed... with sputtering pressure. But at a high sputtering pressure, mean free path of gas molecules is very short, whereas the collision of particles becomes frequent in the chamber. Due to collision, particles lost......
