J. Cent. South Univ. (2012) 19: 887-891 DOI: 10.1007/s11771-012-1088-0 Fabrication and plasma arc thermal shock resistance of HfB2-based ultra high temperature ceramics WENG Ling(翁凌)1, HAN Wen-bo(韩文波... and the thermal shock resistances were evaluated by plasma arc heater. The results indicate that the composite with AlN as sintering additive has a denser and finer microstructure than composite without......
THE EFFECTS OF NEGATIVE BIAS AND FLUX RATIO ON THE PROPERTIES OF TiN THIN FILMS FORMED BY FILTERED CATHODIC ARC PLASMA TECHNIQUE J.Wang1,W.W. Zhang1,Z.G. Wu1,Q.J. Xue2,Y.J.Zhang1,P.X. Yan1...) Abstract:The filtered cathodic vacuum-arc (FCVA) technique is a supplementary and alternative technique with respect to convendtional physical and chemical vapour deposition which can remove macro-particles......
An evaluation analysis method for corrosion morphology characterization based on Gaussian filter ZHANG Peng (张 鹏)1, GUO Bin (郭 斌)2, CHENG Shu-kang (程树康)3 1. School of Materials Science... through the experimental bench. According to surface variation of samples during corrosion process, the surface model of specimen was build up based on Gaussian filter. The results show......

School of Physical Science and Technology, Lanzhou University,Lanzhou 730000, China) Abstract: Ni nanopowders were successfully prepared in large quantities by anodic arc discharged plasma method......
Ni/Al Intermetallics Plasma Transferred Arc Processing Ana Sofia C. M. D'Oliveira1,Ver2 (1.Mechanical Engineering Department, Federal University of Parana, Curitiba/Brazil;2.o)nica A. B. Almeida(o... the possibility to strengthen surface components with alloys that would not be possible to process otherwise. This work used Plasma transferred arc (PTA) hardfacing for surface alloying. Different amounts......
PARTICLE SIZE AND MICROSTRUCTURE OF Ni NANOPOWDERS PREPARED BY ANODIC ARC PLASMA H.X. Qiao1,Z.Q. Wei2,W.J. Feng2,Q.Wang2,J.F. Dai2,P.X. Yan3 (1.College of Civil Engineering, Lanzhou University...) Abstract:Pure Ni nanopowders were successfully prepared by the method of anodic arc discharged plasma with homemade experimental apparatus. The particle size, mircostructure and morphology......
; 文章编号:1672-7207(2018)10-2454-08 Influence of convex tooth radius of flexspline on tribology of double circular arc harmonic gear transmission PEI Xin1, ZHOU Guangwu1..., a mixed lubrication mathematical model of flex-spline and soft-spline in meshing area of double circular arc tooth profile harmonic reducer was established. The influence of different tooth profile......
Design and Analysis of Microstrip Multi-Channeled Filter Using Photonic Crystal Branchy Defect He Li1,Chen Hong1,Jiang Haitao1,Li Yunhui1,Zhang Yewen1,Li Hongqiang1 (1.Pohl Institute of Solid State Physics, Tongji University, Shanghai 200092, China) Abstract:A multi-channeled filter based on branchy defect in a microstrip photonic crystal was proposed. By introducing a branchy structure across......
