Structure and erosion resistance of Ni60A/SiC coatting by laser cladding LOU Bai-yang(楼白杨), CHEN Zhen(陈 阵), BAI Wan-jin(白万金), DONG Gang(董 刚) MOE Key Laboratory of .... The microstructure and hardness of the coatings were studied by SEM and XRD. The erosion resistances of Ni60A and Ni60A/SiC coatings were also investigated. The results show that the structure of different......
amplitude distribution of end and cylindrical surface was obtained through amplitude spectrum correction for the vibration series based on interpolation method, and cavitation erosion test... analysis of large ingots ultrasonic vibration cavitation system molten aluminum DONG Fang, LI Xiaoqian, ZHANG Min (State Key Laboratory of High Performance Complex Manufacturing, School of Mechanical......
Two-flow model for piping erosion based on liquid-solid couplingLIANG Yue(梁越)1, 2, WANG Jun-jie(王俊杰)1, 2, LIU Ming-wei(刘明维)1, 2(1. National Engineering Research Center for Inland Waterway Regulation...)Abstract:Previous studies have indicated that piping erosion greatly threatens the safe operation of various hydraulic structures. However, few mathematical models are available to perfectly describe......

Effect of Al content on high temperature erosion properties of arc-sprayed FeMnCrAl/Cr3C2 coatings LUO Lai-ma(罗来马)1, LIU Shao-guang(刘少光)2, YU Jia(俞 佳)1, LUO Juan(罗 娟)1, LI Jian(郦 剑)1 1... were analyzed by optical microscopy (OM) and X-ray diffractometry (XRD). High temperature erosion (HTE) tests were performed in an erosion tester at different impact angles. The surface morphologies......
surface in static HA solution, which reveals moderate corrosion of coating without erosion, as shown in Fig. 5(a). On the contrary, in corresponding cavitation case, the features of erosion-corrosion..., as mentioned above, coating surfaces in the other two cavitation solutions seem a little cleaner than those in static cases, but the erosion-corrosion sites can be observed in cavitation SA solution......
jets. The cavitation noise increases with the increase of pump pressures, and changes as the same as that in the cavitation water jets approximately. On the other hand , in the rock erosion... pressure, and the best ambient pressure for cavitation domino is 1 MPa. Key words: bubble cloud; noises of cavitation; submerged abrasive water jets; erosion capability ......
