Erosion–corrosion behavior of SAF3207 hyper-duplex stainless steelHong-liang Xiang1,2,Yu-rui Hu1,Hua-tang Cao3,Dong Liu1,Xuan-pu Dong41. School of Mechanical Engineering and Automation, Fuzhou... hyper-duplex stainless steel under various conditions were measured. The damaged surfaces after erosion–corrosion tests were characterized by scanning electron microscopy. The results showed......
, speeds of ships, cavitations and erosion corrosion. The environmental factors such as cavitation and corrosion will cause damage for materials with the shock wave by the creation and destruction... that the diameters of pits generated on the specimen surface by cavitation erosion were greater than those of air bubbles [2]. The effects of the flow velocity and environmental solution on cavitation damages......
An experimental study on size distribution and zeta potential of bulk cavitation nanobubblesXu-yu Zhang1,Qian-shuai Wang1,Zhong-xian Wu1,Dong-ping Tao1,21. School of Mining Engineering, University... have a significant impact on the nanobubble flotation performance. In this paper, bulk nanobubbles generated based on the principle of hydrodynamic cavitation were investigated to determine the effects......
of Ministry of Education (Jilin University), Changchun 130022, China)Abstract:A new approach which adopted the idea of coupling bionics to improve erosion resistance was presented, by taking the desert scorpion as the research object. The anti-erosion characteristic rules and mechanism of desert scorpion’s surface under the dynamics effect of gas/solid mixed media were researched, especially......
; Erosion characteristic of slope sandstone soaking in acid mine drainage JIANG Li-chun(姜立春)1, CHEN Jia-sheng(陈嘉生)2, WU Ai-xiang(吴爱祥)2 (1. Institute of Safety... original sandstone and AMD eroded sandstone samples show that after AMD erosion the uniaxial compressive strength and elastic modulus decrease by 30%-50% and 25%-45%, respectively, the cohesion......

Arc erosion of AgSnO2 electrical contacts at different stages of a break operationJ. Swingler,A. SumptionSchool of Engineering Sciences,University of Southampton摘 要:Arc erosion studies are conducted on AgSnO2 contact materials at different stages in the break operation.A resistive load arrangement is used with up to 42 V DC at 24 A and a constant......
Preparation and Arc Erosion Resistance of C_f/Cu Composite by Vacuum Melting Infiltration张华煜1,LIU Yiwen2,ZHAO Xianling1,LUAN Xingang21. College of Material Science and Engineering, Taiyuan University... erosion rate of Cf/Cu composite was investigated in vacuum. The results showed that the Tiand Cr could improve the wettability between Cu and C/C preform and the infiltration ability of Cu into C/C......
Microstructure and Erosion Resistance of in-situ SiAlON Reinforced BN-SiO2 Composite Ceramics田卓,DUAN Xiaoming,YANG Zhihua,YE Shuqun,贾德昌,ZHOU YuInstitute for Advanced Ceramics,School of Materials... plasma flow generated by HallThruster was used for sputtering the surface of the samples in order to evaluate the plasma erosion resistance.XRD,TEM,SEM,and LSCM were used to characterize the phase......
Improved similarity criterion for seepage erosion using mesoscopic coupled PFC–CFD modelNI Xiao-dong(倪小东), WANG Yuan(王媛), CHEN Ke(陈珂), ZHAO Shuai-long(赵帅龙) (Key Laboratory of Ministry of Education... used to investigate seepage erosion. However, the centrifugal test method may not be efficient according to the results of hydraulic conductivity tests and piping erosion tests. the reason why......
