Effect of flank angle and friction coefficient on contact stress of turbine rotorWU Xiao-zan(伍晓赞), TAO Qing-bin(陶庆斌), CHEN An-ping(陈安平), XU Hui(徐慧)(1. School of Physics Science and Technology... in aeroengine, based on the ANSYS, the simplification model of the turbine rotor was built up. By applying the simplification model, the contact stress of turbine rotor was computed. The maximum contact......
are in contact with each other. For the irreversible reaction, the gas-solid reaction will happen, so long as the reactant solid and gas are in contact with each other. But for reversible reaction, the gas-solid reaction will happen, when not only they are in contact with each other but also the concentration ratio of product gas to reactant gas is below the equilibrium constant in ambient. So......
Influence on Rolling Contact Fatigue Life of GCr15 Steel Treated by Plasma Immersion Ion Implantation TANG Bao-yin1,SUN Tao1,LIU Dan1,HU Li-guo2,WNAG Lang-ping1,WNAG Xiao-feng1 (1.State key lab...-on-rod testing, the rolling contact fatigue (RCF) life of GCr15 steel treated by PIII technique was studied. During the study, nitrogen plasma was generated and the implantation voltage was varied from 20......
Microstructure and properties of CuCr contact materials with different Cr contentXIU Shi-xin1, YANG Ren2, XUE Jun3, WANG Jin-xing3, WANG Jia-yi1(1. State Key Laboratory of Electrical Insulation...:In order to study effect of Cr content on microstructure and properties of CuCr contact material, three different Cr content contact materials, named CuCr25, CuCr30 and CuCr40, were manufactured by vacuum......
A New AgMeO Contact Material 唐红梅1,温鸣1,王宝珠1,王景芹1,陆俭国1,吕玉申1 (1.Department of Electrical Engineering, Hebei University of Technology,) Abstract:A new silver rare earth oxide contact material... and mechanical properties of Ag/SnO2(12) and Ag/CdO(12), the properties of three contact materials are similar, and hence Ag/La2O3(12) may become a potential contact material to be used as the substitute of Ag......
, Harbin 150001, China)Abstract:A line contact model of elastic coated solids is presented based on the influence coefficients (ICs) of surface displacement and stresses of coating-substrate system and the traditional contact model. The ICs of displacement and stresses are obtained from their corresponding frequency response functions (FRF) by using a conversion method based on fast Fourier......
CONTACT MATERIALS FOR GaSb AND InSb: A PHASE DIAGRAM APPROACH K.W.Richter1,H.Ipser1 (1.Institut für anorganische Chemie,Universitat Wien Wathringerstrasse 42,A-1090 Vienna,Austria) Abstract... as these contacts will be stable even after long exposure to elevatedtemperatures. These possible candidates for contact materials may be directly obtainedfrom the phase diagrams.During the last years we......

. The simple theory discussed for the growth of a reaction product by solid state diffusion between reactants originally in contact, predicts that the thickness of IMC layer is proportional to the square root... Abstract: Intermetallic compounds(IMC) formed at Sn-Ag-Cu solder droplet/pad interface during wetting reaction were investigated. Comparative studies of the IMC evolution during reflow......
