With the help of an electromagnetic stirring device self-made and alloy melt quenching technology,the effect of electromagnetic stirring parameters on the micro
The residual stresses on the surface of the differently ground and polished silicon nitride ceramics were measured using X-ray diffraction and identified by SEM
The main cause to the deactivation of ZSM-5 catalyst, used for oxidation of benzene to phenol (BTOP)by nitrous oxide, is that the carbon deposition on the catal
Homogeneous HA coating materials were prepared on porous titanium by the low-temperature combustion synthesis. It was found that the mechanical properties of th
A novel bifunctional dye containing spirobenzopyran and cinnamoyl moiety has been prepared and its photochromic behavior following irradiation at different wave
The bioactive α-Ca3 (PO4)2 bone cement was studied by XRD , SEM and isothermal calorimetric measurements. The results showed that a mixed pattern of TCP and hy
The bonding of solid steel plate to liquid aluminum was studied using rapid solidification. The relationship models of interfacial shear strength and thickness
The aim of this work was to produce a nanoscale fluoridated and potassium containing hydroxyapatite via sol-gel method and to observe the effect of occlusion of
Three cement samples were prepared, including OPC consisted of 100wt% portland cement, PFA consisted of 70wt% portland cement and 30wt% fly-ash, and CA consiste
In recent years,materials with ultrafine grain size(UFG) have attracted much attention.By using severe plastic deformation(SPD) techniques,materials with fine g
The distribution of microelement Fe, Si, Cu and Mg in the surface layer of aluminum foil annealed at 300℃ and 500℃ were determined by secondary ion mass spect
