theory, the mechanism of temperature change in stator rubber lining was studied, and the coupled thermal-structure effect on stator rubber lining was analyzed with the finite element simulation. The temperature field distribution characteristics, thermal stress and strain law were analyzed. The effects of rubber hardness, Poisson ratio, static pressure, rotor speed, strata temperature and differential......
-quality aluminum ingots, improve aluminum quality and enhance both mechanical properties and processing performance [1-3]. It is widely used in modern aluminum fabrication by adding grain refiners... study of each refiner, 750 g commercial purity aluminum (abbr. pure Al) was melted in a graphite crucible using an electrical resistance furnace. When the temperature of molten aluminum reached 720 °C......
is regarded as the most significant development in metal joining in a decade, and FSW has some merits, such as high retention of bulk mechanical properties, low distortion, low residual stresses and low defects joining technology, which is applied in the fields of aerospace industry and transportation industry extensively [5-7]. The friction stir spot welding (FSSW), a variant of FSW, has......
their development in the field of high temperature [2]. To improve the anti-oxidation performance of C/C composites, a protective coating is applied to the surface of C/C composites [3,4]. MoSi2 is known... coating including the low ductility at ambient temperature, the pest oxidation in the intermediate temperature range, the poor strength at high temperature and CTE mismatch between MoSi2 coating (8......
. The microstructure and the anti-oxidation performance of the coating at 1773 K are investigated. The thermal shock tests between 1773 K and room temperature (RT) are investigated. 2 Experimental Specimens with size... and compact SiC coating was obtained by low pressure chemical vapor deposition. The microstructures and phase compositions of the coatings were characterized by SEM, EDS and XRD analyses. Oxidation behaviour......
