Abstract Porous mullite ceramics were prepared from mixtures of Egyptian kaolinite-clay and calcined α-alumina powder. The effects two methods compaction as well types binder investigated. influence sintering temperature on the physical properties, crystalline phase, compressive strength microstructure was studied. Mullite bodies processed by uniaxial pressing utilizing 15wt. % water at 1500°C ...

Taking the mechanical seal of submersible as object, a transient coupled heat transfer model was established, and deformation face under stable alternating conditions investigated by considering thermal–mechanical coupling effect. The characteristics two different alternative forms amplitude period were analyzed. morphology wear measured discussed based on pseudo-real test loads. results showed...
