The shallow penetration depth of the sealant was often the main reason affecting its long-term protection. For the purpose of improving the penetration depth of the sealant and prolong its durability, an ultrasonic-assisted pre-sealing, annealing plus post-impregnating integration sealing method...

The fabrication process of Si-steel thin-strip by twin-roll continuous casting was described and the quality of the obtained Si-steel thin-strip was measured. Si-steel strips with 0.5–6.5 wt.% Si content were successfully prepared, and proper parameters including pouring temperature, height of...

ZrO2-Al2O3 laminated ceramics of 3 layers were prepared by dry-pressing and pressureless sintering, and their mechanical properties and toughening mechanisms were studied. Furthermore, their tribological behaviors and wear mechanisms under dry friction and water lubrication conditions were also...

In this paper, by using β-SiC powder as a matrix and mixing different content of C, a series of SiC–C composites with solid phase sintering under different temperature were prepared. The relative density, electrical properties and microwave absorption properties at X band were measured...
