Porous SiC ceramic were prepared with silicon carbide powder as the aggregate, silicone resin as the binder and pore agent by the process of mixing, iso-static pressure molding, and calcination. The mechanical properties and microstructures of the samples were characterized with a universal testing machine, X-ray diffraction, scanning electron microscope, and mercury injection.
04.06.1998· Thermal expansion of the hexagonal (4H) polytype of SiC was measured from 20 to 1000 °C by the x‐ray diffraction technique. The principal axial coefficients of thermal expansion are expressed by the second‐order polynomials: α 1 1 =3.21×10 − 6 +3.56×10 − 9 T−1.62×10 − 1 2 T 2, and α 3 3 =3.09×10 − 6 +2.63×10 − 9 T−1.08×10 − 1 2 T 2 (°C − 1).

Due to their prominent properties (mechanical, stiffness, strength, thermal stability), ceramic composite materials (CMC) have been widely applied in automotive, industrial and aerospace engineering, as well as in biomedical and electronic devices. Because monolithic ceramics exhibit brittle behaviour and low electrical conductivity, CMCs have been greatly improved in the last decade.

One of the major usages for Al–Pb alloy are bearing alloys because of its lubricant behavior of Pb phase component. Appliions of these alloys are in heavy duty, such as boring mills, presses, lathes, milling machines and hydraulic pump bushings. In present work, SiC powder was selected as additive for improving the mechanical properties of Al-Pb alloy that produced by mechanical alloying
The peculiarity of dusty plasma reactors offers a convenient way to obtain processed particles at submicronic levels, with successive layers of different materials grown by using pulsed gas flows, and different plasma chemistries in succession.
