Strong interfacial bond affects mechanical and wear properties of Al-MMC. The purpose of this work is to investigate the effect of Mg on wear characteristics of silicon carbide (SiC) and alumina (Al 2O 3) reinforced Al-MMC. Al-MMC reinforced with varying wt. % of
The introduction of silicon carbide high voltage Schottky Diodes will shift these paradigms. Due to their superior characteristics, the design guidelines must be rewritten. 3 Properties of silicon carbide With silicon carbide, belonging to the so called wide
Silicon carbide (SiC) porous substrates are prepared by pressureless sintering of SiC powders under an inert atmosphere of argon. The porous SiC substrates were characterized by measuring their porosity, pore size distribution, surface characteristics, and structure. Their transport characteristics were investigated using N2 and He as the test gases. Three different starting powders and four
