초록
Weibull statistical analysis on mechanical properties was performed on silicon carbide by immersion in acidic and alkalinesolution. The heat treatment was carried out on 1373 K. The corrosion of silicon carbide was conducted in acidic and alkalinesolution under KSL1607. Results showed that heat treatment in air could significantly increase the strength of the siliconcarbide. The strength of the corroded and cracked specimen was similar to that of the cracked specimen. The bending strengthof the corroded, crack healed specimen decreased 47% and 75% more than that of the crack healed specimen in acidic andalkaline solution, respectively. The corrosion of silicon carbide is faster in alkaline solution than in acidic solution. Theprobability distributions of Vickers hardness closely followed the Weibull distribution. The scale parameter and shapeparameter are evaluated in as-received silicon carbide and corroded silicon carbide, respectively.
