Abstract: | The strength enhancement of non-oxide structural ceramics (carbides, borides etc) has always been a major challenge. To this end, the effect of pre-oxidation on strength of silicon carbide with ground surface, machined using diamond wheels with varying grit sizes of 127m, 64 m, 42 m, 32 m, was investigated. The experimental results showed that the room temperature strength of ground specimens was improved because both grinding-induced-cracks and pre-existing surface flaws were healed during oxidation in air. After heat-treating, the strength measurements indicated a constant value of about 470 MPa, independent of the surface condition. Moreover, the strength remained almost constant up to 14000C, when the ground specimen was heat-treated at 15000C for 50h in air. |
