ALUMINUM OXIDE-BASED COMPOSITE SINTERED MATERIAL AND CUTTING INSERT
摘要
<p>A cutting insert (1) is formed by an aluminum oxide-based composite sintered material which comprises a three-component ceramics material of aluminum oxide, silicon carbide and a sialon. The sialon in the aluminum oxide-based composite sintered material is composed of Si-Al-O-N as defined in accordance with JCPDS No. 32-0026 in X-ray diffraction analysis.</p>
