Vaongorori veJapan vaongorori vaishandisa polycrystalline madhaimondi madhaimani ekucheka al2o3 ceramics uye si3n4 ceramics. Izvo zvakawanikwa kuti iyo coarse-yakagadzirwa polycrystalline madhaimondi madhaimani madhaimani aive asina kupfeka panguva yekucheka maitiro uye maitiro ekugadzirisa aive akanaka. Kana kucheka ziro2 ceramics nemidziyo yemadhaimani, yakasvika pamhedzisiro yakafanana kana ichicheka simbi. Vakaongorora miganhu yekucheka kwepurasitiki. Iyo inocheka kudzora kudzika kweAl2o3 ndeye APMACE = 2Um, si3n4 ceramic = 4um (AP> AP> APMAC.
