Papa Pale Kaua Seramika Alumina VS Silicon

Pepa pale pōkā seramika (papa pale pōkā)he ʻāpana koʻikoʻi ia o nā lako hana pale pōkā. I kēia manawa, ʻo nā keramika silicon carbide a me nā keramika alumina kiʻekiʻe nā mea keramika pale pōkā ʻelua i koi nui ʻia ma ka mākeke. Ma muli o ka hana ʻana o ke kaʻina hana pale pōkā i kahi manawa pōkole loa, pono nā keramika pale pōkā i nā waiwai hou aku, e like me ka density, porosity, paʻakikī, fracture toughness, elastic modulus, sound velocity a me ka mechanical strength, etc.

Hana ʻia ka pepa ballistic alumina seramika Chemshun me ka pauka alumina maikaʻi loa ma ke ʻano he mea nui. ʻOi aku ka maʻemaʻe o α-Al₂O₃ ma mua o 99%, ʻo ka density he ≥3.9g/cm³, kokoke ka porosity i ka ʻole, a ʻaʻole ʻoi aku ka nui o ka omo wai ma mua o 0.02%. Hiki i ka paʻakikī ke piʻi ma luna o HRA88, ʻo ia ka mea koho mua no nā seramika pale pōkā. ʻOi aku ka pae pale pōkā ma mua o ka pae maʻamau ʻAmelika 3. I ka manawa like, hoʻokō pū ia i nā pono o nā mea kūʻai aku no nā seramika pale pōkā silicon carbide. ʻO ka density he ≥3.1g/cm³, ʻo ka paʻakikī he ≥HRA92, a hiki i ka papa pale pōkā ke hiki i ka American Standard 4.

ʻO ka nui o ka pepa keramika pale pōkā chemshun alumina he 50 * 50 * 10mm a me 50 * 25 * 10mm, a ʻo ka nui maʻamau o ka keramika silicon carbide he 250 * 300mm. Loaʻa i nā mea kūʻai aku nā kikoʻī ʻē aʻe a hiki ke ʻae i ka hoʻopilikino ʻana.
