Sintered SiC Ceramics: Pono o SiC Ceramic Ballistic Products
Silicon carbide ceramic huahana pale paleke lilo nei i mea kaulana loa ma ke kahua o ka pale pilikino a me ka pūʻali koa ma muli o kā lākou hana maikaʻi loa a me ka hana. Loaʻa i kēia mau seramika kahi SiC maʻiʻo ≥99% a me kahi paʻakikī (HV0.5) ≥2600, e hana ana iā lākou i mea koho no nā noi ballistic e like me nā pale pale pale a me nā mea pale no nā pahu a me nā kaʻa kaua.
ʻO ka huahana nui o kēia pūʻulu ʻo ka silicon carbide ceramic bulletproof sheet. ʻO kona haʻahaʻa haʻahaʻa a me ke kaumaha māmā e kūpono loa ia i nā mea pale pōkā o kēlā me kēia koa, ʻoi aku hoʻi e like me ka uhi o loko o nā lole pale pale. Eia kekahi, hāʻawi ia i nā pōmaikaʻi nui e pili ana i ka lōʻihi, ka ikaika a me ke kūpaʻa wela.
Loaʻa i nā seramika Silicon carbide (SiC) ʻelua mau hale aniani, cubic β-SiC a me hexagonal α-SiC. Loaʻa i kēia mau seramika nā paʻa covalent ikaika, ʻoi aku ka maikaʻi o nā waiwai mechanical, ka pale ʻana i ka oxidation, ka pale ʻana a me ka coefficient haʻahaʻa o ka friction ma mua o nā ceramics e like me ka alumina a me ka boron carbide. ʻO kā lākou hoʻoili wela kiʻekiʻe, ka helu liʻiliʻi o ka hoʻonui ʻana i ka wela, a me ke kūpaʻa maikaʻi i ka haʻalulu wela a me ka corrosion kemika e hoʻomaʻamaʻa i kā lākou mau noi ākea.
ʻO ka loina pōkā o ka silicon carbide ceramics aia i kona hiki ke hoʻopau a hoʻopaʻa i ka ikehu pōkā. ʻOiai ʻo nā mea ʻenekinia kuʻuna e hoʻomoʻa i ka ikehu ma o ka hoʻololi ʻana i ka plastic, nā mea seramika, me ka silicon carbide, e hana pēlā ma o microfractures.
Hiki ke hoʻokaʻawale ʻia ke kaʻina hana hoʻoheheʻe ʻana o ka silicon carbide bulletproof ceramics i ʻekolu mau pae. I ka wā o ka hopena mua, pā ka poka i ka ʻili seramika, hoʻopololei i ka pōkā a haki i ka ʻili seramika, hana i nā wahi ʻāpana liʻiliʻi a paʻakikī. I ka wā o ka erosion, hoʻomau ka pōkā pōpō i ka ʻāʻī ʻana i ka wahi o ka ʻōpala, e hana ana i kahi papa mau o nā ʻōpala keramika. ʻO ka hope loa, i ka wā o ka deformation, māwae a me ka haʻihaʻi ʻana, ua hoʻokau ʻia ka ceramic i nā koʻikoʻi tensile, e alakaʻi ana i kona haki ʻana. Hoʻopau ʻia ke koena o ka ikehu e ka deformation o ka mea backplate.
ʻO kēia mau waiwai maikaʻi a me ke kaʻina hana hoʻoheheʻe ikehu ʻekolu e hiki ai i ka silicon carbide ceramic ballistic huahana ke hoʻopau maikaʻi i ka hopena o nā pōkā a hoʻolilo iā lākou i mea pōʻino. ʻO ka helu pōkā a hiki i ka pae maʻamau ʻAmelika 4, e hāʻawi ana i ka pale kiʻekiʻe loa a ʻo ia ka koho mua o ka poʻe loea koa ma ka honua.
I ka hōʻuluʻulu ʻana, loaʻa i nā ʻano huahana kīwila silicon carbide sintered a me nā moʻo huahana ʻoi aku ka maikaʻi ma ke ʻano o nā waiwai mechanical, thermal stability, and bulletproof efficiency. Me kā lākou mau waiwai maikaʻi, hoʻohana nui ʻia kēia mau seramika e like me nā mea hoʻonaninani no nā ʻaʻahu pale a me nā mea pale no nā kaʻa a me nā kaʻa kaua. ʻO kā lākou haʻahaʻa haʻahaʻa a me ke kaumaha māmā e kūpono iā lākou no ka pale ballistic pilikino. Ke hoʻomau nei ka ʻenehana i ka holomua, hiki iā mākou ke manaʻo i nā hoʻomohala hou a me nā noi o kēia mau seramika kupaianaha i ka pale pilikino a me ka pūʻali koa.
