Silicon carbideisimbi yakagadzirwa nesilicon uye kabhoni maatomu akarongwa muchimiro chekristaro chakanyatsobatanidzwa. Kurongeka kweatomu kwakasiyana uku kunoipa zvinhu zvinoshamisa: yakada kuoma sedhaimani (9.5 pachikero cheMohs), yakareruka katatu pane simbi, uye inokwanisa kushingirira tembiricha inodarika 1,600°C. Pamusoro pezvo, yakakwira yekupisa conductivity uye kugadzikana kwemakemikari inoita kuti ive yakanaka kune yakanyanya-kushushikana nharaunda.
Mauto Zvikumbiro: Kudzivirira Hupenyu muKurwa
Kwemakumi emakore, mauto ehondo ave achitsvaga zvinhu zvinodzikamisa kudzivirira uye kufamba. Nhumbi dzesimbi dzechinyakare, nepo dzichishanda, dzinowedzera huremu hwakakosha kumotokari nevashandi. Silicon carbide ceramics yakagadzirisa dambudziko iri. Kana ichishandiswa mumubatanidzwa masisitimu ezvombo — kazhinji akaturikidzwa nezvinhu zvakaita se polyethylene kana aruminiyamu — SiC ceramics inokunda pakukanganisa nekuparadzira simba remabara, shrapnel, uye zvidimbu zvinoputika.
Mota dzemazuva ano dzemauto, mahwendefa ezvombo zvemuviri, uye zvigaro zvechikopokopo zvinowedzera kubatanidza SiC ceramic mapaneru. Semuyenzaniso, ngowani dzehondo dzechizvarwa cheU.S dzinoshandisa SiC-based composite kuderedza huremu uku ichichengetedza dziviriro kubva kumakwikwi epfuti. Saizvozvo, lightweight ceramic armor kits yemotokari dzakashongedzwa inovandudza kufamba pasina kukanganisa kuchengetedza.
Mamiriro Evanhu: Kuchengetedzeka Kupfuura Nzvimbo Yehondo
Izvo zvimwe chete zvivakwa zvinoita kuti SiC ceramics ive yakakosha muhondo ikozvino iri kushandiswa kudzivirira veruzhinji. Sezvo mutengo wekugadzira uchidzikira, maindasitiri ari kutora iyi "super ceramic" nenzira dzekugadzira:
1. Zvombo zveMotokari: Vatungamiri vepamusoro-soro, vamiriri, uye motokari dzeVIP ikozvino dzinoshandisa dzakangwarira SiC ceramic-reinforced panels for bullet resistance, kubatanidza umbozha nekuchengeteka.
2. Muchadenga & Mujaho: Zvikwata zveFormula 1 nevagadziri vendege vanobatirira mahwendefa eceramic matete eSiC muzvikamu zvakakosha kuti vadzivirire kubva kumarara pakumhanya kwakanyanya.
3. Kuchengetedzwa Kwemaindasitiri: Vashandi vari munzvimbo dzine njodzi (semuenzaniso, kuchera, kugadzira simbi) vanopfeka giya risingachinjiki rakasimbiswa neSiC ceramic particles.
4. Consumer Electronics: Kuedza kushandiswa kunosanganisira ultra-durable smartphone kesi uye heat-resistant casings yemabhatiri emotokari yemagetsi.
Iyo yakanyanya kupararira kushandiswa kwevanhu, zvisinei, iri mumarata ekudzivirira eceramic. Aya mapaneru akareruka ave kuwanikwa mu:
-Mudzimi wemoto giya rekubvisa marara anodonha
-Drone dzimba dzekudzivirira kudhumhana
- Midhudhudhu yekukwira masutu ane abrasion-resistant armor
-Chengetedza zvidzitiro zvebhangi uye nzvimbo dzine njodzi huru
Matambudziko Neramangwana
Nepo silicon carbide ceramics ichipa mabhenefiti asingaenzaniswi, brittleness yavo inoramba iri muganhu. Mainjiniya ari kugadzirisa izvi nekugadzira zvinhu zvakasanganiswa - semuenzaniso, kunyudza maSiC fibers mumatrices epolymer - kuwedzera kuchinjika. Kuwedzera kugadzirwa (3D kudhinda) kweSiC zvikamu zvakare kuri kuwana traction, zvichigonesa maumbirwo akaomarara ekugadzirisa edziviriro mhinduro.
Kubva pakumisa mabara kusvika pakuchengetedza hupenyu hwemazuva ese, silicon carbide ceramics inoratidza kuti hunyanzvi hwemauto hunogona sei kushanduka kuita maturusi anoponesa hupenyu. Sezvo tsvagiridzo ichienderera mberi, isu tinogona kukurumidza kuona SiC-yakavakirwa nhumbi dzokurwa mune zvekuvakisa zvisingaite kudengenyeka, zvivakwa zvisingaite moto wemusango, kana kunyange tech inopfekwa yemitambo yakanyanyisa. Munyika umo zvinoda kuchengeteka zvinoramba zvichiwedzera kuoma, iyi ceramic inoshamisa inomira yakagadzirira kusangana nedambudziko-rimwe rakareruka, rinonyanya kuoma panguva.
