VaSindamu, Vagadziri, uye maneja ekutakura anofanira kuita chisarudzo chakakosha pakusarudza yakakodzera yekramic ye cramic zvinhu.Boron buri (b4c)uyeSilicon Carbide (Sic)vanozivikanwa nehunyanzvi ceramics nekuda kwekureba kwavo kwakanyanya, kugadzikana kwekunyanyisa, uye kuramba kumamiriro akanyanya. Nekudaro, ivo vanoshandira zvakaringana zvinangwa zvakasiyana-uye kusarudza izvo zvisiri izvo zvinogona kuve nemhedzisiro yemutengo, kusimba, uye zvese zvakazara maitiro.
Iyi yakadzama kutarisisa kuongororaBoron burinaSilicon carbidePanyaya yezvinhu, zvinoshandiswa, zvakanaka, uye zvinodhura kuti zvikubatsire kusarudza kuti ndeipi yeCeramic zvinhu zvakanakira chirongwa chako chakasiyana.
1. Kuongorora kwezvinhu zviviri
Boron buri (b4c)
Boron burindeimwe yezvishandiso zvakaomesesa, chinzvimbo kumashure kwedhaimani uye cubic boron nitride. Iyo ine maronda zvakanyanya, nemakemikari inter, uye inowanzoshandiswa mukuwedzera-mashandiro ekudzivirira uye ekupfeka-zvinopfekwa-zvinodzivirira.
Silicon Carbide (Sic)
Silicon carbideinozivikanwa kwazvo nekuomerwa kwayo kwakakwirira, kufambidzana kweruzivo, uye yepamusoro yekudziya kwekuvhundutsa. Iyo ndiyo inoshanda yeinjiniya ceramics uye kazhinji inodhura kupfuura Buron barbide.
2. Kuenzanisa Zvivakwa: B4C vs.Sic
Chivakwa
| Boron buri (b4c) | Silicon Carbide (Sic) |
| Density | Yakanyanya kuderera (~ 2,52 g / cm³) | Yakaderera / mwero (~ 3.1 g / cm³) |
| Kuomesa | Yakanyanya kukwirira (≈ 30 GPA) | Yakanyanya Kukwirira (≈ 25-28 GPA) |
| Pfeka kuramba | Zvakanaka | Kugona chose |
| Kupunzika kuoma | Kuderera (zvimwe brittle) | Yakakwira (zvirinani kuvhiringidza kuramba) |
| Inobata | Zvine mwero | Yakanyanya kukwirira (yakanakisa kupisa kusarongeka) |
| Kemical Resistance | Zvakanakisa | Zvakanaka |
| Kuita kweballistic | Mukuru | Zvakanaka asi anorema |
| Mutengo | Kumusoro | Zvimwe zvinodhura-zvinobudirira |
3. Rini kusarudzaBoron buri
3.1 yehuremu-inorema-yakaoma zvikumbiro
Boron burizi ndeimwe yeiyo yechiedza cheCeramical ceramics, ichiita kuti ive yakakwana kuhuremerwa uremu pasina kukanganisa kuomarara.
3.2 yekudzivirira kwakanyanya
B4Cisarudzo yakanakisa ye:
Kuomarara kwayo kusingafadzi kunoita kuti ibvise kuvhara mombe dzakakwirira-velocity nehuremu hushoma.
3.3 Yenzvimbo dzakanyanyisa dzabudirira
Boron buriInodarika pa:
Kupfeka kwaro kupesana kunowanikwa munguva refu yekupikisa pane sic mumamiriro ezvinhu akaipisisa.
4. Rini kusarudzaSilicon carbide
4.1 Kune Yakakwira Thermal Discount
Silicon carbideinokodzera:
Inokurumidza kupenga kupisa uye inogona kutsungirira tembiricha yakanyanyisa isina kupaza.
4.2 yemari-inotsvedza maindasitiri mapurojekiti
Sicinozivikanwa nekuti inopa kuita kwakanaka pamutengo wakaderera:
Nozzles
Fani
Michina yezvisimbiso
Kiln Fenicha
Zvimiro Zvemotokari
4.3 Zvemamiriro ezvinhu anoda kukwirisa kumusoro
SIC iri kushoma brittle pane b₄c, zvichiita kuti ive yakawanda nekukanganisa, inambiriro, uye yekudyara.
5. Kuenzanisa
Nepo mitengo chaiyo inotsamira pakuchena, saizi, uye maitiro ekugadzira:
Boron burizvakawandainodhura inodhura nekuda kwekutakura mari yemitengo uye yakajeka kuchinjisa.
Silicon carbide iri kudhura-inobata, kunyanya yezvikamu zvikuru kana zvakakwirira-vhoriyamu kugadzira.
B₄C ndiyo sarudzo yepamusoro yekuwana mashandiro akakwana pane chero mutengo.
Kana iyo yekuita-kune-mutengo chiyero chakakosha, sic inowanzo kuve sarudzo yepamusoro.

8. Conclusion
Vese Boron buri uye silicon carbide yakakwira-precess-prescess ceramics, asi ivo vanokurira munzvimbo dzakasiyana.
Boron cabride-echokwadi kusingaenzaniswi mukuomarara, kuderedzwa kwehuremu, uye kuita kweballistic, kuita kuti zvive zvakanaka zvombo uye zvakakwirira-kupfeka zvigadziriso.
Silicon carbideIne yakanakisa yekudzora, kuoma, uye mutengo-zvinobudirira, zvichiita kuti zvinhu zvakanakisa zvekushandisa maindasitiri uye zvakakwirira-tembiricha.
Iyo yakanakisa ceramic yeiyo application yako inotemerwa nezvayo chaizvo zvinodiwa. Kune akawanda mashandisirwo, ari kuyera uremu, kuomarara, maitiro anowedzera, kuoma, uye bhajeti inotsoropodza kusarudza zvakanakisa.
