(I-BN-AlN-TiB2 Composite Evaporation BoatIkhiqizwe nguWintrustek)

Isingeniso:

II-BN-AlN-TiB2 Composite Evaporation Boatiwumthombo osebenza kakhulu, ohlala isikhathi eside womthombo wokuhwamuka owenziwe ngobuchwepheshe obusha benhlanganisela ye-ceramic. Akuyona into eyodwa kodwa iyinhlanganisela yesikali esincane kanye nenhlanganisela efanele eyenziwe ngomklamo onembile. Lokhu kuhlanganisa kuhlanganisai-boron nitride (BN)ukuthambisa kanye nokumelana nokushaqeka kwe-thermal,i-aluminium nitride (AlN)ukuqhutshwa kwe-thermal high and insulation, kanye ne-titanium diboride (TiB2) ye-conductivity ephezulu kagesi kanye nokumelana nokugqoka. Umgomo uwukwakha umkhiqizo ophumelelayo owenza ngaphezu kwezinto ezivamile ezivamile, njenge-graphite noma i-quartz, ezimeni zokusebenza ezinzima.

Idizayinelwe ngokukhethekile izindawo zezimboni ezidinga amazinga okushisa aphezulu, amagagasi aphezulu, ukugqwala kwensimbi enamandla okuncibilika, nokuhamba ngebhayisikili okushisayo okusheshayo, ukwakheka kwempahla eyingqayizivele yesikebhe sokuhwamuka kanye nenqubo ye-sintering kusivumela ukuthi sigcine ukuguquguquka kukagesi kokushisa kokumelana ngenkathi igcina amandla nokuzinza kwezitsha zobumba zesakhiwo. Lokhu kubhekana ngempumelelo nezingqinamba ezinkulu ezikebheni zakudala zokuhwamuka, njengokuqhekeka, ukuhlanekezela, ukungena kwensimbi, nempilo yesevisi enomkhawulo.

Inzuzo:

I-Boron Nitride (BN)

• Inikeza ukuthambisa okusezingeni eliphezulu okuvelele ngenkathi yehlisa ukunamathela kokusebenza.

• I-coefficient ephansi yokwandisa okushisayo inyusa ukumelana nokushaqeka kokushisa.

• Ukumelana okuphezulu kuthuthukisa ukusatshalaliswa kwamanje futhi kuvimbela ukushisa okweqile kwendawo.

I-Aluminium Nitride (AlN)

• High conductivity thermal kubangela homogeneity ezishisayo kangcono.

• Ukwahlukanisa okukhulu nokuzinza kwezinga lokushisa eliphezulu.

• Ukwenyuka kwamandla emishini nokumelana nokuguguleka.

I-Titanium Diboride (TiB2)

• I-conductivity ephezulu kagesi iholela ekushiseni okuphumelelayo kwe-Joule.

• Ubulukhuni obuphezulu kakhulu kanye nokumelana nokugqoka kukhulisa impilo yesevisi.

• Ukumelana ne-oxidation okuhle kakhulu kuzivumelanisa nezimo ze-oxygen ephezulu.

Isicelo:

1. I-vacuum Coating

• Ukuhwamuka kwamafilimu ensimbi, njenge-aluminium, isiliva, nethusi (ama-electrode e-photovoltaic angemuva nama-optical coatings).

• Ama-electrode ensimbi alungiselelwa amadivaysi e-semiconductor.

2. Ukucutshungulwa Kwezinto Ezisezingeni Eliphezulu

• Nikeza ukwesekwa kokukhula kwekristalu yesafire.

• Izitsha ezishisayo zokushisa eziphezulu zezimpushana ze-ceramic.

3. Ucwaningo Lwesayensi Nezinqubo Ezikhethekile

• Imithombo yokuhwamuka yezingxenye zengxenye ye-aerospace.

• Ukubekwa kwezinto ezimboziwe zokusetshenziswa kwezikhali zenuzi.

Isiphetho:

Izikebhe ze-TiB2-BN-AlN eziyinhlanganisela ye-ceramic evaporationasetshenziswa kabanzi embonini yokuhwamuka kwensimbi ngenxa yezinzuzo zezinto eziyinhlanganisela, ezihlanganisa indawo ephezulu yokuncibilika, ukuqina kwamakhemikhali aphezulu, ubulukhuni obukhulu, ukuhanjiswa okuhle, kanye ne-coefficient yokushisa ye-Resistivity ye-TiB2, ukufakwa kukagesi, ukumelana nokugqwala kwensimbi encibilikisiwe, ukumelana nokushaqeka okuhle kakhulu kwe-thermal, kanye nokusebenza kahleBN, kanye ne-insulation ephezulu kanye nokumelana nokushaqeka okushisayo kweI-AlN.
