(I-BN-AlN-TiB2 Isikhephe esidityanisiweyo soMphungaIveliswe nguWintrustek)

Intshayelelo:

II-BN-AlN-TiB2 Isikhephe esidityanisiweyo soMphungangumthombo osebenza kakhulu, ohlala ixesha elide ongumthombo ongundoqo wecandelo elenziwe ngobuchule obutsha be-ceramic composite technology. Ayiyomathiriyeli enye kodwa ingumdibaniso we-micro-scale kunye nomxube ofanelekileyo owenziwe ngoyilo oluchanekileyo. Lo mxube ubandakanyai-boron nitride (BN)ukuthambisa kunye nokumelana nokothuka kwe-thermal,ialuminiyam nitride (AlN)kwi-conductivity ephezulu ye-thermal kunye ne-insulation, kunye ne-titanium diboride (i-TiB2) ye-conductivity ephezulu yombane kunye nokuxhatshazwa kokugqoka. Injongo kukuphuhlisa imveliso ephumelelayo edlula izinto eziqhelekileyo eziqhelekileyo, ezifana negraphite okanye i-quartz, kwiimeko zokusebenza ezinzima.

Idizayinelwe ngokukodwa iimeko zemizi-mveliso ezinobushushu obuphezulu, imisinga ephezulu, isinyithi esinobundlongondlongo sokunyibilika, kunye nokuhamba ngokukhawuleza kwebhayisikile eshushu, ukwakheka kwezinto ezizodwa zesikhephe somphunga kunye nenkqubo yokucoca ivumela ukuba igcine umbane wokufudumeza ukuxhathisa ngelixa igcina amandla kunye nokuzinza kweeseramikhi zesakhiwo. Oku kujongana ngempumelelo nemiqobo ephambili kwizikhephe zomphunga zakudala, ezinje ngokuqhekeka, ukugqwetheka, ukungena kwentsimbi, kunye nobomi benkonzo obunyiniweyo.

Inzuzo:

IBoron Nitride (BN)

• Inikezela ngokugqwesileyo kubushushu obuphezulu ngelixa unciphisa ukuncamathela kwezinto.

• I-coefficient ephantsi yokwandiswa kwe-thermal yongeza ukuxhathisa ukothuka kwe-thermal.

• Ukumelana okuphezulu kuphucula ukuhanjiswa kwangoku kwaye kuthintele ukugqithiswa kwendawo.

IAluminiyam Nitride (AlN)

• Ukuqhuba okuphezulu kwe-thermal kubangela i-homogeneity engcono ye-thermal.

• Ukugquma okukhulu kunye nokuzinza kobushushu obuphezulu.

• Ukonyuka kwamandla oomatshini kunye nokumelana nokhukuliseko.

I-Titanium Diboride (TiB2)

• I-conductivity ephezulu yombane ikhokelela ekufudumeni okusebenzayo kwe-Joule.

• Ubulukhuni obuphezulu kunye nokumelana nokunxiba kwandisa ubomi benkonzo.

• Ukuxhathisa okugqwesileyo kwe-oxidation kulungelelanisa kwiimeko eziphezulu ze-oksijini.

Isicelo:

1. I-Vacuum Coating

• I-Evaporation yeefilimu zetsimbi, ezifana ne-aluminium, isilivere, kunye nobhedu (i-photovoltaic back electrode kunye neengubo zokukhanya).

• Ii-electrode ezenziwe ngesinyithi zilungiselelwe izixhobo ze-semiconductor.

2. Ukwenziwa kweMathiriyeli yobushushu obuphezulu

• Ukubonelela ngenkxaso yokukhula kwekristale yesafire.

• Iinqanawa zokushisa eziphezulu ze-sintering ze-ceramic powders.

3. UPhando lobuNzululwazi kunye neeNkqubo eziZodwa

• Imithombo yokuphuphuma kwamanzi yokwalekwa kwecandelo le-aerospace.

• Ukubekwa kwezinto ezigqunyiweyo zezixhobo zenyukliya.

Isiphelo:

I-TiB2-BN-AlN i-composite ye-conductive ceramic evaporation izikhephezisetyenziswa kakhulu kushishino lwentsimbi engumphunga ngenxa yeenzuzo zezinto ezidibeneyo, ezidibanisa indawo ephezulu yokunyibilika, uzinzo oluphezulu lweekhemikhali, ukuqina okuphezulu, ukuhanjiswa okuhle, kunye nomgangatho wobushushu ofanelekileyo we-TiB2, ukugqunywa kombane, ukunyathela kwisinyithi esinyibilikisiweyo, ukuxhathisa ukothuka kwe-thermal, kunye nokusebenza kakuhle kombane.BN, kunye ne-insulation ephezulu kunye ne-thermal shock resistance ofAlN.
