Mhoro, huya ubvunze zvigadzirwa zvedu!

Nesilicon Boride Upfu, SiB6

Sezvo P-mhando yepamusoro-tembiricha thermoelectric zvinhu kutsiva boroncarbide, inogona kushandiswa seyakajairika muyero hasha, kukuya carbide. Inoshandiswa zvakare seinjiniya zvedongo zvinhu, nenyunje mhuno, yekugadzira gasi mashizha uye mamwe akafuridzirwa sintered zvikamu uye zvisimbiso.

Aluminium borate (AlB2) rudzi rwemhando yezvinhu zvakagadzirwa nealuminium uye boron. Iyo yegrey yakatsvuka yakasimba pasi peyakajairika tembiricha uye kumanikidza. Iyo yakagadzikana muchitonho inoderedza acid, uye yakaora mune inopisa hydrochloric acid uye nitric acid. Icho chimwe chezvikamu zviviri zvealuminium uye boron. Imwe yacho alb12, iyo inowanzonzi aluminium borate. Alb12 idema inopenya monoclinic crystal ine huremu hwakadzama hwe2.55 (18 ℃).

Iyo insoluble mumvura, acid uye alkali. Inoora mune inopisa nitric acid uye inowanikwa nekunyunguduka boron trioxide, sarufa uye aluminium pamwechete.

Muchimiro, maB maatomu anoumba graphite maflakes ane maatomu eAl pakati pavo, ayo akafanana zvikuru nemamiriro emagnesium diboride. Iyo imwechete kristaro yeAlB2 inoratidza simbi conductivity padivi peiyo axis inoenderana ne hexagonal ndege yeiyo substrate. Boron aluminium composites inosimbiswa ne boron fiber kana boron fiber ine yekudzivirira inodzivirira

Izvo huwandu hwehuwandu hwe boron fiber ingangoita 45% ~ 55%. Yakadzika yakadzika simba, yakakwira michina zvivakwa. Iyo yekureba tensile simba uye elastic modulus ye unidirectional yakasimbiswa boron aluminium composite ndeye 1.2 ~ 1.7gpa uye 200 ~ 240gpa, zvichiteerana.

Iyo yakareba yakareba yakasarudzika modulus uye yakatarwa simba ingangoita ka3 ~ ka5 uye ka3 ~ 4 nguva dze titanium alloy duralumin uye alloy simbi, zvichiteerana. Yakave ichishandiswa mune turbojet injini fan mashizha, mota yemuchadenga uye setiraiti zvivakwa. Iyo inopisa yekutsikirira diffusion yekubatanidza nzira inoshandiswa kugadzira mahwendefa, ma profiles uye zvikamu zvine maitiro akaomarara, uye inoramba ichikanda nzira inogona zvakare kushandiswa kugadzira akasiyana profiles.
