Aluminium diboride AlB2 poda

2, Iyi yakakosha alloy ine yakanaka kupfeka kuramba, kupisa kupisa, oxidation kuramba, kuramba uye tembiricha zvine hukama hwemutsara.Inogona kushandiswa simbi ceramic, kupfeka-inodzivirira coating, yakakwirira tembiricha kuramba, crucible lining, kuzadza uye anti-corrosion. pfapfaidza makemikari midziyo. Iyo zvakare inogona kushandiswa seyakanyanya-yakaoma inorganic zvinhu.

3, inogona kutsiva iyo silicon simbi pepa, kupfuura 50% simba rekuchengetedza.

4, kuve neimwe application muindasitiri yenyukireya, maroketi nozzles, tembiricha mabearings, thermoelectric protection tube, auto parts uye kumwe kugadzira.

Aluminium borate (AlB2) imhando yebhinari musanganiswa wakagadzirwa nealuminium uye boron.

Iro grey dzvuku yakasimba pasi petembiricha yakajairika uye kumanikidzwa. Iyo yakagadzikana mumhepo inotonhora dilute

asidhi, uye yakaora mune inopisa hydrochloric acid uye nitric acid. Ndechimwe chezviviri

masanganiswa ealuminium uye boron. Imwe yacho inonzi alb12, inowanzonzi aluminium

borate. Alb12 ikristaro nhema inopenya yemonoclinic ine giravhiti chaiyo ye2.55 (18 ℃).

Haina kunyungudika mumvura, asidhi uye alkali. Inoora mune inopisa nitric acid uye inowanikwa

nekunyungudutsa boron trioxide, sulfur nealuminium pamwechete.

Muchimiro, maatomu eB anoumba ma graphite flakes ane maatomu eAl pakati pawo, izvo zvakanyanya

zvakafanana nechimiro che magnesium diboride. Iyo imwechete crystal yeAlB2 inoratidza simbi

conductivity pamwe neaxis parallel kune hexagonal ndege ye substrate. Boron

aruminiyamu macomposites anosimbiswa ne boron fiber kana boron fiber ine inodzivirira coating.

Huwandu hwehuwandu hweboron fiber hunenge 45% ~ 55%. Yakaderera chaiyo giravhiti, yakakwirira

mechanical properties. Iyo longitudinal tensile simba uye elastic modulus ye unidirectional

yakasimbiswa boron aluminium composite inenge 1.2 ~ 1.7gpa uye 200 ~ 240gpa, zvichiteerana.

Iyo longitudinal yakananga elastic modulus uye chaiyo simba ndeye 3 ~ 5 nguva uye

3 ~ 4 nguva yetitanium alloy duralumin uye alloy simbi, zvichiteerana. Yakashandiswa mu

turbojet injini fan blades, aerospace mota uye setiraiti zvimiro. Kutsikirira kunopisa

diffusion bonding nzira inoshandiswa kugadzira mahwendefa, profiles uye zvikamu zvine yakaoma

maumbirwo, uye inoenderera yekukanda nzira inogona zvakare kushandiswa kugadzira akasiyana ma profiles.
