Gukoresha ifu ya Boron Carbide
Borb karbideni umukara wa kirisiti hamwe nicyuma cyinshi, kizwi kandi nka diyama yumukara, nikintu kidasanzwe kidasanzwe.Ubukomere bwa karbide ya boron ni nyuma ya diyama na nitride ya cubic boron, kandi irashobora gukomeza imbaraga nyinshi mubushyuhe bwo hejuru, ishobora gukoreshwa nkibikoresho byiza birinda ubushyuhe bwo hejuru;ubucucike bwa karbide ya boron ni nto cyane (ubucucike bwa theoretical ni 2,52 g / cm3 gusa), bworoshye kuruta ibikoresho rusange bya ceramic birashobora gukoreshwa mukibuga cyindege;karbide ya boron ifite imbaraga zikomeye zo kwinjiza neutron, guhagarara neza kwubushyuhe, hamwe no gushonga kwa 2450 ° C, bityo rero ikoreshwa cyane mubikorwa bya kirimbuzi.Mugihe kimwe, ubushobozi bwa neutron yo kwinjiza Birashobora kurushaho kunozwa wongeyeho B element;boron carbide ibikoresho bifite morphologie yihariye nuburyo bifite imiterere yihariye yifoto;hiyongereyeho, karbide ya boron ifite aho ishonga cyane, modulus yo hejuru ya elastique, coeffisiyeti yo kwaguka nkeya hamwe nubushobozi bwiza bwo kwinjiza ogisijeni, nibindi byiza. inganda za gisirikare.Kurugero, ibice birwanya ruswa kandi birinda kwambara, gukora ibirwanisho bitagira amasasu, inkoni zo kugenzura ibintu hamwe nibikoresho bya termoelektrike, nibindi.
Ibyingenzi byingenzi bya boron karbide nibi bikurikira:
1.Gukoresha polishing abrasive
Ikoreshwa rya boron karbide nkibisebanya ahanini ni ugutonesha safiro.Mubikoresho bya superhard, ubukana bwa boron karbide iruta iyoaluminiumna carbide ya silicon, gusa iruta diyama na cubic boron nitride.Boron karbide abrasive (Mohs gukomera 9.3) nibikoresho byiza cyane byo gutunganya no gusya kristu ya safiro.Iyo karbide ya boron iri hejuru ya 600 ℃, ubuso bwayo buzaba okiside muri firime ya B2O3, izoroshya kurwego runaka.Kubwibyo, ntibikwiriye gusya byumye hamwe nubushyuhe bukabije mubisabwa, ariko kubisya gusa.Nyamara, uyu mutungo urashobora gukumira okiside ya B4C, ituma igira inyungu zidasanzwe mugukoresha nabi.
2.Gukoresha ibikoresho byangiritse
Borb karbide ifite ibiranga okiside hamwe nubushyuhe bwo hejuru.Ubusanzwe ikoreshwa nkibikoresho byateye imbere kandi bigizwe na amorphous mubice bitandukanye bya metallurgie, nk'itanura ryibyuma, ibikoresho byo mu itanura, nibindi. Carbide ya Boron izoroshya mubushyuhe bwinshi, bityo irashobora kwizirika hejuru yizindi ngingo zifatika.Nubwo ibicuruzwa byiyongera, firime ya B2O3 ya okiside hejuru yayo irashobora gukora urwego runaka rwo kurinda kandi ikagira uruhare mukurwanya okiside.Muri icyo gihe, kubera ko inkingi ya kristu yakozwe na reaction ikwirakwizwa muri matrix no mu cyuho cyo kuvunika, ubukana buragabanuka, imbaraga z'ubushyuhe bwo hagati ziratera imbere, kandi kwaguka kwinshi kwa kristu yakozwe bishobora gukiza kugabanuka kwijwi kandi gabanya ibice.
3.Gukoresha ibikoresho bitagira amasasu
Bitewe n'ubukomere bwayo bwinshi, imbaraga nyinshi, uburemere bwihariye bwihariye hamwe no guhangana na elastique, karbide ya boron ijyanye cyane cyane n’ibikoresho by’amasasu yoroheje, kandi ni ibikoresho byiza bitagira amasasu ku ndege, ibinyabiziga, ibirwanisho, umubiri w’umuntu n’ubundi burinzi.
4.Ibisabwa mu nganda za kirimbuzi
Borb karbide ifite igice kinini cyo kwinjiza neutron hamwe nigice kinini cyo kwinjiza neutron, kizwi ku rwego mpuzamahanga nkicyiza cya neutron cyiza mu nganda za kirimbuzi.Carbide ya Boron ifite umutungo ukungahaye, irwanya ruswa, itajegajega nziza yumuriro, nta isotopi ikora radiyo, ingufu za rayon nkeya, nibindi, bityo ikoreshwa cyane nkibikoresho byo kugenzura no gukingira ibikoresho bya reaction za kirimbuzi.Carbide ya Boron izakorwa mu nkoni ya karbide ya boron mu murima wa reaction ya kirimbuzi, kandi izanakorwa mu ifu ya karbide ya boron kubera ko bikenewe kongera ubuso.
