Mu rwego rwo kurinda ibintu bigezweho, hamwe no gukomeza kunoza imbaraga z'intwaro, ibisabwa ku bikoresho bidashobora kwinjizwamo amasasu birarushaho gukomera.Karubide ya silikoni, ibikoresho bisa n'ibisanzwe ariko bifite imbaraga nyinshi, bigenda bihinduka ikintu gishya gikunzwe cyane mu nganda zirinda amasasu. Uyu munsi, turagaragaza igitambaro cy'amayobera cya silikoni irinda amasasu.
1, Gushyira ahagaragara ihame ryo kwirinda amasasu
Ishingiro ry'uburinzi bw'intwaro riri mu gukoresha ingufu z'ibisasu, bikagabanya umuvuduko kugeza igihe bitakaza ibyago byabyo. Ibikoresho gakondo by'icyuma byishingikiriza ku guhindagurika kwa pulasitiki kugira ngo bikurure ingufu, mu gihe ibikoresho bya ceramic bigeraho iyi ntego binyuze mu buryo budasanzwe bwo gusya. Dufashe urugero rwa silicon carbide idashobora gushwanyaguzwa n'amasasu ya kera, iyo projectile ikoze ku gikoresho, projectile ibanza kuba ishaje ako kanya ku buso bw'igisasu, maze ubuso bwa ceramic bugashwanyagurika kugira ngo bukore agace gakomeye kacitsemo ibice. Ubu buryo ni nko guha projectile "inyundo" kandi itangira gukurura ingufu; Hanyuma, projectile icitsemo ibice yakomeje kujya imbere, irangiza agace kacitsemo ibice maze ikora urwego ruhoraho rw'ibisasu bya kera; Amaherezo, ceramic iravunika munsi y'imbaraga zo gukurura, maze inyuma hagatangira kwangirika. Ingufu zisigaye zitwarwa burundu n'ihindagurika ry'ibikoresho bya nyuma.
2, Kuki karubide ya silikoni ishobora kwirinda amasasu?
Karubide ya silikoni ni ikintu kigizwe ahanini n'imigozi ya covalent, kandi imigozi yayo ya Si-C ishobora kugumana imbaraga nyinshi mu bushyuhe bwinshi. Iyi miterere idasanzwe itanga imiterere myiza ya silikoni ya silikoni. Ifite ubukana bwinshi cyane, ikaba iya kabiri nyuma ya diyama, nitride ya cubic boron, na karubide ya boroni mu bikoresho bisanzwe. Ni nk'umurwanyi wambaye intwaro ikomeye, ushobora kurwanya cyane impanuka; Muri icyo gihe, ifite ubucucike buke kandi irushaho kuba yoroshye iyo ikozwemo ibikoresho bidashobora kwinjizwamo amasasu. Byaba ari ibyo kurwana ku giti cye cyangwa ibikoresho biri ku modoka n'indege, ntabwo izaba umutwaro w'inyongera, ahubwo ishobora kunoza uburyo imitwe y'imirwano igenda. Byongeye kandi, karubide ya silikoni ifite ubushyuhe bwiza kandi irwanya ingese, kandi ishobora kugira uruhare rudahindagurika mu bidukikije bitandukanye bigoye.
3, Ibyiza byihariye bya karubide ya silikoni ikoze mu buryo bwa "reaction sintered" mu bice byayo
Mu gutegura ibumba rya silicon carbide, silicon carbide ikoreshwa mu gukora ibintu bitandukanye (RBSiC) iragaragara cyane, cyane cyane ikwiriye gukorwa mu bice byayo, kubera impamvu zikurikira:
1. Ubucucike bwinshi n'imbaraga nyinshi: Mu gihe cy'ubushyuhe bwinshi, karuboni yigenga ikorana na silikoni y'amazi kugira ngo ikore kristu nshya za silikoni. Muri icyo gihe, silikoni yigenga iranjira kandi yuzura imyenge, yongera cyane ubucucike bw'ibikoresho, hafi ya byose bihuye n'ubucucike bw'ibitekerezo. Ibi ntibiha gusa ibikoresho imbaraga nziza zo gukanda no kunama, ahubwo binabiha ubushobozi bwo kudashira, bushobora kwihanganira umuvuduko mwinshi n'ibihe bikomeye, bugahura n'ibisabwa bikomeye by'ibice byihariye kugira ngo bikomere kandi birambe.
2. Imiterere mito igenzurwa: Uburyo bwo gutwika ibintu bushobora kugenzura neza imikurire y'ibinyampeke, bugakora imiterere mito kandi isa. Iyi miterere mito irushaho kongera imiterere y'ibikoresho, bigatuma bigumana ihamye kandi bidakunze kwangirika cyangwa kwangirika iyo bihuye n'imihangayiko itandukanye, bitanga icyizere gikomeye cy'uko ibice byagenwe byizewe.
3. Ubuziranenge bwo hejuru: Mu gihe cyo gukurura ibintu, impinduka mu bipimo bya karubide ya silikoni ikoreshwa mu gukora ibintu ni nkeya, ibyo bikaba ari ingenzi ku bice byihariye. Byaba ari agasanduku kamwe k’igisirikare karinda amasasu gafite imiterere igoye cyangwa igice cyihariye cyo kurinda imodoka gifite ingano ikomeye, bishobora gukorwa neza kugira ngo bihuzwe neza n’ibikoresho.
4. Gukomera neza mu mikorere y’ibinyabutabire: Karubide ya silikoni ikozwe muri Reaction sintered ntabwo ifite utwenge dufunguye, bigatuma ogisijeni n’ibintu byangiza bidashobora kwinjira imbere mu bikoresho, bityo bikaba bifite ogisijeni ikomeye cyane kandi birwanya ingese. Ibi bivuze ko ibikoresho bya silikoni byifashishwa mu gukora neza bishobora gukomeza gukora neza, kongera igihe cyo gukora, no kugabanya ikiguzi cyo kubungabunga ahantu habi cyangwa mu binyabutabire mu gihe kirekire.
4, aho gukoresha karubide ya silikoni idashobora gutwikirwa n'amasasu
Bitewe n'imikorere myiza cyane, ibikoresho bya silikoni karubide bidakoresha amasasu byakoreshejwe cyane mu nzego nyinshi:
1. Ibikoresho byihariye: umwenda urinda amasasu wa silikoni, ingofero idakingira amasasu, nibindi, biha abasirikare uburinzi bworoshye kandi buhagije, bubafasha kurwana ku rugamba mu buryo bworoshye kandi bafite uburinzi bwizewe.
2. Imodoka zidasanzwe: nk'imodoka zifite intwaro, imodoka zitwara amafaranga, izirwanya iterabwoba n'izishinzwe kurwanya imyivumbagatanyo, n'ibindi, zifite intwaro za silicon carbide ceramic mu bice by'ingenzi, zishobora kurwanya neza ibitero bitandukanye by'intwaro no kurinda umutekano w'abakozi n'ibikoresho by'ingenzi biri mu modoka.
3. Ibyerekeye ikirere: Ibikoresho bidapfa kwibasirwa n'amasasu bya silikoni bikoreshwa kuri kajugujugu n'izindi ndege zifite intwaro kugira ngo bigabanye uburemere bwazo, binoze imikorere y'indege, kandi binongere ubushobozi bwazo bwo kwirinda inkongi z'umwanzi, bigamije umutekano mu ndege.
Bitewe n'iterambere rihoraho ry'ikoranabuhanga, ibikoresho bidashobora kwangirika mu ikoranabuhanga rya silicon carbide bizakomeza gutera imbere no guhanga udushya, byubaka umurongo ukomeye w'ubwirinzi kugira ngo birinde umutekano. Niba ushishikajwe n'ibice byihariye bya silicon carbide ceramics, nyamuneka twandikire.
