N'ihe gbasara nchekwa nke oge a, site na mmụba na-aga n'ihu na ike ngwa agha, ihe achọrọ maka ihe ndị na-egbochi mgbọ na-aghọwanye ihe siri ike.Silicon carbide, ihe dị ka ihe nkịtị mana nke na-enye ike dị ukwuu, na-apụta nwayọọ nwayọọ dị ka ihe ọhụrụ a na-ahụkarị n'ụlọ ọrụ na-egbochi mgbọ. Taa, anyị ga-ekpughe ihe mkpuchi dị omimi nke silicon carbide bulletproof.
1, Ikpughe ụkpụrụ mgbochi mgbọ
Isi ihe dị mkpa maka nchekwa ngwa agha bụ iri ike nke ihe mgbochi, na-ebelata ha ruo mgbe ha ga-efunahụ ihe ize ndụ ha. Ihe ndị e ji ígwè eme ihe ọdịnala na-adabere na mgbanwe plastik iji nara ike, ebe ihe ndị e ji ígwè seramiiki eme ihe na-emezu ihe mgbaru ọsọ a site na usoro obere igwe e ji agbaji ihe. Site n'iji ihe mkpuchi silicon carbide dịka ihe atụ, mgbe ihe mgbochi metụtara, ihe mgbochi na-ebu ụzọ na-akpụ akpụ ozugbo n'elu ihe mmetụta ahụ, a na-akụrikwa elu seramiiki ahụ ka ọ bụrụ ebe siri ike gbawara agbawa. Usoro a dị ka inye ihe mgbochi "hammer" ma na-amịkọrọ ike na mbụ; Mgbe ahụ, ihe mgbochi ahụ gbawara agbawa gara n'ihu na-aga n'ihu, na-emebi mpaghara ahụ gbawara agbawa ma na-emepụta oyi akwa nke iberibe seramiiki na-aga n'ihu; N'ikpeazụ, mgbawa seramiiki n'okpuru nrụgide nrụgide, ihe mgbochi ahụ na-amalitekwa ịgbawa agbawa. Ike fọdụrụnụ na-abanye kpamkpam site na mgbanwe nke ihe mkpuchi azụ.
2, Gịnị mere silicon carbide ji bụrụ ihe na-egbochi mgbọ?
Silicon carbide bụ ihe mejupụtara ya nke bụ covalent bonds, njikọ Si-C ya nwere ike ịnọgide na-enwe ike dị elu na okpomọkụ dị elu. Nhazi pụrụ iche a na-enye seramiiki silicon carbide nwere ọtụtụ ihe onwunwe dị mma. O nwere ike dị oke elu, nke abụọ karịa dayamọnd, cubic boron nitride, na boron carbide n'etiti ihe ndị a na-ahụkarị. Ọ dị ka onye agha yi uwe agha siri ike, nke nwere ike iguzogide mmetụta projectile siri ike; N'otu oge ahụ, ọ nwere obere njupụta ma dị mfe ibu mgbe e mere ya ka ọ bụrụ ngwa agha na-egbochi mgbọ. Ma ọ bụ maka ọgụ nkeonwe ma ọ bụ ihe eji arụ ọrụ n'ụgbọala na ụgbọelu, ọ gaghị abụ ibu ọzọ, kama ọ nwere ike ime ka mmegharị nke ngwa agha ka mma. Na mgbakwunye, silicon carbide nwekwara ezigbo nkwụsi ike okpomọkụ na iguzogide corrosion kemịkalụ, ọ nwekwara ike ịrụ ọrụ siri ike na gburugburu ebe dị iche iche dị mgbagwoju anya.
3, Uru pụrụ iche nke mmeghachi omume sintered silicon carbide na akụkụ ahaziri ahazi
N'ime usoro nkwadebe nke seramiiki silicon carbide, mmeghachi omume sintered silicon carbide (RBSiC) pụtara ìhè, nke dabara adaba karịsịa maka mmepụta akụkụ ahaziri ahazi, maka ihe ndị a:
1. Oke njupụta na ike dị elu: N'ọnọdụ okpomọkụ dị elu, carbon efu na-emeghachi omume na silicon mmiri mmiri iji mepụta kristal silicon carbide ọhụrụ. N'otu oge ahụ, silicon efu na-abanye ma na-ejupụta oghere ndị ahụ, na-eme ka njupụta nke ihe ahụ dịkwuo elu nke ukwuu, na-eru nso njupụta echiche. Nke a abụghị naanị na ọ na-enye ihe ahụ ike nrụgide na ịgbagọ agbagọ dị mma, kamakwa ọ na-enye ya ezigbo nguzogide iyi, nke nwere ike iguzogide nrụgide dị elu na ọnọdụ mmetụta dị elu, na-emezu ihe achọrọ siri ike nke akụkụ ahaziri maka ike na ịdịte aka.
2. Ọdịdị obere ihe a na-achịkwa: Usoro nhazi mmeghachi omume nwere ike ijikwa uto nke ọka, na-emepụta obere ihe owuwu dị iche iche na otu. Ọdịdị obere ihe owuwu a na-eme ka ihe owuwu ahụ dịkwuo mma, na-eme ka ọ kwụsie ike ma ghara ịdị mfe ịgbawa ma ọ bụ mebie mgbe ọ na-eche nrụgide dị iche iche ihu, na-enye nkwa siri ike maka ntụkwasị obi nke akụkụ ahaziri ahazi.
3. Izi ezi dị elu: N'oge usoro njupụta, mgbanwe nha nke silikọn carbide mmeghachi omume dị obere, nke dị oke mkpa maka akụkụ ahaziri ahazi. Ma ọ bụ otu plọg na-enweghị mgbọ agha nwere ọdịdị dị mgbagwoju anya ma ọ bụ ihe nchekwa ụgbọala pụrụ iche nke nwere nha siri ike, enwere ike imepụta ha kpọmkwem iji hụ na ha dabara nke ọma na akụrụngwa.
4. Ezigbo nkwụsi ike kemịkalụ: carbide silicon nke a na-eme ka ọ ghara inwe oghere mepere emepe, nke na-eme ka o siere oxygen na ihe ndị na-emebi emebi ike ịbanye n'ime ihe ahụ, si otú a na-enwe oke ike oxidation na corrosion. Nke a pụtara na ngwaahịa silicon carbide ahaziri ahazi ka nwere ike ịnọgide na-arụ ọrụ kwụsiri ike, na-agbatị ndụ ọrụ, ma belata ọnụ ahịa mmezi na gburugburu ebe obibi siri ike ma ọ bụ kemịkalụ ruo ogologo oge.
4, Silicon carbide bulletproof ngwa ubi
Site na arụmọrụ ya dị oke mma, a na-eji ihe mkpuchi silicon carbide eme ihe n'ọtụtụ ebe:
1. Ngwa nkeonwe: mkpuchi vest silicon carbide nke nwere ike igbochi mgbọ, okpu agha na-anaghị agba mgbọ, wdg., na-enye ndị agha nchekwa dị mfe ma dị elu, na-enye ha ohere ịlụ ọgụ n'ọgbọ agha n'agbanyeghị na ha nwere nchekwa nchekwa a pụrụ ịdabere na ya.
2. Ụgbọala pụrụ iche: dịka ụgbọala agha, ụgbọala mbupu ego, ụgbọala mgbochi iyi ọha egwu na ụgbọala njikwa ọgba aghara, wdg., nwere ihe agha seramiiki silicon carbide n'akụkụ dị mkpa, nke nwere ike iguzogide mwakpo ngwa ọgụ dị iche iche nke ọma ma chebe nchekwa nke ndị ọrụ na ihe dị mkpa dị n'ime ụgbọ ala ahụ.
3. Ụgbọelu: A na-eji ihe ndị na-anaghị agba ọsọ ígwè silicon carbide eme ihe na helikọpta ndị agha na ụgbọelu ndị ọzọ iji belata ibu ha, melite arụmọrụ ụgbọelu, ma melite ikike ha ichebe onwe ha pụọ na ọkụ ndị iro, na-ahụ na nchekwa ụgbọelu.
Site na ọganihu teknụzụ na-aga n'ihu, ihe ndị na-egbochi mgbọ silicon carbide ga-anọgide na-emepụta ma na-emepụta ihe ọhụrụ, na-ewulite ahịrị nchebe siri ike maka nchekwa. Ọ bụrụ na ị nwere mmasị na akụkụ pụrụ iche nke seramiiki silicon carbide sintered reaction, biko nweere onwe gị ịkpọtụrụ anyị.
