N'ihe banyere nchebe nke oge a, na-aga n'ihu na-emewanyewanye ike nke ngwa agha, ihe ndị a chọrọ maka ihe ndị na-egbochi mgbọ na-aghọwanye ndị siri ike.Silicon carbide, ihe dị ka ihe nkịtị ma dị ike nke ukwuu, na-eji nwayọọ nwayọọ na-apụta dị ka ọkacha mmasị ọhụrụ na ụlọ ọrụ na-egbochi mgbọ. Taa, anyị ga-ekpughere ihe omimi mkpuchi nke silicon carbide bulletproof.
1. Ikpughe ụkpụrụ nke bulletproof
Isi ihe na-echebe ngwa agha bụ iri ike nke projectiles, na-ebelata ha ruo mgbe ihe ize ndụ ha tụfuru. Ngwa ọla ọdịnala na-adabere na nrụrụ rọba iji nweta ume, ebe ihe seramiiki na-enweta ihe mgbaru ọsọ a site na usoro mpịaji pụrụ iche. Inweta ceramics silicon carbide bulletproof dị ka ihe atụ, mgbe ihe na-emetụta ihe, projectile ahụ na-ebu ụzọ pụta ozugbo n'elu mmetụta ahụ, a na-agbajikwa elu seramiiki ka ọ bụrụ mpaghara gbajiri agbaji. Usoro a dị ka inye projectile “hama” ma na-etinye ike na mbụ; Mgbe ahụ, projectile ahụ na-agbaji agbaji gara n'ihu na-aga n'ihu, na-emebi ebe ahụ gbajiri agbaji ma na-akpụ akwa akwa seramiiki na-aga n'ihu; N'ikpeazụ, seramiiki gbajiri n'okpuru nrụgide tensile, na azụ azụ na-amalite imebi. A na-etinye ike fọdụrụnụ kpam kpam site na nrụrụ nke ihe ndabere azụ.
2. Gịnị mere silicon carbide nwere ike bulletproof?
Silicon carbide bụ ihe mejupụtara nke njikọta covalent, yana njikọ Si-C ya nwere ike idowe ike dị elu na oke okpomọkụ. Ihe owuwu a pụrụ iche na-enye ceramik silicon carbide nwere ọtụtụ ihe mara mma. O nwere isi ike dị oke elu, nke abụọ na diamond, cubic boron nitride, na boron carbide n'etiti ihe ndị a na-ahụkarị. Ọ dị ka dike nke yi uwe agha siri ike, nke nwere ike iguzogide mmetụta a na-atụ anya ya; N'otu oge ahụ, ọ nwere njupụta dị ala ma na-adị mfe karị ma ọ bụrụ na a na-eme ya ngwa ngwa. Ma ọ bụ maka ọgụ onye ọ bụla ma ọ bụ kwadebere na ụgbọ ala na ụgbọ elu, ọ gaghị abụ ibu ọzọ, kama ọ nwere ike imeziwanye mmegharị nke nkeji ọgụ. Na mgbakwunye, silicon carbide nwekwara ezigbo nkwụsi ike nke okpomọkụ yana nguzogide corrosion kemịkalụ, ma nwee ike rụọ ọrụ mgbochi nke mgbọ na gburugburu ebe dị mgbagwoju anya.
3, The pụrụ iche uru nke mmeghachi omume sintered silicon carbide na ahaziri akụkụ
N'ime usoro nkwadebe nke ceramics silicon carbide, mmeghachi omume sintered silicon carbide (RBSiC) pụtara, ọkachasị dabara maka mmepụta akụkụ ahaziri iche, maka ebumnuche ndị a:
1. Nnukwu njupụta na ike dị elu: N'okpuru ọnọdụ okpomọkụ dị elu, carbon free na-emeghachi na silicon mmiri mmiri iji mepụta kristal silicon carbide ọhụrụ. N'otu oge ahụ, silicon free permeates ma jupụta pores, na-amụba njupụta nke ihe onwunwe nke ukwuu, ọ fọrọ nke nta ka ọ bịaruo nso njupụta usoro iwu. Nke a ọ bụghị nanị na-enye ihe onwunwe ahụ nke ọma mkpakọ ma na-ehulata ike, ma na-enye ya dị mma na-eyi nguzogide, nke nwere ike iguzogide nrụgide dị elu na ọnọdụ mmetụta dị elu, na-ezute ihe siri ike nke akụkụ ndị ahaziri maka ike na ịdịte aka.
2. Microstructure na-achịkwa: Usoro mmeghachi omume mmeghachi omume nwere ike ịchịkwa uto nke ọka, na-emepụta obere microstructures dị obere na nke edo. Nke a dị mma microstructure na-eme ka ihe ndị na-emepụta ihe na-arụ ọrụ nke ọma dịkwuo mma, na-eme ka ọ nọgide na-eguzosi ike ma ghara ịdaba na mgbawa ma ọ bụ mmebi mgbe ọ na-eche nrụgide mgbagwoju anya dị iche iche ihu, na-enye nkwa siri ike maka ntụkwasị obi nke akụkụ ahaziri ahazi.
3. Oke akụkụ ziri ezi: N'oge densification usoro, akụkụ mgbanwe nke mmeghachi omume sintered silicon carbide dị ntakịrị, nke dị oké mkpa maka ahaziri akụkụ. Ma ọ bụ otu plọg na-egbochi mgbọ nwere ụdị dị mgbagwoju anya ma ọ bụ ihe nchekwa ụgbọ ala pụrụ iche nwere oke nha chọrọ, enwere ike rụpụta ya nke ọma iji hụ na ndakọrịta na akụrụngwa zuru oke.
4. Ezigbo nkwụsi ike kemịkalụ: mmeghachi omume sintered silicon carbide nwere ihe fọrọ nke nta ka ọ bụrụ oghere oghere, na-eme ka ọ sie ike ikuku oxygen na ihe ndị na-emebi emebi ịbanye n'ime ihe ahụ, si otú a na-enwe oke oxidation siri ike na nguzogide corrosion. Nke a pụtara na ngwaahịa mkpuchi mkpuchi silicon carbide ahaziri ka nwere ike ịnọgide na-arụ ọrụ kwụsiri ike, gbatịa ndụ ọrụ, ma belata ụgwọ mmezi na gburugburu eke ma ọ bụ kemịkalụ siri ike ruo ogologo oge.
4. Silicon carbide bulletproof ngwa ubi
Site na arụmọrụ ya mara mma, ejirila ihe mkpuchi mkpuchi silicon carbide mee ihe n'ọtụtụ mpaghara:
1. Akụrụngwa onye ọ bụla: silicon carbide bulletproof vest lining, mgbọ okpu agha, wdg, na-enye ndị agha ihe dị arọ na nchebe dị elu, na-enye ha ohere ịlụ ọgụ n'ọgbọ agha ka ha na-enwe nchebe nchebe a pụrụ ịdabere na ya.
2. Ụgbọ ala pụrụ iche: dị ka ụgbọ ala agha, ụgbọ ala na-ebufe ego, mgbochi iyi ọha egwu na ụgbọ ala na-achịkwa ọgba aghara, wdg, na-eji silicon carbide ceramic armor na akụkụ ndị dị mkpa, nke nwere ike iguzogide ọgụ dị iche iche nke ngwa agha ma chebe nchekwa nke ndị ọrụ na ihe ndị dị mkpa n'ime ụgbọ ahụ.
3. Aerospace: Silicon carbide bulletproof ihe na-eji ngwa agha helikopta na ụgbọ elu ndị ọzọ iji belata ibu nke ha, melite arụmọrụ ụgbọ elu, ma kwalite ikike ha ichebe ọkụ ndị iro, na-eme ka nchekwa ụgbọ elu dị elu.
Site na ọganihu teknụzụ na-aga n'ihu, silicon carbide bulletproof ihe ga-aga n'ihu na-azụlite ma na-emepụta ihe ọhụrụ, na-ewu usoro nchebe siri ike maka nchekwa nchekwa. Ọ bụrụ na ị nwere mmasị na akụkụ ahaziri nke mmeghachi omume sintered silicon carbide ceramics, biko nweere onwe gị ịkpọtụrụ anyị.
