Kwicandelo lokhuseleko lwanamhlanje, ngokuphuculwa okuqhubekayo kwamandla ezixhobo, iimfuno zezinto ezithintela iimbumbulu ziya ziba nzima ngakumbi.I-silicon carbide, into ebonakala iqhelekile kodwa enamandla kakhulu, isanda kuvela njengeyona nto ithandwayo kushishino olungenazimbumbulu. Namhlanje, siza kutyhila isigqubuthelo esingaqondakaliyo se-silicon carbide bulletproof.
1, Ukutyhila umgaqo wokumelana neembumbulu
Eyona nto iphambili yokukhusela izixhobo kukusebenzisa amandla ee-projectile, ukuzicothisa isantya zide zilahlekelwe yingozi yazo. Izinto zesinyithi zemveli zixhomekeke kwi-deformation yeplastiki ukuze zifunxe amandla, ngelixa izinto ze-ceramic zifezekisa le njongo ngenkqubo eyahlukileyo yokutyumza encinci. Ukuthatha ii-ceramics ze-silicon carbide ezingenakuchukunyiswa ziibhulethi njengomzekelo, xa i-projectile ibetha, i-projectile iqala ukuba buthuntu ngoko nangoko kumphezulu we-impact, kwaye umphezulu we-ceramic uyatyumzwa ukuze wenze indawo eqinileyo eqhekekileyo. Le nkqubo ifana nokunika i-projectile "isando" kwaye ekuqaleni ifunxe amandla; Emva koko, i-projectile eqhekekileyo yaqhubeka isiya phambili, itshabalalisa indawo eqhekekileyo kwaye yenza umaleko oqhubekayo weziqwenga ze-ceramic; Ekugqibeleni, i-ceramic iyaphuka phantsi koxinzelelo lokuxinana, kwaye i-backplate iqala ukuwohloka. Amandla aseleyo afunxwa ngokupheleleyo kukuguqulwa kwezinto ze-backplate.
2, Kutheni i-silicon carbide inokuthi ingangenisi zinambuzane?
I-silicon carbide yi-compound eyenziwe kakhulu zii-covalent bonds, kwaye ii-Si-C bonds zayo zinokugcina amandla aphezulu kumaqondo obushushu aphezulu. Olu lwakhiwo lukhethekileyo lunika ii-silicon carbide ceramics iipropati ezininzi ezintle. Inobunzima obuphezulu kakhulu, ilandela idayimani, i-cubic boron nitride, kunye ne-boron carbide phakathi kwezinto eziqhelekileyo. Ifana nejoni elinxibe isikrweqe esiqinileyo, elikwaziyo ukumelana kakhulu nempembelelo ye-projectile; Kwangaxeshanye, inobunzima obuphantsi kwaye ilula xa yenziwe izixhobo ezikhusela iimbumbulu. Nokuba yeyemfazwe nganye okanye ixhotyiswe kwizithuthi nakwiinqwelomoya, ayizukuba ngumthwalo owongezelelweyo, kodwa endaweni yoko inokuphucula ukuhamba kweeyunithi zokulwa. Ukongeza, i-silicon carbide ikwanozinzo oluhle lobushushu kunye nokumelana nokugqwala kweekhemikhali, kwaye inokudlala indima yokumelana neembumbulu kwiindawo ezahlukeneyo ezinzima.
3, Iingenelo ezikhethekileyo ze-reaction sintered silicon carbide kwiindawo ezenziwe ngokwezifiso
Kwinkqubo yokulungiselela iiceramics ze-silicon carbide, i-reaction sintered silicon carbide (RBSiC) ivelele, ifanelekile ngakumbi kwimveliso yenxalenye eyenzelwe wena, ngenxa yezi zizathu zilandelayo:
1. Uxinano oluphezulu kunye namandla aphezulu: Phantsi kweemeko zobushushu obuphezulu, ikhabhoni ekhululekileyo isabela kunye ne-silicon engamanzi ukuvelisa iikristale ezintsha ze-silicon carbide. Kwangaxeshanye, i-silicon ekhululekileyo ingena ize izalise iimbobo, inyusa kakhulu uxinano lwento, iphantse isondele kuxinano lwethiyori. Oku akugcini nje ngokunika le nto amandla agqwesileyo okuxinzelela nokugoba, kodwa ikwayinika ukumelana okuhle nokuguguleka, okunokumelana noxinzelelo oluphezulu kunye neemeko eziphezulu zempembelelo, ukuhlangabezana neemfuno ezingqongqo zeendawo ezenzelwe wena ukuze uqine kwaye uhlale ixesha elide.
2. Ulwakhiwo olulawulwayo: Inkqubo yokukhupha i-reaction inokulawula ngokuchanekileyo ukukhula kweenkozo, yenze ulwakhiwo oluncinci nolufanayo. Olu lwakhiwo luncinci luphucula ngakumbi iipropati zoomatshini zezinto, luvumela ukuba zihlale zizinzile kwaye zingaqhekeki okanye zonakale xa zijongene noxinzelelo oluntsonkothileyo, nto leyo enika isiqinisekiso esiqinileyo sokuthembeka kweendawo ezenzelwe wena.
3. Ukuchaneka okuphezulu kobukhulu: Ngexesha lenkqubo yoxinano, utshintsho lobukhulu be-reaction sintered silicon carbide luncinci, nto leyo ibalulekileyo kwiindawo ezenzelwe wena. Nokuba yiplagi enye ye-soldier engangenisi bullet enemilo enzima okanye icandelo elikhethekileyo lokukhusela imoto elineemfuno zobukhulu obungqongqo, zinokwenziwa ngokuchanekileyo ukuqinisekisa ukuhambelana ngokugqibeleleyo nezixhobo.
4. Uzinzo oluhle lweekhemikhali: I-silicon carbide exutywe ne-reaction ayinazo iimbobo ezivulekileyo, nto leyo eyenza kube nzima ukuba i-oksijini kunye nezinto ezirhabaxa zingene ngaphakathi kwezinto, ngaloo ndlela zinokumelana ne-oxidation enamandla kakhulu kunye nokumelana nokugqwala. Oku kuthetha ukuba iimveliso ze-silicon carbide ezenziwe ngokwezifiso zisenokuhlala zisebenza ngokuzinzileyo, zandise ubomi benkonzo, kwaye zinciphise iindleko zokugcinwa kwiindawo zendalo okanye zeekhemikhali ezinzima ixesha elide.
4, intsimi yesicelo se-silicon carbide engangenisi zinambuzane
Ngenxa yokusebenza kwayo okugqwesileyo, izixhobo ze-silicon carbide ezikhusela iimbumbulu zisetyenziswe kakhulu kwiindawo ezininzi:
