I-Nickel Titanium Alloy iPulverized

Ingxubevange ye-nickel-titanium

I-alloy ye-binary ye-nickel kunye ne-titan, okanye i-nitinol (okanye i-nitinol), yaziwa ngokuba yi "alloy memory alloy". Iialloyi zeenkumbulo zemilo ziialloyi ezikhethekileyo ezibuyisela ngokuzenzekelayo i-deformation yazo yeplastiki kwimilo yoqobo xa ishushu. Inezinga eliphezulu lokwandiswa kwe-20%. Ubomi bayo bokudinwa bumalunga ne-1*107. Inepropathi yokumanzisa ngokuphindwe ka-10 kunemithombo eqhelekileyo. Iyakwazi ukumelana nomhlwa kunentsimbi yezonyango. Oku kuyenza ibe yimathiriyeli eguquguqukayo enokusebenzela uninzi lobunjineli kunye nezicelo zonyango.

Umsebenzi wememori ye-memory alloy ayikuphela kwento eyenza ukuba ibe yodwa. Ngaphandle kokunganyangeki kwayo, ukumelana nokugqwala, ukuqina kwe-superelasticity, kunye nokumanzisa okuphezulu kukwagqwesile.

Utshintsho oluxhomekeke kwiqondo lokushisa kunye nokutshintsha koxinzelelo lomatshini kunokubangela izigaba ezimbini zekristale kwi-Nitinol alloy, i-austenite kunye ne-martensite. Ulandelelwano lwenguqu yesigaba se-Nitinol ye-alloy yile: isigaba se-austenite njengomzali, emva koko ngu-R kwaye ekugqibeleni i-martensite. Ukuba isigaba se-R si-rhomboid ke i-austenite kumaqondo aphezulu aphezulu (enkulu kunokulingana: iqondo lokushisa i-austenite yaqala), okanye emva kokuba umthwalo ususiwe yi-cube. Le milo izinzile kakhulu. Izigaba zeMartensite ziphantsi kakhulu kwiqondo lokushisa, ngaphantsi kwe-Mf, okanye xa ukulayisha kwenziwa ngaphandle. Ziyakwazi ukuba ne-hexagonal kunye ne-ductile.

IiPropati zeMzimba zeNickel Titanium Alloy Powder

1) Imemori yokwakheka. 1. Inkumbulo yokwakheka. Xa isigaba somzali sifudunyezwa ngaphantsi kwe-Mf ukudala i-martensite ukusuka kwimilo ethile, ifakwe ngaphantsi kwe-Af ukwenza i-martensite. Ukuguqulwa kwesigaba sokubuyela umva kuvumela ukuba izinto eziphathekayo zibuyisele ngokuzenzekelayo imilo yayo yokuqala. Ngokwenyani, inkumbulo yokuma lutshintsho lwesigaba esisebenzayo kwiNitinol.

2) I-Superelasticity. 2) I-Superelasticity. Umboniso unokuba noxinzelelo olukhulu kunomda weelastiki xa uphantsi kwamandla angaphandle. Ubunzima bunokufunyanwa lula ngokukhulula. Utshintsho lwe-martensitic olubangelwa uxinzelelo lwenzeka kwizinto zomzali kwaye lubangela utshintsho kwindlela yokuziphatha koomatshini. Umthetho weHooke awusebenzi kule alloy, njengoko umda wayo we-elastic uphezulu kakhulu kunezinto eziqhelekileyo. I-Superelasticity ayichatshazelwa ngamandla ashushu, ngokungafaniyo neempawu zememori yemo. I-Hyperelasticity, ngamanye amazwi, ithetha ukuba uxinzelelo alunyuswanga ngokunyuka koxinzelelo phezu koluhlu lwe-deformations. Unokwahlula i-hyperelasticity kwi-nonlinear kunye ne-linear hyperelasticity. Phantse ubudlelwane bomgca bukhona phakathi koxinzelelo kunye noxinzelelo kwigrafu yakudala yoxinzelelo. I-Hyperelasticity engabonakaliyo ibhekisela kuphela kwi-martensitic eyenziwe ngoxinzelelo kunye nokuguqulwa kwayo okungafaniyo okwenzeka ngexesha lokulayisha / ukukhulula iinkqubo. Ikwabizwa ngokuba yi-pseudo-elasticity phase transformation. I-Nitinol alloy ine-pseudo-elasticity malunga ne-8%. Unokutshintsha iimeko zonyango lobushushu ukuze uguqule ukuqina kweNitinol. Ukuba iimeko zonyango lokushisa zitshintshwa zibe yi-400C, ngoko i-superelasticity iya kuncipha.

(3) Ukuvakalelwa kobushushu bomlomo. Ubushushu bomlomo alunampembelelo kwintsimbi yentsimbi okanye iCoCr alloy tooth orthotic wire force. Ukwahluka kwiqondo lokushisa kuchaphazela amandla e-orthodontic ye-superelastic Nitinol orthodonticwire. Ukuba izinga lokuguqulwa lihlala lihlala, liya kuba lincinci. Xa iqondo lobushushu linyuka, i-orthodontic force iyanda. Isixhobo sinokuvuselela ukujikeleza kwegazi kwiindawo apho kukho ukudodobala kwegazi. Kuya kukhawulezisa ukuhamba kwamazinyo. I-Orthodontist, nangona kunjalo, ayikwazi ukulinganisa ngokuchanekileyo kunye nokulawula amandla okulungisa kwindawo yomlomo.

4)Ukumelana nokubola. Uphando lubonise ukuba ukuxhathisa kwe-nickel-titanium kwi-corrosion ye-corrosion wire kuthelekiswa nocingo olungenasici.

5) Ukuxhathisa ubuthi: I-nickel titanium shape memory alloy imalunga ne-50% nickel. I-Nickel yaziwa ngokubangela iziphumo ze-carcinogenic kunye nokukhuthaza umhlaza. Ngenxa yokuba i-alloy ye-Ni-Ti ine-biocompatibility efanelekileyo, isebenza njengomqobo ngokufaka i-oxidizing umaleko we-titanium. I-Ni inokuthintelwa nguTiXOy/TixNiOy kumphezulu womaleko.

6) I-soft orthodontic force. I-cobalt i-chrome-nickel wire, i-cobalt chrome-nickel wire, i-nickel-chromium alloywire, i-Australian alloywire, i-golide yegolide, kunye ne-soft orthodontic force yimizekelo yeengcingo zamazinyo ezifumanekayo ngokurhweba. I-curves-displacement curves yala macingo yavavanywa phantsi kwe-tensile kunye neemeko ezigobileyo ezintathu. Iqonga lokukhulula i-Nitinol lelona lisezantsi- kunye nelona lithe tyaba. Ibonisa ukuba i-Nitinol ibonelela ngeyona nto ilungileyo kunye neyona nto ilungileyo yokulungisa amandla.

7) Ukufunxeka kakuhle kukothuka Isixhobo sokufunxa esilungileyo sibalulekile. Iziphumo zophononongo zibonise ukuba ii-archwire wire vibrations zinkulu kunezo ze-hyperelastic ni-titanium silk kunye ne-super-elastic ni-titanium arwire. Iamplitude yokuqala yokungcangcazela yocingo lwentsimbi ye-archwire yayisisiqingatha sobukhulu socingo olungenasici. Ukungcangcazela okuhle kunye neempawu zokufunxa ukothuka kwe-archwire zibalulekile kwimpilo kunye nentlalontle yamazinyo. Iingcingo zemveli, ezifana nentsimbi engenasici, zinokunyusa ukufunxwa kweengcambu.
