I-Titanium iyaphumelela xa imeko-bume iqulethe ii-chloride okanye amanzi olwandle apho imingxuma yentsimbi engagqwaliyo engama-316/316L. Umaleko we-TiO2 ongasebenziyo uzinzile kwezi meko, ngoko ke amanqanaba e-titanium aphatha inkonzo yolwandle kunye neyekhemikhali eya kuhlasela kancinci i-stainless. I-Titanium iphumelela ngobunzima: malunga ne-4.5 g/cm3 xa ithelekiswa ne-8.0 g/cm3 kwi-stainless ye-austenitic, inxalenye ye-titanium ilula malunga ne-45%.
Intsimbi engagqwaliyo iphumelela ngokwexabiso, ukufumaneka kwayo, kunye nokuqina kwayo ngokupheleleyo. I-316/316L ixabisa kancinci ngekhilogram nganye, ifumaneka kwisitokhwe, kwaye iqinile ngakumbi (i-modulus ephezulu). Kwinkonzo yokugqwala ephakathi kunye nemida yebhajethi okanye yexesha lokuqalisa, intsimbi engagqwaliyo ye-316L idla ngokuba lukhetho olusebenzayo.
Indlela elungeleleneyo: kwinkonzo ye-chloride okanye yeekhemikhali enzima, vavanya i-titanium yeBanga lesi-2; kwinkonzo ephakathi, vavanya intsimbi engagqwaliyo engama-316/316L kunye nexabiso layo eliphantsi. I-LIANYUNGANG DAPU METAL ibonelela ngeemveliso zentsimbi engagqwali ezingama-316 kunye nemibhobho yentsimbi engagqwaliyo , ukuze sikwazi ukuxhasa nayiphi na into efunekayo kwisicelo sakho. Ukuba ulinganisa i-titanium ngokuchasene ne-stainless, uthelekiso lwethu lwe-titanium kunye nentsimbi engagqwali luhamba kulo lonke urhwebo.
Imibuzo ebuzwa qho
Zithini iiklasi ze-titanium?
Iindidi eziphambili zetitanium yi-1, 2, 3, kunye ne-4 (ecocekileyo ngokwezorhwebo) kunye ne-5, 7, 9, 12, kunye ne-23 (ii-alloys). Iindidi 1-4 zahlukile ngokomxholo weoksijini kunye nesinyithi; iindidi 5 nangaphezulu zongeza izinto zokudibanisa ngabom ukuze zisetyenziswe ngamandla, ukugqwala, okanye kwezonyango.
Ngowuphi umgangatho we-titanium oqinileyo?
Ibanga lesi-5 (Ti-6Al-4V) linamandla aphezulu kwiibanga eziqhelekileyo, kwaye ubuncinci amandla okutsalwa ayi-895 MPa. Phakathi kweebanga ezicocekileyo zorhwebo, iBanga lesi-4 lolona lomeleleyo kwi-550 MPa.
Ngowuphi umgangatho we-titanium ofanelekileyo kwi-corrosion?
Ibanga lesi-7 libonelela ngokumelana nokugqwala okungcono kakhulu kuba ukongezwa kwayo kwe-palladium kukhusela ekunciphiseni ii-asidi kunye nokugqwala kwe-crevice. Kwinkonzo yamanzi olwandle kunye ne-chloride ngokubanzi, iBanga lesi-2 likhetho eliqhelekileyo.
Uthini umahluko phakathi kweBanga lesi-1 neBanga lesi-2 letitanium?
Ibanga loku-1 lineoksijini ephantsi (0.18% ubuninzi), nto leyo eyenza ukuba lithambe kwaye libe nomtsalane ngakumbi xa linamandla okutsalwa angama-240 MPa. Ibanga lesi-2 lineoksijini ephezulu engama-0.25%, nto leyo esinika amandla aphezulu (345 MPa) ngelixa lihlala lilungele ukwakheka. Ibanga lesi-2 lelona lisetyenziswa kakhulu kwezi zimbini.
Yeyiphi iklasi ye-titanium esetyenziselwa ukufakelwa kwezonyango?
Ibanga lama-23 (Ti-6Al-4V ELI) lisemgangathweni wee-implants ezithwala umthwalo ngokwe-ASTM F136. Ibanga lesi-4 le-CP lisetyenziselwa ezinye izixhobo zotyando, kwaye iBanga lesi-2 le-CP kwii-implants ezithwala umthwalo kunye nezixhobo ezinokuphinda zisetyenziswe.
Ingaba i-titanium yeBanga lesi-9 inamandla kune-Grade 5?
Inombolo yeBanga lesi-9 (Ti-3Al-2.5V) inamandla okutsalwa amalunga ne-620 MPa, ngaphantsi kakhulu kweBanga lesi-5 le-895 MPa. Inzuzo yeBanga lesi-9 kukuba ikwazi ukwakheka kakuhle nokubanda kunye nokudityaniswa, hayi amandla aphezulu.
Ngowuphi umgangatho we-titanium ofanelekileyo kwi-machining?
Ibanga lesi-2 liqhele ukuba lula ukulisebenzisa ngomatshini kwaye alibizi kakhulu ukulisebenzisa, nangona lidla ngokungcolisa inyongo. Oomatshini bebanga lesi-5 badla ngokuguguleka kakhulu kwezixhobo kwaye baqina umsebenzi. Ibanga lama-23 lelona libiza kakhulu kumatshini ngenxa yeendleko zalo eziphezulu kunye neemfuno zolawulo lwenkqubo.
isiphelo
Ukufunda itshati yebanga le-titanium kufikelela kwingcamango enye: amabakala 1-4 zizinto ze-CP eziqhutywa ngumhlwa ezahluka ngokweoksijini nesinyithi, kwaye amabakala 5 nangaphezulu zi-alloys eziqhutywa ngamandla ezongeza izinto ezilawulwayo. Ibanga 2 lihashe eliqhelekileyo le-CP, iBanga 5 li-alloy enamandla aphezulu, kwaye iBanga 23 likhonza izinto zokufakelwa kwezonyango ezithwala umthwalo. Xa ungaqinisekanga, fanisa ibakala nomda wakho ophambili endaweni yegama elivakala linamandla.
