Koj puas tau hnov dua txog titanium screws?
Kuv paub zoo txog cov ntsia hlau titanium. Lawv tsis yog cov khoom siv txuas ib txwm, tab sis sawv cev rau qhov kev nrhiav qhov kawg ntawm kev sib dua, lub zog, kev tiv thaiv corrosion, thiab kev ntseeg tau hauv kev tsim khoom siab.
Cov yam ntxwv zoo ntawm titanium screws
1. Lub zog tshwj xeeb siab heev: Qhov no yog nws qhov zoo tseem ceeb. Lub zog ntawm cov hlau titanium (xws li TC4 feem ntau) zoo ib yam li cov hlau muaj zog siab, tab sis lawv qhov ceev (kwv yees li 4.51g / cm ³) tsuas yog 60% ntawm cov hlau. Qhov no txhais tau tias cov ntsia hlau titanium tuaj yeem ua tiav qhov hnyav tseem ceeb ntawm tib lub zog.
2. Kev tiv thaiv xeb zoo heev: Qhov saum npoo ntawm cov ntsia hlau titanium tsim cov zaj duab xis oxide ntom thiab ruaj khov, uas ua rau lawv tiv taus xeb los ntawm huab cua, dej hiav txwv, chloride ions, thiab ntau yam tshuaj lom neeg, nrog lub neej ntev dua li cov hlau tsis xeb.
3. Kev sib haum xeeb zoo heev: Titanium ntshiab (xws li TA1, TA2) thiab qee cov titanium alloys tsis muaj tshuaj lom, tsis ua rau ua xua rau tib neeg cov nqaij, thiab yuav tsis raug cov kua dej hauv lub cev corroded, ua rau lawv yog cov khoom siv zoo tshaj plaws rau kev phais mob (xws li cov phaj pob txha thiab cov ntsia hlau).
4. Kev tiv taus kub dav: Titanium ntsia hlau tuaj yeem tswj tau cov khoom siv kho tshuab zoo hauv qhov kub dav ntawm -250 ℃ txog 600 ℃, tsis muaj qhov kub qis embrittlement zoo li hlau, thiab tuaj yeem tswj tau lub zog ntawm qhov kub nruab nrab.
Cov cheeb tsam tseem ceeb ntawm daim ntawv thov titanium ntsia hlau
Aerospace: Qhov no yog qhov chaw siv thawj zaug thiab tseem ceeb tshaj plaws ntawm titanium screws. Yuav kom txo tau txhua gram ntawm qhov hnyav thiab tswj kev ntseeg tau hauv qhov chaw ib puag ncig hnyav, titanium screws yog qhov tseem ceeb los ntawm cov tawv nqaij dav hlau, cov thav duab qauv mus rau lub cav. Nws muaj peev xwm ze rau cov khoom siv carbon fiber composite, uas tuaj yeem zam qhov teeb meem ntawm galvanic corrosion.
Kev kho mob siab kawg: siv los tsim cov ntsia hlau rau kev txhim kho cov khoom cog rau hauv tib neeg lub cev, nrog rau cov cuab yeej phais siab kawg. Nws cov biocompatibility thiab corrosion tsis kam ua kom muaj kev nyab xeeb mus sij hawm ntev.
Cov khoom siv sib tw thiab cov khoom siv kis las siab: F1 sib tw tsheb, tsheb kauj vab sab saum toj, tsheb kauj vab sib tw, thiab lwm yam, nrog rau qhov yuav tsum tau hnyav thiab lub zog, titanium screws yog cov qauv txheem.
Kev Tsim Kho Tshuaj Lom Zem thiab Dej Hiav Txwv: Siv rau hauv cov chaw muaj zog corrosive xws li reactors hauv cov nroj tsuag tshuaj, cov chaw roj av hauv hiav txwv, nkoj, thiab lwm yam.
Cov khoom siv hluav taws xob thiab cov khoom siv thaij duab: Qee cov khoom lag luam siab siv cov ntsia hlau titanium los qhia lawv qhov zoo thiab ua tiav cov qauv meej.
Vim li cas ho muaj teeb meem tsim khoom thiab cov nqi siab
Cov lus 'ib lub ntsia hlau me me muag rau ntau dua ib puas yuan' uas koj tau nug ua ntej yog los ntawm qhov no.
Tus nqi khoom siv raw siab: Cov txheej txheem smelting ntawm titanium yog qhov nyuaj thiab siv zog ntau heev, ua rau tus nqi siab rau cov ntaub ntawv raw titanium thiab titanium alloy lawv tus kheej.
Nyuaj rau tshuab: Titanium alloy yog ib qho khoom siv nyuaj rau tshuab, nrog rau kev ua haujlwm thermal tsis zoo thiab muaj zog sib raug zoo, uas tuaj yeem ua rau cov cuab yeej hnav hnyav, ua haujlwm tawv, cuab yeej lo, thiab lwm yam teeb meem. Tshwj xeeb tshaj yog hauv kev ua cov xov, nws yooj yim heev ua rau lub qhov dej tawg.
Kev tswj xyuas zoo nruj: Hauv kev lag luam aerospace thiab kev kho mob, txhua lub ntsia hlau yuav tsum tau kuaj xyuas tsis puas tsuaj, kev tshuaj xyuas metallographic, kev sim ua haujlwm kho tshuab, thiab lwm yam, uas muaj daim ntawv pov thawj siab heev thiab cov nqi kuaj.
Yuav xaiv li cas titanium ntsia hlau?
Thaum xaiv cov titanium screws, cov ntsiab lus tseem ceeb hauv qab no yuav tsum tau xav txog:
1. Qib khoom siv:
Titanium ntshiab (TA1, TA2): muaj qhov zoo tshaj plaws corrosion tsis kam thiab qis zog, feem ntau yog siv rau tshuaj lom neeg thiab kev cog hniav kho mob.
TC4 (Ti-6Al-4V): Cov hlau titanium muaj zog heev uas siv ntau tshaj plaws nrog cov khoom zoo heev, siv rau hauv kev lag luam aerospace thiab kev lag luam dav dav.
TB3, TB4 (β-hom titanium alloy): Lub zog siab dua tab sis qis dua me ntsis kev tiv thaiv cua sov, siv rau hauv qhov xwm txheej uas xav tau lub zog siab.
2. Qib kev ua tau zoo: Zoo ib yam li cov ntsia hlau hlau ntawm qib 8.8 thiab 12.9, cov ntsia hlau titanium kuj muaj qib zog uas yuav tsum tau xaiv raws li qhov yuav tsum tau tsim.
3. Hom taub hau thiab txoj kev tsav: Hexagonal, hla, lub hnub qub zoo li (Torx), thiab lwm yam. Lub hnub qub zoo li tuaj yeem muab kev sib kis torque zoo dua thiab yuav tsis tshua muaj hniav plam.
Kev Kho Mob Nto
4. Anodizing: Nws tuaj yeem tsim ntau yam xim (xws li kub thiab xiav) thiab txhim kho kev hnav tsis kam thiab kev tiv thaiv corrosion.
Lubrication ntawm zaj duab xis qhuav: txhim kho kev ua haujlwm ntawm cov ntsia hlau thiab tiv thaiv kev tom.
Txheej nickel tsis electrolytic: muab qhov nyuaj siab, hnav-resistant, thiab corrosion-resistant nto
Hauv kev xaus lus, titanium screws yog ib qho khoom siv engineering uas tsim los rau kev ua tau zoo tshaj plaws. Nws daws qhov kev tsis sib haum xeeb tseem ceeb ntawm "lub teeb yuag, lub zog siab, thiab kev tiv thaiv corrosion" uas lwm cov ntaub ntawv tsis tuaj yeem sib npaug. Txawm hais tias kim heev, nws yog qhov kev xaiv tsis tuaj yeem hloov pauv hauv cov teb uas muaj kev thov nruj rau nws cov kev ua tau zoo.
