Lub unconventional zog ntawm titanium alloys qhia

Yuav ua li cas rau lub siab thaum koj xav txog hlau? Hnyav, xeb, thiab txias? Niaj hnub no cov ntsiab lus, titanium alloys, yuav twv koj qhov kev xav. Nws tuaj yeem nyob hauv dej tau ntau xyoo yam tsis muaj xeb, ua lub teeb zoo li yas tsis tau nyuaj dua li cov hlau, kev cog lus nrog tib neeg cov pob txha, thiab txawm hloov xim zoo li zaj sawv. Cov cuab yeej counterintuitive zais dab tsi scientific secrets? Hnub no, peb yuav nthuav tawm cov lus teb ib los ntawm ib qho.

 

 

 

Rusting yog ib qho tshwm sim rau cov hlau, tab sis titanium alloys yog qhov tshwj xeeb. Submerge titanium alloys hauv dej hiav txwv tau kaum xyoo, thiab lawv tseem ci ntsa iab thiab tshiab. faus hauv av tau ntau xyoo lawm, lawv qhov chaw tseem du thiab tshiab. Txawm tias qhov zoo tshaj plaws, lawv tuaj yeem siv los khaws cov khib nyiab nuclear, xav txog qhov corrosiveness ntawm nuclear pov tseg yog txaus los rhuav tshem stainless hlau.

 

Qhov zais cia nyob hauv cov yeeb yaj kiab oxide pom tsis pom: lub sijhawm titanium alloy los rau hauv kev sib cuag nrog huab cua, ib qho oxide zaj duab xis tsuas yog ob peb nanometers tuab (10,000 npaug ntawm cov plaub hau nyias) tam sim ntawm nws qhov chaw. Cov yeeb yaj kiab no ua haujlwm zoo li "cov cuab yeej tsis muaj zog," tag nrho cais cov titanium los ntawm cov dej sab nraud, cov kua qaub, thiab ntsev. Qhov tseem ceeb tshaj plaws, thaum cov yeeb yaj kiab no tau khawb, titanium tam sim ntawd "sau" oxygen los ntawm huab cua kom rov tsim cov yeeb yaj kiab oxide tshiab ntawm qhov chaw puas tsuaj -tseem ceeb muaj qhov ua tau zoo - hauv "qhov txhab kho" muaj peev xwm.

 

 

 

Nqa ob lub iav thav duab ua los ntawm titanium alloy, thiab koj yuav xav tias, "Puas yog hlau tiag tiag?"- nws qhov ceev tsuas yog 60% ntawm cov hlau (zoo ib yam li txhuas), tab sis nws lub zog yog piv rau hlau. Cov cuab yeej "lub teeb thiab muaj zog" no ua rau titanium alloy nyiam nyob rau hauv aerospace: aircraft fuselages ua los ntawm titanium alloy yuav ua tau 30% sib dua li cov hlau ua; tsheb kauj vab thav duab ua los ntawm titanium alloy yog lub teeb yuag thiab ruaj khov, ua rau kev caij tsheb zoo li "lub teeb yuag".

 

 

Hauv kev phais orthopedic, titanium alloy yog tib yam hlau uas tuaj yeem "loj hlob" rau hauv pob txha. Thaum cov kws kho mob cog cov titanium alloy cov pob qij txha lossis cov hniav cog rau hauv tib neeg lub cev, nws tsis ua rau tsis lees paub zoo li stainless hlau. Hloov chaw, cov pob txha pob txha maj mam npog ntawm qhov chaw ntawm titanium, tsim "osseointegration"-tsuas yog, cov pob txha kho cov titanium raws li nws tus kheej thiab khov kho "npog" nws.

 

 

Cov hlau qub tsuas tuaj yeem hloov xim los ntawm cov xim pleev xim lossis electroplating, tab sis cov titanium alloys tau los nrog ib qho kev ua kom yuam kev tshiab -los ntawm kev siv hluav taws xob (anodizing), lawv tuaj yeem hloov mus ua xim zaj sawv xws li paj yeeb, xiav, ntsuab, thiab ntshav, thiab tsis muaj dyes.

Qhov no yog vim anodizing hloov lub thickness ntawm oxide zaj duab xis ntawm titanium nto. Thaum lub teeb ci rau ntawm cov yeeb yaj kiab ntawm cov thicknesses sib txawv, qhov sib txawv thiab cuam tshuam tshwm sim (zoo ib yam li cov qauv xim ntawm xab npum npuas). Piv txwv li:

1. 10 nanometers tuab oxide zaj duab xis → tshwm golden;

2. 30 nanometers tuab → tshwm xiav;

3. 50 nanometers tuab → zoo li ntshav

Qhov kev muaj peev xwm hloov xim yooj yim los ntawm kev cia siab rau cov tuab tau ua rau titanium alloys nyiam tshiab hauv kev lag luam hniav nyiaj hniav kub -titanium necklaces tuaj yeem hloov xim nyob ntawm lub kaum sab xis, ua rau lawv qhov muag ntau dua - ntes ntau dua pob zeb diamond- caj dab caj dab.

 

 

Feem ntau cov hlau "poob siab" ntawm qhov kub thiab txias: hlau ua nkig ntawm -27℃(shattering zoo li iav nrog ib tug kais), thiab txhuas pib mos ntawm 100℃. Tab sis titanium alloys zoo li "Buddhist practitioners" - lawv nyob twj ywm remarkably pliable.

1. Ntawm qhov kub tsis tshua muaj ze ze rau xoom xoom (-273 degree), nws cov tawv tawv tau nce, ua rau nws tsim nyog siv los ua cov tso tsheb hlau luam rau cov roj ntsha liquefied;

2. Nws tuav nws lub zog txawm tias qhov kub ntawm 600 degree. Lub turbine blades ntawm fighter dav hlau cav cia siab rau titanium alloys tiv taus kub thiab siab.

 

 

Ntau tshaj li kaum xyoo dhau los, titanium alloys yog ib qho zoo sib xws nrog " ntuj- cov nqi siab"- kho kom zoo ib tuj ntawm titanium nqi tib yam li refining peb tons ntawm steel, thiab nws tsuas yog siv tau nyob rau hauv siab - kawg teb xws li foob pob ua ntxaij thiab fighter dav hlau. Tab sis tam sim no, koj tuaj yeem yuav titanium alloy frying lauj kaub thiab thermos flasks rau ob peb puas yuan.

 

 

 

Ntau tus neeg ntseeg tias "titanium muaj lub cim xeeb ua haujlwm," tab sis qhov no yog kev nkag siab yuam kev, ib qho uas tuaj yeem rov qab mus rau nws cov qauv qub tom qab khoov yog "titanium{0}}nickel alloy" (nickel-titanium alloy), thaum ntshiab titanium tsis muaj peev xwm no.

Qee cov tub lag luam ib zaug tau tshaj tawm tias "titanium alloy eyeglass thav duab tuaj yeem rov pib dua," tab sis cov neeg siv pom tias "lawv tsis tuaj yeem khoov rov qab" tom qab sim khoov lawv.

 

Nco ntsoov: Ntshiab titanium lub zog yog "lub teeb, lub zog, thiab corrosion resistance," tab sis "zoo li nco" yog ib tug tshwj xeeb feature ntawm titanium-nickel alloys.

Cov khoom zoo li no tsis zoo ntawm titanium alloys tsis ua txhaum txoj cai ntawm physics, tab sis yog sawv cev rau txoj hauv kev tshiab rau tib neeg los tshawb txog lub ntiaj teb hlau. Los ntawm tus kheej - kho lub peev xwm ntawm oxide zaj duab xis rau xim - hloov txoj hauv kev ntawm lub teeb cuam tshuam, thiab nws qhov ruaj khov nyob rau hauv qhov chaw huab cua, txhua lub cuab yeej qhia peb tias cov hlau tsis yog hais txog "rusting, hnyav, thiab txias."
