Yuav Titanium Rauj Rotion
Nyob rau hauv tib neeg cov khoom siv ib txwm muaj, "muaj yuav luag ib daim ntawv qhia txog cov hlau thiab kev sib cav sib ceg Hlau "{{. titanium rauj, raws li tus neeg sawv cev raug ntawm titanium alloy hauv kev siv corrosies, nws yog dab tsi yog nws corrosion tsis kam? Puas yog nws xeb zoo li cov hlau zoo nkauj? Cov lus teb rau lo lus nug no nyob rau hauv kev sib sib zog sib xyaw ntawm titanium cov qauv atomic, cov ntaub ntawv sib txawv thiab cov ntaub ntawv kawm txuj ci {}}
Titanium's "Ntuj Txhaj Tshuaj": atomic qauv txiav txim los tiv thaiv cov noob corrosion
Cov ntsiab lus ntawm cov hlau xeb yog entrochemical corrosion-profection micro corriguration yog 3D²4s², thiab nws yooj yim heev rau poob cov hluav taws xob hauv ib puag ncig ntawm kev ruaj khov ions, tab sis tus txheej txheem no tsis cuam tshuam hlau sib cais, tab sis es tsis txhob ua yeeb yaj kiab oxide oxygen .
Cov yeeb yaj kiab titanium oxide (ti₂) muaj qhov sib txawv ntawm kev siv pa taws, thiab cov duab tuab sildle {1 tsis yog-corrosive nyob rau hauv chav tsev kub, tso lub hauv paus rau nws cov anti-xeb ua haujlwm .
Tus "phab ntsa hlau" ntawm cov zaj duab xis passive: tshuaj lom neeg ruaj khov tsim cov thaiv kev tiv thaiv corrosion
Cov yeeb yaj kiab titanium oxide (ti₂) yog cov khoom siv hluav taws xob ntau {}} nws cov qauv siv lead ua yog rutile yog rutile yog rutile yog rutile yog rutile yog rutile yog rutile yog rutile yog rutile yog rutile yog rutile yog rutile yog rutile yog rutile yog rutile yog rutile yog rutile yog rutile yog rutile yog rutile yog rutile yog rutile yog rutile yog rutile yog rutile yog rutile yog rutile yog rute thiab muaj cov yam ntxwv hauv qab no:
Nthuav thiab tsis-ntxeem tau: tio₂ zaj duab xis txheej muaj cov nplej zoo thiab muaj peev xwm kaw tau zoo dua 0.1%
Siab Adhesion: Lub Film Txheej yog chiv ua ke rau Titanium substrate, thiab lub zog ua kom muaj zog tshaj li ntawm cov tev ntawm cov tev ntawm zaj duab xis txheej;
Acid thiab alkali tsis kam: ti₂ tseem ruaj khov nyob rau hauv lub ntsej muag ntawm {}}} Txawm nyob rau hauv cov hlau muaj zog heev, ntau dua li cov hlau thiab txhuas.
Qhov hluav taws xob ruaj khov no tso cai rau cov kaus mom ntev hauv cov khoom lag luam uas tsis ua haujlwm zoo li cov khoom lag luam hauv hiav txwv xws li cov ntaub ntawv qub xws li Stainless Hlau {}}
Anti-pitting thiab compevice corrosion: tawg qhov "tuag taus" ntawm ib puag ncig tob
Hauv kev sib sib zog nqus hiav txwv kev tshawb nrhiav, chloride ions (cl l) Chloride ions:
Pitting kuj: lub titanium oxide zaj duab xis yuav raug puas tsuaj rau chloride {
Crevice corrosion: nyob rau hauv cov xov kev sib txuas, zam kev sib txawv ntawm cov kab mob ntawm titanium tuaj yeem tsim kev pheej hmoo ntawm cov kev pheej hmoo ntawm kev pheej hmoo ntawm kev pheej hmoo ntawm kev pheej hmoo ntawm cov kev pheej hmoo ntawm kev pheej hmoo ntawm kev pheej hmoo ntawm cov kev pheej hmoo ntawm cov kab mob corrosion, tsis txhob ua yeeb yaj kiab ua yeeb yam rau hauv thiab sab nraud ntawm kev pheej hmoo ntawm cov kev pheej hmoo ntawm cov kab mob sib txawv
Qhov no "insensitive" tus yam ntxwv rau chloride ions ua titoride rauj cov khoom zoo tshaj plaws rau cov khoom sib sib zog nqus rau cov khoom sib sib zog nqus cov khoom noj {1}
"Bistility" ntawm cov khoom kub qis thiab kub: ib qho "txhua-round player" uas yoog raws ib puag ncig heev
Cov hlau corrosion feem ntau nce nrog kev nce qib, tab sis cov zaj duab xis passive zaj duab xis ntawm titanium tuaj yeem ruaj khov nyob rau ntawm qhov kub:
Ib puag ncig kub tsawg: ntawm cov kua nitrogen kub ntawm {}}}} Cov duab kos duab, uas yog tsim nyog rau cov dej kub tsawg li cov dej num hauv tsev loj lossis chaw muaj dej num hauv tsev loj.
Kev kub siab ib puag ncig: nyob rau hauv siab dej hiav txwv saum dej ua rau {{1} {1} {1} {1} {{}}
Qhov no "tsis nkig ntawm tsawg kub thiab tsis mos nyob rau ntawm lub rauj rauj kom ua haujlwm nyob rau hauv cov dej khov rau hydrothermal rau hydrothermal vents .
Los ntawm lub ntuj los tiv thaiv corrosion ntawm cov qauv atomic rau cov tshuaj ruaj khov ntawm cov zaj duab xis passivation; Los ntawm kev tiv thaiv kab mob ions rau lub bistabation ntawm huab cua ntawm cov lus dab neeg ntawm lub teb chaws ntawm lub teb chaws ntawm lub teb chaws ntawm lub teb chaws ntawm lub teb chaws kev ua tus nqi ntawm titanium alloys yog maj zuj zus, thiab nws daim ntawv thov txo qis, thiab nws daim ntawv thov tau nthuav mus rau tom peg xeem no {}}}}
