Cov hau kev kom tsis txhob muaj hydrogen embrittlement thiab nto txwv ntawm titanium rods

Nyob rau hauv lub tsev rau khoom, kab ntawm titanium tuav tau mottled xeb ntawm qhov chaw vim yog tsis muaj zog cia. Tom qab sim, nws tau pom tias hydrogen embrittlement tau tshwm sim sab hauv. Tsis tsuas yog lawv puas tau ncaj qha scrap thiab ua rau kev poob nyiaj loj, tab sis lawv kuj tuaj yeem ncua kev xa khoom tom ntej xaj. Rau cov tuam txhab xws li aerospace thiab cov cuab yeej siv kho mob uas cia siab rau titanium ceg, hydrogen embrittlement thiab cov paug ntawm "dai ntawm lawv lub taub hau. Kab lus no yuav tob tob rau cov ntsiab lus mob ntawm titanium bar cov kev daws teeb meem thiab kev tiv thaiv kev tiv thaiv zoo thiab siv tau cov nqi raw thiab cov nqi hauv qab.

Muaj peev xwm muaj peev xwm thiab ua rau titanium bar cov khoom lag luam

Hauv kev tswj hwm ntawm titanium bar cov khoom ua, cov tuam txhab feem ntau tau ntsib ob qho teeb meem loj: hydrogen clittlement thiab nto paug. Hydrogen embrittlement ua rau cov qauv sab hauv ntawm titittures, thiab kev sib tsoo tam sim ntawd tau tshwm sim thaum ua tiav lossis siv, cuam tshuam rau cov khoom muaj kev nyab xeeb; Cov kev sib kis tau manifests nws tus kheej hauv oxidation, roj stuces cov nplaum thiab lwm yam teeb meem, tab sis kuj yuav cuam tshuam lawv cov tshuaj thiab kev ua yog. Thaum cov teeb meem no tshwm sim, tus nqi ntau lawm yuav nce ntawm tsawg kawg, thiab tag nrho cov batch ntawm raw khoom yuav tau scrapped ntawm qhov phem tshaj, cuam tshuam rau cov phiaj xwm ntau lawm.

Lub hydrogen embrittlement teeb meem feem ntau yog los ntawm kev sib cuag ntawm titanium pas nrig nrog hydrogen-muaj xov xwm thaum cia. Hydrogen atoms nkag mus rau hauv titanium lattice, aggregate los ua cov moleculate molecules, thiab tsim sab hauv kev ntxhov siab kom ua rau tawg. Cov kev paug tau feem ntau tshwm sim los ntawm kev cia siab ntawm huab cua ib puag ncig, tiv thaiv corrosive gases nyob rau hauv huab cua, tiv tauj nrog lwm cov hlau lossis tshuaj lom neeg, thiab tsis tsim nyog thaum lub sijhawm thauj mus los. Tsis tas li ntawd, cov tsis muaj cov khoom lag luam tawm tswv yim thiab kev saib xyuas tsis tu ncua thiab kev saib xyuas titanium kuj tseem yog vim li cas tseem ceeb rau lub sijhawm ntev ntawm qhov teeb meem.

Kev tswj hwm kev tswj hwm kev paub rau cov khoom lag luam titanium rod

Txhawm rau kom tsis txhob muaj hydrogen embrittlement thiab nto txwv ntawm titanium rods, nws yog qhov tsim nyog los pib ntawm ib puag ncig tswj, kev cia siab, kev tswj hwm txhua hnub thiab lwm yam. Nyob rau hauv cov nqe lus ntawm cia ib puag ncig, khaws cov khoom ntim kom qhuav thiab siv tau nruj me ntsis kom tsis txhob muaj cov av noo nyob ntawm qhov chaw kom nrawm dua ntawm cov pas dej xidation; Siv kev tiv thaiv nitrogen tiv thaiv kom cais tawm cov huab cua thiab tiv thaiv hydrogen atoms thiab corrosive gases los ntawm kev hu rau Titanium pas dej.

Nyob rau hauv cov nqe lus ntawm cov txheej txheem cia, cov nplais titanium yuav tsum tau cais kom tsis txhob muaj kev sib cuag ncaj qha nrog hlau thiab tooj liab los tiv thaiv cov pob zeb loj. Tshwj xeeb yas lossis ntoo pallets thiab nkhaus yuav tsum tau siv los txo kev sib txhuam thiab khawb; Cov saum npoo ntawm titanium tuav yuav tsum muaj kev tiv thaiv, xws li thov anti-xeb roj thiab npog nrog cov yeeb yaj kiab noo noo. Hauv kev tswj hwm txhua hnub, ib qho kev tshuaj xyuas kev kuaj xyuas ib txwm yuav tsum tau tsim los tshawb xyuas cov xeev saum npoo thiab chaw cia khoom ntawm titanium tuav; Qauv kho cov haujlwm thiab siv cov tawv mos lwj kom tsis txhob sib tsoo thiab khawb; Khaws cov ntaub ntawv zoo hauv thiab tawm ntawm cov chaw rau khoom, ua raws "thawj zaug" thawj lub hauv paus ntsiab lus, thiab txo cov voj voog cia ntawm titanium tuav.

Tus nqi tiv thaiv deb ntawm cov khoom lag luam scientific

Kev siv cov scientific titanium bar Cov tswv yim tswj hwm nqa cov txiaj ntsig dhau ntawm kev txo cov khoom muaj sia. Los ntawm cov kev pom muaj nqi, ua kom muaj cov teeb meem tsis huv thiab txo cov nqi rov ua haujlwm thiab txo cov nqi ntawm cov khoom muaj teeb meem zoo; Los ntawm kev pom ntau lawm, qhov zoo tshaj plaws ruaj ntseg ntawm titanium tuav yog lav, thiab ua tiav kev ua tau zoo thiab cov khoom tawm tau zoo dua; Los ntawm lub sij hawm kev loj hlob mus ntev, ib qho kev ua lag luam ua tiav yuav pab cov tuam txhab sib tw, txhim kho cov lag luam hom kev sib tw, txhim kho cov lag luam hom kev sib tw uas txhim khu kev qha.

Phased siv cov kauj ruam

(1) Qhov xwm txheej tam sim no: Ua kev soj ntsuam cov khoom lag luam titanium uas twb muaj lawm, thiab cov txheej txheem kev tswj hwm, thiab sau cov ntsiab lus uas twb muaj lawm thiab tsis muaj kev sib kis.

(2) Kev hloov ib puag ncig: Raws li cov khoom siv titanium thiab cov av noo, thiab ntxuav cov khoom uas tuaj yeem ua rau paug rau hauv lub tsev rau khoom.

Kev tsim kho kom zoo: yuav cov cuab yeej tshwj xeeb cia, rov kho dua thiab khaws cov lus nug titanium tuav, thiab ua tiav kev tiv thaiv sab nrauv.

(3) Kev Tsim Kho Cov: Tsim cov titanium bar cov peev txheej tswj cov kev ntsuas, hauv thiab tawm ntawm cov txheej txheem cia, tuav cov qauv thiab lwm yam kev xav tau.

(4) Kev Cob Qhia Cov Neeg Ua Haujlwm: Cov thawj tswj hwm khoom lag luam thiab cov neeg ua haujlwm tuav cov neeg ua haujlwm kom ntseeg tau tias lawv tus tswv qhov raug bar cia thiab kev tswj hwm.

(5) Kev Ntsuam Xyuas Nruam: Tsim cov lus nug kev tswj hwm kev ntsuas cov tshuab, tsis tu ncua tshuaj xyuas cov ntaub ntawv hauv cov lus pov thawj raws li cov xwm txheej tiag tiag.

Txhua yam ntawm titanium bar cov khoom lag luam muaj feem xyuam nrog tus nqi thiab kev ua tau zoo ntawm kev lag luam. Tsis txhob cia hydrogen embrittlement thiab kev tsis huv cov txiaj ntsig thiab lub koob npe nrov. Siv sijhawm tam sim no, saib cov phiaj xwm tswj kev tshawb fawb los hloov kho cov lus nug ua haujlwm, thiab tsim cov khoom siv raw zoo defense Defense kab rau ntau lawm!

Qhov saum toj no piav qhia cov ntsiab lus tseem ceeb ntawm titanium bar cov khoom lag luam kev tswj hwm los ntawm ntau qhov ntev. Yog tias koj xav tias qee ntu xav tau kev xav tau ntxiv lossis cov ntaub ntawv, lossis kev tsom xam cov ntsiab lus xav tau hloov kho, thov xav qhia rau peb paub.
