Titanium siv cov ntaub ntawv Marine Engineering
Dec 07, 2015

Txawm mob hu ua Acquired marine economy los rau txoj kev tus rog niaj hnub, tus tau tsim hauv marine khoom. Xyaum qhia uas tus siab heev marine khoom, ob leeg deep-sea roj thiab cov nkev ntau lawm khoom, lossis nuclear submarines, submersibles thiab lwm yam khoom siv, yog muab kev koom tes nyob hauv titanium cov khoom, hnav, corrosion ua hauj titanium thiab cov titanium alloy ntawv tau rau cov realization marine khoom efficiency siab, lub neej ntev thiab muaj kev cia siab rau ua qhov tshab.

Thiab lub sij hawm tam sim no rau txoj kev titanium hauv tubrog nkoj yam xws li tshuab. Suav teb yog ib lub teb chaws loj ntawm lub ntiaj teb titanium kev lag luam, yog muaj ib tug titanium tag kuj tshawb fawb thiab kev loj hlob, ntau lawm thiab daim ntawv thov qhov system, muaj peev xwm large-scale ntau lawm thiab ntau daim ntaub ntawv ntawm kev Guard, los kom txoj kev loj hlob ntawm marine yam xws li tshuab titanium, tsis tsuas yog tsim nyog, tiam sis nws kuj tau.

Piv nrog hlau, stainless hlau, tooj, txhuas thiab lwm yam ntaub ntawv, titanium yog lub feature mas feem ntau tsis ceev, lub zog loj, kuj corrosion, tab sis kuj muaj peev xwm ntawm hauj seawater yaig, tsis sib nqus, tsis txias brittleness, permeability siab thiab hais txog, uas yog ib qho yooj yim tsim, casting, vuam, kom nws muaj ntau hom ntau marine engineering.

Titanium hauv dej hiav txwv engineering yuav tso saib yus lub tawm kev mus kom tas cov tiam sis muaj ib co disadvantages, thiab teeb meem nyog muaj chaw. Marine engineering yog ntsib ntau txoj kev sib tw, mas nyob hauv kev tsib:

Ua ntej tshaj, hauv zus ntawm titanium khoom tawg yooj yim.

Vim txoj kev siab melting kis (1668), cov kub ua hauj deformation thiab nqaim kho cua sov kub zoo noj, nws yog yooj yim los ua titanium khoom, tshwj xeeb tshaj yog cov loj loj thiab muaj kev kawm titanium khoom. Nws yuav tsum tsis tas cov loj lub tshuab nqus tsev smelting rauv (arc nqus cua sov, electron nqaj hearth txias cua sov thiab mus nias ntxuav cov khoom (forging tshuab, dov cav, extrusion, etc.). Titanium ntau lawm tsev tshuaj peev yog loj loj, mus txog 30 ~ 40 lab (million) / tuj. Titanium khoom ntau lawm tau txog cov cuab yeej siv tshaj qhov qub specifications cov hlau (1633,-16.00,-0.97%) yog tus loj heev los yog ntau tshaj cov khoom, thiab nws tso zis ntau lawm thiab cov khoom siv no tsuas yog ib qhov dozens, es cov nqi siab ntau lawm.

Ntxiv mus, nyob hauv kev tsim khoom muag.

Titanium dabtsi yog khoov zog thiab muaj ntsis (0.9), siab vuam zog coefficient (saum 0.9), thaum lub elastic modulus, kub conduction coefficient thiab damping coefficient muaj tsawg tsawg xwb. Nyob rau hauv tej lub caij, titanium crevice corrosion, galvanic corrosion, thiab hydrogen embrittlement hu rau teeb meem. Vim lub cev, tshuaj thiab txhua yam cov yam ntxwv ntawm titanium, tus tsim tej cuab yeej titanium yuav tsum xyaum tsim lis dej num tshiab thiab kev specifications (xws li kev nyab xeeb tau, luag corrosion, hluav taws kev tiv thaiv kab mob li cas, yam ntxwv tsab ntawv, daim ntawv weld, etc.). Titanium khoom damping coefficient me me (tsuas yog TiNi zoo nco alloy), yog nyob hauv txoj kev siv cov kev co, tas cov yoov tshaj cum los tiv thaiv kev co. Titanium rau hauv muaj teb xwb ob peb xyoo lawm cov keeb kwm, kev luv dua, yog tsim teeb meem ntau nyob rau explored yuav.

Peb, nyob rau hauv cov khoom raug.

Vim tsis muaj cov uas tsis muaj elastic modulus titanium thiab ua txias thaws, thermal conductivity uas tsis muaj qhov chaw yooj yim puas, khawb to, thiab lwm yam, tag nrho cov coj tej yam teeb meem mus titanium feem ntau heev dua, thaum tshav kub kub kho, machining thiab lwm yam, tshuab mature xav tau qhov kev tshawb kawm lub sij hawm ntev.

Plaub, nyob hauv daim ntawv thov.

Vim lub siab corrosion kuj muaj titanium, titanium khoom rau cov "koj" los semi li khoom, khoom kev mus los yog ntev heev, kom txoj kev ib lossis ob, kev siv lub cim peb cov neeg ua hauj lwm yam xws li tshuab thiab kev nyuaj siab muab daim ntawv thov ib tug ntaus, yuav tsis ua ib tug qhia ntawv thiab tsoom kuaj xyuas tej cuab yeej titanium.

Thib tsib, rau cov khoom siv tswvyim xaiv.

Neeg feem coob yeej tseem nyuaj heev rau los ntawm tus "nqi titanium yog kim heev," tus inertia ntawm kev xav. Nyob rau hauv lub peev xwb peevxwm, nyuab nyuab heev siv tshaj li tus hull hlau kim 5 txog 10 zaug ntawm titanium ntaub hloov hlau los yog tooj manufacturing marine khoom. Kuj hais lus, kev mob lub peev one-time titanium tej cuab yeej no yeej zoo kawg thiab, cov technology hab economic zoo tej cuab yeej titanium mas cia lawv txoj hauj lwm nqi them yuav muaj kev cuam tshuam, uas yog mas cia siab rau cov kev pab mus sij hawm ntev kom muaj kev cuam tshuam. Titanium khoom tsim ntaub ntawv rau hauv lub hiav txwv engineering, pab txheeb xyuas thiab cov qib kev hwm universal ua hauj lwm ntau heev.
