Yuav ua li cas hlau 3d luam ntawv txhim kho kho corrosion tsis kam thiab oxidation tsis kam ntawm cov khoom siv zog?

Cov teeb meem nrog corrosion thiab oxidation uas cov khoom siv zog muaj los daws
Teeb meem nrog corrosion
Muaj feem ntau ntau cov tshuaj corrosive hauv cov chaw uas cov khoom siv hluav taws xob ua haujlwm. Drilling kua siv hauv kev rho tawm muaj ntau ntsev, acid, thiab cov kab mob me me, uas tuaj yeem ua rau muaj cov khoom siv drilling drilling. Thaum lub sij hawm ntau lawm tshuaj zog, txawv acid, alkali, ntsev, thiab cov kuab tshuaj organic tuaj yeem hnov ​​mob nrog cov hlau ntawm cov cuab yeej. Qhov no tuaj yeem ua cov phab ntsa ntawm cov khoom siv thinner, tsis muaj zog, thiab txawm tias ua rau xau. Piv txwv li, kev sib pauv cua sov hauv kev ua kom sov yog nthuav tawm cov kab sib txuas uas zoo li cov sulfides thiab chlorides rau lub sijhawm ntev. Qhov no tuaj yeem yooj yim ua rau pitting corrosion, crevice corrosion, thiab lwm yam teeb meem uas ua rau nws nyuaj txav thiab ua kom luv lub neej ntawm cov cuab yeej.
Teeb meem nrog oxidation
Ib qho ntawm feem ntau ua haujlwm ib puag ncig rau cov khoom siv hluav taws xob yog qhov kub. Piv txwv li, boilers nyob rau hauv thermal nroj tsuag thiab combusation chambers nyob rau hauv cov roj Turbines. Thaum cov hlau yog nyob rau hauv cov chaw kub no, lawv tau hnov ​​cov oxygen los tsim cov roj oxide. Raws li Oxide txheej tau tuab dua, cov khoom siv cov neeg kho tshuab zoo yuav maj mam mus zuj zus. Piv txwv li, nws yuav dhau los ua neeg tsis muaj zog, tsis muaj zog, thiab muaj feem cuam tshuam thiab swb. Piv txwv li, thaum lub turbine tawg ntawm cov pa roj ua haujlwm hauv cov roj kub kub, oxide teev yuav ua rau saum npoo. Thaum cov nplai peel tawm, lawv yuav ua kom hnav kom ceev thiab corrosion ntawm cov hniav, uas yuav txo qis lub cav kev ua tau zoo thiab ntseeg tau.
Cov ntsiab cai thiab kev ua rau cov hlau 3D luam tawm ntau tiv taus corrosion
Txhim kho cov muaj pes tsawg leeg thiab microstructure ntawm cov khoom
Hlau 3D luam tawm tuaj yeem tswj hwm cov pleev thiab microstructure ntawm cov ntaub ntawv siv khoom thiab ib puag ncig uas nws yuav raug siv. Ntxiv cov ntsiab lus xws li chromium, npib tsib xee, thiab molybdenum cov ntaub ntawv tuaj yeem ua rau lawv tsis tshua muaj xeb. Piv txwv li, ntxiv chromium rau stainless hlau yuav tsim kev tiv thaiv tuab txheej ntawm chromium oxide ntawm cov hlau nto. Qhov no yuav ua kom cov tshuaj corrosive los ntawm kev tuaj mus rau hauv kov nrog hlau substrate, uas yuav ua rau cov hlau tsis muaj zog tiv thaiv corrosion. Cov cuab yeej siv hluav taws xob hlau 3D tuaj yeem cuam tshuam tawm cov txheej txheem Alloy, uas daws cov teeb meem ntawm kev sib cais uas tuaj yeem tshwm sim hauv cov txheej txheem kev ua yeeb yam thiab cov txheej txheem forging. Qhov no ua rau cov ntaub ntawv 'corrosion tiv taus ntau dua.
Tswj cov ntawv luam tawm zoo li laser fais fab, txheej ceev, txheej thickness, thiab li tseem tuaj yeem hloov cov ntaub ntawv microstructure hauv cov khoom siv hlau 3D. Piv txwv li, cov qauv txiv me me tuaj yeem ua tau los ntawm kev nplua- tuning cov chaw luam ntawv. Qhov no tuaj yeem ua rau cov khoom ntxiv tiv taus corrosion vim tias cov ciaj ciam nplej yog qhov uas corrosion yog tshwm sim. Cov hmoov nplej zoo qhia ntau cov ciaj ciam thiab ntev dua, cov kab uas muaj ntev dua, uas qeeb qeeb ntawm txoj hlab corrosion.
Ua cov qauv uas tsis muaj xeb
Nws yog ib qho nyuaj rau cov txheej txheem kev lag luam ib txwm ua rau cov ntu nrog kev tawm tsam teeb meem, tab sis cov tshuab corrosion, tab sis cov tshuab corrosion), tab sis cov tshuab corrosion tau sai sai ua cov qauv zoo sai sai. Piv txwv li, micro- nano cov qauv yuav siv tau los ua kom anti- corrosion txheej ntawm cov khoom. Cov txheej txheej no tuaj yeem ua rau nws nyuaj rau cov tshuaj corrosive los mus kov cov hlau, uas ua rau lawv muaj txiaj ntsig zoo hauv kev tiv thaiv corrosion. Koj tseem tuaj yeem ua qhov chaw nrog sab hauv uas tuaj yeem khaws cia los ntawm kev xeb los ntawm kev tso cov tshuaj cawm lossis txias txias rau hauv cov channel. Piv txwv li, cov tshuab luam ntawv hlau yog siv los ua cov pob qij txha nrog ov {9} Corrosion raws cov roj pipelines. Cov channel no tuaj yeem ua ntu zus nrog anti - corrosion tebchaw kom cov pob qij txha los ntawm xeb.
Cov ntsiab cai thiab txoj kev siv cov hlau 3D luam ntawv los ua rau antioxidant ua haujlwm zoo dua
Tsim cov alloys uas yog ob qho tib si muaj zog thiab antioxidant
Hlau 3D Printing Ua Kom Nws Muaj Peev Xwm Ua Kom Siab Tshiab-} performanceults alloys uas tsis xeb. Cov kws tshawb nrhiav tuaj yeem ua thiab txhim kho cov ntaub ntawv alloy nrog qee cov qauv thiab cov qauv sib xyaw raws li lawv ua haujlwm raws li antioxidants. Nickel {{4 4}}} Raws siab high- kub alloys, piv txwv li tiv thaiv oxidation. Kev siv tshuab hlau 3DD koj tswj hwm tus nqi thiab kev kawm ntawm cov sib txawv hauv cov alloy heev, uas ua rau nws tiv taus oxidation. Koj kuj tuaj yeem ntxiv lub ntiaj teb tsis tshua muaj ntau rau cov alloy. Cov no tuaj yeem ua cov nplej kom me dua, ntxuav cov qoob loo nplej, thiab ua kom muaj zog ntawm cov cua sov thiab tsis tshua muaj oxidize.
Ua ib qho gradient anti -} oxidation txheej
Gradient coating yog ib hom txheej uas muaj ob qho kev sib xyaw thiab cov qauv gradient clientural. Qhov no ua rau nws muaj peev xwm zoo dua los daws qhov hloov pauv hauv qhov kub thiab qhov ntsuas oxidation. Kev siv tshuab ua hlau 3D ua rau gradient anti {}}} oxidation txheej nrog cov raug. Piv txwv li, thaum kev txhim kho gradient anti - Cov txheej txheej av, thaum cov txheej sab nraud ua tau txoj haujlwm sab nraud ua kev tiv thaiv oxidation. Cov txheej txheej tus qauv thiab muaj pes tsawg leeg hloov maj mam li kub thiab txias kom tiv thaiv nplooj los ntawm oxidation ntawm ntau qhov kub. Qhov no ua rau cov nplooj ntev ntev thiab ua haujlwm zoo dua li antioxidant.
