Micro-arc Oxidation Kho Tshuab Rau Saum Titanium Cov Khoom Hlau
Lub teeb hlau micro-arc oxidation deg kho tshuab yog hom ncaj qha hauv kev loj hlob ntawm cov yeeb yaj kiab ceramic ntawm cov hlau, uas ua lub luag haujlwm ntawm kev tiv thaiv thiab hnav tsis kam. Lub hauv paus ntsiab lus ntawm cov thev naus laus zis no yog tso Ti, Al, Mg thiab lwm lub teeb hlau thiab lawv cov alloys rau hauv qhov hluav taws xob aqueous electrolyte ua anodes. Siv cov txheej txheem electrochemical, nyob rau hauv kev txiav txim siab ua ke ntawm thermochemistry, plasma chemistry thiab electrochemical cov txheej txheem, los ntawm kev tswj tam sim no ntom ntom thiab lwm cov txheej txheem cov txheej txheem kev ua haujlwm, cov pa hluav taws tawm tau tsim rau saum npoo ntawm cov khoom, thiab lub txim hluav taws kub tshwm sim yog siv los tsim micro-arc oxidation me ntsis rau saum npoo ntawm cov khoom siv los tsim cov ntom ntom oxide ceramic txheej, yog li txhim kho nto zoo ntawm titanium thiab titanium alloys Ib hom kev hloov kho tshuab. Cov tshuab no tau tshaj tawm thiab tau txais daim ntawv tso cai thev naus laus zis technology.
Kev coj tsis kam, kev txhim kho corrosion thiab rwb thaiv kev ua haujlwm ntawm cov nplaim hluav taws xob cov khoom lag luam xws li titanium, txhuas, magnesium, thiab lwm yam kev kho los ntawm micro-arc oxidation txheej txheem tau zoo heev. Tsis tas li ntawd, cov txheej txheem kev kho saum npoo av thev naus laus zis tsis muaj kev cuam tshuam ntawm peb cov pov tseg, tsis muaj kuab paug rau ib puag ncig, kev khiav haujlwm luv, kev lag luam yooj yim, thiab kev txuag hluav taws xob zoo thiab kev lag luam. Txoj kev no tuaj yeem hloov cov txheej txheem kev kho saum npoo av ib puag ncig xws li chromium-nickel electroplating thiab anodic oxidation uas muaj cov pa phem loj.
Lub teeb hlau saum npoo micro-arc oxidation ceramic txheej tsim los ntawm micro-arc oxidation txheej txheem thev naus laus zis yog ua ke nrog cov txheej hauv daim ntawv ntawm metallurgical micro-melting los ua denser tiv thaiv zaj duab xis nyob rau saum npoo ntawm cov khoom lag luam. Qhov micro-melting metallurgical tus qauv tiv thaiv zaj duab xis tiv thaiv zoo heev txhim kho qhov corrosion ntawm lub substrate thiab txhim kho lub hardness thiab hnav tsis kam ntawm cov khoom nto. Tom qab kho micro-arc oxidation, qhov tsim micro-oxidized ceramic txheej tsis yog tsuas yog khov kho ua ke nrog cov txheej hauv cov xim hlau me me, tab sis kuj muaj ntau ntawm cov dig muag qhov micro-sau txheej ntawm saum npoo, thiab cov kev faib tawm yog qhov tsis sib xws, thiab thaj chaw tshwj xeeb ntawm thaj chaw yog loj, uas yog qhov zoo rau txo kev sib txhuam Kev tsim cov roj zaj duab xis txuas ntxiv ntawm cov seem txhim kho lubrication cov khoom ntawm qhov chaw, txo qhov kev sib txhuam coefficient thiab ntev lub neej kev pab. Ntawm qhov tod tes, rau cov khoom uas xav tau tshwj xeeb los tiv thaiv xeb txheej txheem kev kho nyob rau saum npoo, cov txheej txheem no tuaj yeem siv ua kev kho ua ntej. Cov txheej txheem micro-arc oxidation nto yog qhov muaj txiaj ntsig zoo rau cov kev kho tom qab zoo xws li kev sib khi lossis hmoov txau, thiab txhim kho qhov kev sib txuas ntawm lub zog ntawm cov txheej tiv thaiv thiab khov kho, thiaj li txhim kho qhov zoo ntawm kev kho saum npoo.
Hlau nto micro-arc oxidation kho tshuab siv tau dav siv hauv aerospace, aviation, riam phom, tshuab, tsheb, tsheb thauj mus los, petrochemical, textile, luam ntawv, hood, hluav taws xob, kev lag luam teeb, kho mob thiab lwm yam lag luam. Titanium, aluminium, magnesium thiab lawv cov alloys Los tiv thaiv xeb thiab hnav-tiv thaiv nyob rau saum npoo ntawm qhov chaw Cov txheej txheem thev naus laus zis no tau tsim kev lag luam, thiab tuaj yeem tsim khoom tsim thiab ua cov txheej txheem ntau yam duab ntawm titanium, txhuas, magnesium thiab lawv cov khoom siv hlau kom tau raws li high yuav tsum ntawm cov neeg siv rau cov khoom nto.
