Lub cev Vapor Deposition ntawm hluav taws xob cua sov Tube Electroplating

2.5.1 Lub cev Vapor Deposition (PVD)

Lub cev vapor deposition yog cov txheej txheem ntawm kev hloov cov khoom plating rau hauv atomic, molecular, lossis ionic vapor tshuaj nyob rau hauv lub tshuab nqus tsev siv ntau yam kev siv lub cev, thiab tom qab ntawd muab tso rau ntawm qhov chaw ntawm lub substrate los tsim cov khoom nyias nyias. HocheH et al. [26] los ntawm lub teb chaws Yelemees npaj CrN thiab TiN zaj duab xis ntawm AZ91 magnesium alloy siv cov txheej txheem PVD, thiab tom qab ntawd tso A1203 zaj duab xis txheej siv cov txheej txheem PVD tom qab plasma anodizing kho. Kev tshawb fawb tau pom tias CrN thiab TiN nyuaj ceramic films tau txhim kho hnav tsis kam vim lawv cov thickness thiab hardness, tab sis lawv cov corrosion kuj tau deteriorated vim muaj cov pores nyob rau hauv cov zaj duab xis txheej. Nyob rau hauv sib piv, corrosion kuj ntawm A1203 zaj duab xis txheej yog ntau dua li ntawm CrN zaj duab xis txheej, thiab hnav kuj zoo dua li feem ntau siv anodic oxidation txheej. AltunH [2'1 ntawm Türkiye tau npaj ntau txheej AIN (AIN ntxiv rau AIN ntxiv rau AIN) thiab AIN ntxiv rau TiN zaj duab xis ntawm AZ91D magnesium alloy los ntawm PVD thev naus laus zis. Cov txiaj ntsig tau pom tias ob qho tib si tuaj yeem txhim kho qhov kev tiv thaiv corrosion ntawm cov hlau, thiab cov qub tau zoo dua.

2.5.2 Chemical Vapor Deposition (CVD)

Tshuaj vapor deposition yog cov txheej txheem ntawm kev qhia cov roj uas muaj ib los yog ob peb lub tebchaw uas ua ib tug nyias zaj duab xis rau hauv cov tshuaj tiv thaiv chamber, tso cai rau nws mus tsim cov nyias nyias zaj duab xis los ntawm cov tshuaj tiv thaiv ntawm lub substrate.

Fracassi et al. tso ib sio 2 zaj duab xis txheej rau ntawm qhov chaw ntawm WE43 magnesium alloy siv plasma enhanced CVD txoj kev. Tom qab kev ntsuam xyuas thiab kev soj ntsuam, cov impedance coefficient ntawm deposited zaj duab xis txheej yog 8000 lub sij hawm siab tshaj ntawm cov ntshiab substrate. Pob zeb diamond zoo li carbon (DLC) zaj duab xis muaj npe nrov rau nws cov hardness siab, tsis tshua muaj kev sib txhuam coefficient thiab zoo heev hnav tsis kam, uas tuaj yeem txhim kho cov khoom siv thiab kev sib txhuam ntawm cov khoom. Yamauchi} 29 et al. tso DLC zaj duab xis rau saum npoo ntawm magnesium alloy substrate siv plasma CVD txoj kev. Tom qab kev sim, nws tau pom tias zaj duab xis zoo txo ​​qhov kev sib txhuam coefficient thiab txhim kho hnav thiab corrosion kuj.

Cov khoom siv tau siv nyob rau hauv vapor deposition teasated txheej, tab sis npaj ua zaj duab xiss muaj siab, thiab ntau yam txheej txheem txheej txheej nrog cov txheej txheem muaj zog. Nws tau siv dav hauv kev lag luam niaj hnub no thiab qhia txog kev loj hlob dav dav.
