Txheej txheej
Tam sim no, cov txheej txheem dav dav siv dav dav yog cov tshuaj vapor deposition (CVD) thiab lub cev vapor deposition (PVD), nrog rau qee cov txheej txheem txheej txheem tshiab xws li ntshav plasma chemical vapor deposition (PCVD) thiab ion beam assisted deposition (IBAD).
(1)CVD (cov tshuaj vapor deposition)
UHu nkauj lub vapour, hydrogen thiab lwm yam chemical Cheebtsam ntawm hlau halides, decomposition, thermo-combination thiab lwm yam gas-solid tshua ntawm kub kub (950 ~ 1050 ℃) los tsim ib tug khoom deposition txheej rau ntawm qhov chaw.hniavsubstrate. CVD txheej txheej txheem muaj qhov kub thiab txias, txhim khu kev qha kev sib txuas, tab sis tuaj yeem ua rau muaj teeb meem xws li kev ntxhov siab tensile seem.
(2)PVD (lub cev vapor deposition)
Nyob rau hauv lub tshuab nqus tsev, tsis tshua muaj voltage, siab tam sim no arc tawm tshuab yog siv los evaporate lub hom phiaj cov ntaub ntawv thiab ionise nws nrog cov roj, uas yog tso rau ntawm lubhniavsubstrate siv cov nyhuv accelerating ntawm hluav taws xob teb. PVD txheej muaj qhov kub thiab txias (300 ~ 500 ° C), uas yuav tsis ua puas lub hardness thiab qhov tseeb ntawm qhovhniavsubstrate, thiab txheej txheej muaj qib siab ntawm purity thiab densification, thiab ruaj khov rau cov substrate.
(3)PCVD (Plasma Chemical Vapor Deposition)
Siv plasma los txhawb cov tshuaj tiv thaiv thiab txo cov txheej txheem kub kom qis dua 600 ° C. Nws yog qhov tsim nyog rau lub sijhawm uas qhov kev sib hloov lossis kev sib pauv tsis yooj yim tshwm sim ntawm cov cemented carbide substrate thiab cov khoom txheej.
(4)IBAD (Ion Beam Assisted Deposition Technology)
Thaum tso cov txheej txheem nyob rau hauv lub caij txias, foob pob hluav taws tsis tu ncua nrog cov ion beam ntawm qee lub zog los txhim kho lub zog sib txuas ntawm cov txheej thiab cov substrate.
Qhov zoo ntawm coatedhniavs
lTxhim kho hnav tsis kam: Cov khoom siv txheej muaj siab hardness thiab hnav tsis kam, txuas ntxivhniavlub neej.
lTxhim kho oxidation tsis kam: Tnws txheej ua raws li tshuaj lom neeg thiab thermal barrier, txo diffusion thiab tshuaj tiv thaiv ntawm covhniavthiab lub workpiece.
lTxo kev sib txhuam: Coatings muaj cov coefficient tsawg ntawm kev sib txhuam, txhim kho cov txheej txheem txiav thiab machining zoo.
lUa kom cov hlau qaug zog ua haujlwm: Coated cov ntaub ntawv zoo tiv taus qaug zog tawg txuas ntxiv.
lUa kom thermal shock tsis kam: Tnws txheej cov khoom muaj thermal stability zoo thiab yoog mus rau qhov kub thiab txias ib puag ncig.
lTiv thaiv corrosion: Corrosion tuaj yeem yog ib qho teeb meem loj, tshwj xeeb tshaj yog rau cov hniav hlau, thiab cov txheej txheem zoo, tsim tau zoo tuaj yeem txo cov kev tu ncua thiab kev pheej hmoo ntawm corrosion.
Extend khoom lub neej: BLade coatings tuaj yeem txhim kho durability, kev puas tsuaj tsis kam thiab tag nrho cov hniav ua haujlwm, thiab cov hniav txheej txheej zoo tuaj yeem pab ntev lub neej ntawm kev lag luam txiav.hniavs, uas yog ib qho tseem ceeb rau txo downtime thiab txhim kho efficiency.
Koj yuav tsum xav txog cov hauv qab no ua ntej xaiv cov hniav txheej
(1)Khoom siv
Ua ntej, nws yog ib qho tseem ceeb los txheeb xyuas qhov twg cov khoom yuav raug siv, xws li kev ua zaub mov, tsheb, aerospace, khoom siv kho mob, thiab lwm yam. Qhov no yuav muaj kev cuam tshuam ncaj qha rau kev xaiv txheej, thiab yog tias koj ua haujlwm hauv kev lag luam ua zaub mov. koj yuav tsum tau xyuas kom meej tias koj cov hniav txheej yog FDA raws thiab tsis muaj tshuaj lom. TiCN thiab Teflon yog cov txheej txheej zoo heev uas tsis muaj tshuaj lom thiab FDA ua raws lossis pom zoo, uas tso cai rau koj siv lawv hauv kev ua zaub mov yam tsis muaj kev pheej hmoo kis kab mob ntawm koj cov khoom nrog cov tshuaj phem lossis cov khoom siv. Yog tias koj qhov kev lag luam xav tau cov hniav hloov tau, DLC txheej thiab tawv chrome yog qhov kev xaiv zoo heev.
(2)Xyuas kom cov hniav zoo
Ntxiv nrog rau kev saib xyuas zoo los ntawm cov chaw tsim khoom, koj yuav tsum xyuas kom meej tias koj cov riam yog qhov zoo ua ntej siv cov txheej txheem. Txawm tias muaj cov txheej txheem zoo, cov hniav tsis zoo yuav tsis kav ntev heev, thiab qhov no tuaj yeem cuam tshuam cov txiaj ntsig ntawm txheej. Yog tias koj xav ua kom zoo tshaj plaws ntawm cov hniav txheej, koj yuav tsum tau ua kom paub tseeb tias koj pib nrog cov khoom lag luam zoo..
(3)Cov kev xav tau ntawm kev ua haujlwm
Cov no muaj xws li hardness, abrasion kuj, corrosion kuj, kub tsis kam, adhesion kuj, thiab lwm yam.
(4)Kev txiav txim siab nqi
Tus nqi ntawm cov khoom siv txheej thiab txheej txheej kuj tseem ceeb rau kev txiav txim siab thaum xaiv.
