Jan 19, 2018| Q1: PVD yog dab tsi?
A1: PVD yog lub npe ntawm Lub Cev Lub Cev Tsis Taus (Physical Vapor Deposition). Nws yog hais txog ib hom yeeb yaj kiab zaj duab xis coj mus siv tshuab uas siv lub cev los ua cov ntaub ntawv tso nyiaj ntawm cov khoom ua haujlwm hauv lub tshuab nqus tsev.
Q2: PVD txheej dab tsi? Lub PVD txheej tshuab yog dab tsi?
A2: Muaj 3 hom PVD (Physical Vapor Deposition) tshuab: Lub tshuab nqus tsev evaporation, lub tshuab nqus plua plav thiab txheej xiam plating. Tus txheeb ze mus rau peb hom PVD kev siv tshuab, sib nug cov nqus plua tshauv khoom yog lub tshuab nqus tsev evaporation tshuab, nqus pluttering txheej tshuab thiab nqus tsev ion plating tshuab . Nyob rau hauv kaum xyoo tsis ntev los no, tshuab nqus tsev ion plating yog tshuab ceev tshaj plaws ntawm kev siv tshuab, nws tau ua ib qho kev kho siab tshaj plaws ntawm cov kev kho cov kab mob niaj hnub no. Dab tsi peb feem ntau hais tias PVD txheej yog hais txog lub tshuab nqus tsev ion plating, thiab feem ntau hu ua PVD txheej tshuab yog lub tshuab nqus tsev ion plating.
Q3: Lub hauv paus ntsiab lus ntawm PVD txheej txheem yog dab tsi?
A3: Cov txheej txheem ntawm ion plating (PVD txheej txheem) yog siv cov cuab yeej tawm hauv kev siv hluav taws xob tsawg hauv siab thiab siab tam sim no, siv cov paug tawm mus ua lub hom phom sij thiab ua rau ionize cov ntaub ntawv evaporated hauv lub tshuab nqus tsev, thiab tom qab ua cov ntaub ntawv evaporated lossis nws cov khoom tso nyiaj rau ntawm lub chaw ua haujlwm hauv kev ua haujlwm ntawm cov hluav taws xob.
Q4: Qhov zoo ntawm PVD txheej txheem uas muab piv nrog tshuaj tshuaj lom (tshuaj plating) yog dab tsi?
A4: Qhov zoo sib xws ntawm cov tshuaj PVD txheej txheem thiab cov tshuaj tsoos tshuaj yog cov uas yog ob hom ntawm kev kho mob, uas txhais tau hais tias txoj ntsiab cai ntawm ob txoj kev yog tag nrho ua rau cov khoom siv rau ntawm lwm cov khoom. Qhov txawv ntawm ob txoj kev yog: PVD coating zaj duab xis tau zoo dua adhesion, dua hardness, zoo coj los tiv thaiv thiab corrosion ua hauj, raws li kev ruaj ntseg zoo dua; PVD txheej muaj ntau hom kab nrib pleev xim ntau yam xim zoo nkauj; thiab cov PVD txheej tsis tau qhia cov khoom tsis zoo lossis cov khoom tsis huv.
Q5: Tau PVD coating hloov tshuaj lom neeg plating?
A5: Ntawm theem no, PVD txheej tsis tuaj yeem hloov tshuaj lom neeg. Dhau li ntawm, PVD txheej yuav tuaj yeem ncaj qha rau ntawm cov hlau tsis huv, tab sis rau lwm cov ntaub ntawv (xws li zinc alloy, tooj liab, hlau, thiab lwm yam), chemical plating ntawm Cr (chromium) yuav tsum tau ua ntej PVD txheej . PVD txheej yog siv hauv qee yam khoom kho khoom siv siab, rau cov kho vajtse pheej yig dua, cov tshuaj lom neeg yog hom kev xaiv.
Q6: Tus cwj pwm ntawm PVD txheej dab tsi yog dab tsi?
A6: Cov yeeb yaj duab coated los ntawm PVD txheej tshuab muaj qhov zoo ntawm kev sib zog, kev coj zoo (tsis tshua muaj coefficient ntawm kev sib txhuam), zoo corrosion kuj thiab tshuaj stability, lub neej ntev kev ua haujlwm, thiab lwm yam. tsos kho kom zoo nkauj ntawm workpiece.
Q7: Dab tsi substrate tau PVD coated rau?
A7: PVD zaj duab xis tau plated ncaj qha rau cov hlau tsis muaj steel thiab cemented carbide, rau zinc alloy, tooj liab, hlau thiab lwm yam kev tuag-castings, tshuaj plating ntawm Cr (chromium) yuav tsum tau ua ntej PVD txheej
Q8: Yam dab tsi ntawm hom yeeb yaj kiab tuaj yeem plated tau los ntawm PVD txheej txheem tshuab?
A8: PVD txheej txheem tshuab yog ib thaj chaw zoo rau txoj kev kho mob uas ua tau tiav ntawm micron qib txheej tsis muaj kev ua qias tuaj. Nws tuaj yeem tso ntau yam duab hlau (aluminium, titanium, zirconium, chromium, etc.), nitride films (TiN, ZrN, CrN, TiAlN), carbide film (TiC, TiCN) thiab oxide zaj duab xis xws li TiO.
Q9: Lub thickness ntawm PVD txheej yog dab tsi?
A9: Lub thickness ntawm PVD txheej xim yog nyob rau ntawm qhov kev txiav txim ntawm microns, feem ntau 0.1 μm mus rau 5 μm. Lub thickness ntawm tus hniav txheej hniav feem ntau yog 0.1 μm rau 1 μm, uas yuav xyuas kom muaj ntau yam ntawm lub cev thiab tshuaj ntawm cov hluav taws xob tsis cuam tshuam tus thawj loj ntawm cov workpiece, nyias zaj duab xis kuj tseem muaj qhov tib qhov loj ntawm lub workpiece, dhau li ntawd, qhov kev ua ntxiv tsis yog xav tau tom qab plating.
Q10: Cov xim txheej twg ntawm PVD txheej yog plated?
A10: Tam sim no, cov xim muaj xim nyob rau hauv zaj duab xis xws li tsaus kub daj, lub teeb daj kub, xim av, tooj liab, grey, dub, gray dub, muaj tsos zoo thiab zoo li ntawd. Los ntawm kev tswj cov ciaj ciam tsis zoo hauv txheej txheej, peb tuaj yeem tswj cov xim ntawm PVD coatings. Tom qab txheej txheem, cov xim xim yuav ntsuas tau los ntawm qhov ntsuas twj paj nruas kom paub cov xim thiab txiav txim siab seb cov xim xim li cas los tau.
