Raws li kev tsim khoom niaj hnub tseem xav tau kev ua haujlwm siab dua los ntawm cov khoom siv, tshwj xeeb tshaj yog cov kev ua haujlwm nyob rau hauv huab cua xws li kub kub, siab siab, thiab kev sib txhuam muaj zog, txheej tshuab tau dhau los ua qhov tseem ceeb. Daim ntawv thov ntawm cov coatings nyuaj plays lub luag haujlwm tseem ceeb hauv kev txhim kho cov cuab yeej siv tau ntev, kev ua haujlwm precision, thiab tag nrho cov khoom ua tau zoo. PVD (Physical Vapor Deposition) thev naus laus zis thev naus laus zis yog qhov ua ntej ntawm kev tsim kho tshiab hauv daim teb no, tsav kev nce qib hauv txheej txheej txheej txheem.
No.1 Cov txheej txheem PVD yog dab tsi?
Cov txheej txheem PVD suav nrog kev siv lub cev los hloov cov ntaub ntawv txheej los ntawm cov khoom siv los yog kua hauv lub xeev gaseous, tom qab ntawd tso lawv mus rau hauv lub substrate nto los ntawm vapor deposition los ua ib qho zoo, tawv, thiab cov txheej txheem ruaj khov. Piv nrog rau cov tshuaj vapor deposition (CVD), lub ntsiab zoo ntawm PVD dag nyob rau hauv nws muaj peev xwm mus deposit coatings nyob rau hauv qis kub, precisely tswj txheej thickness thiab muaj pes tsawg leeg, thiab nws environmentally friendly thiab lub zog-npaum xwm.
No.2 Qhov zoo ntawm PVD hauv Hard Coatings
Vim nws qhov tshwj xeeb zoo, PVD thev naus laus zis tau lees paub dav hauv kev siv cov txheej txheem nyuaj, tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam uas xav tau siab hardness, zoo heev hnav tsis kam, thiab superior corrosion kuj. Cov txiaj ntsig tseem ceeb ntawm PVD txheej txheem suav nrog:
1. Ultra-siab hardness thiab hnav tsis kam
PVD tawv txheej tseem ceeb txhim kho cov khoom tawv tawv. Los ntawm kev tso cov ntaub ntawv xws li TiN (Titanium Nitride), TiAlN (Titanium Aluminium Nitride), thiab CrN (Chromium Nitride), lub hardness ntawm txheej tuaj yeem ncav cuag 25GPa–63GPa lossis siab dua. Cov txheej txheej tawv no zoo txhim kho kev hnav tsis kam, txo qhov kev puas tsuaj, ua kom oxidation tsis kam, thiab txuas ntxiv lub neej kev pab cuam ntawm cov cuab yeej, pwm, thiab lwm yam khoom.
2. Kev ua haujlwm kub-kub zoo heev
PVD coatings muaj qhov ua tau zoo ntawm qhov kub thiab txias, ua rau lawv zoo tagnrho rau cov khoom uas raug kub thiab kev sib txhuam los yog tshuaj lom neeg corrosion. Piv txwv li, TiAlN coatings tsis tsuas yog muab tshwj xeeb hardness tab sis kuj tswj cov txheej txheem stability ntawm siab kub, ua rau lawv lug siv nyob rau hauv tej cuab yeej thiab pwm rau high-temperature machining daim ntaub ntawv.
3. Tsawg Friction Coefficient rau kev txhim kho Machining Efficiency
PVD coatings pab ua kom muaj kev sib txhuam qis qis, txo cov khoom sib txhuam thiab hnav, uas txhim kho kev ua haujlwm zoo thiab qhov zoo. Qhov no yog tshwj xeeb tshaj yog zoo rau precision machining thiab high-ceev txiav txheej txheem.
4. Ib puag ncig phooj ywg thiab muaj txiaj ntsig zoo
Piv nrog rau cov txheej txheem txheej txheem txheej txheem, PVD txheej txheem tsis tas yuav muaj cov tshuaj lom neeg ntau, ua rau nws muaj kev cuam tshuam rau ib puag ncig. Tsis tas li ntawd, PVD txheej txheej cov cuab yeej ua haujlwm ntawm kev ua haujlwm siab, ua kom ceev ceev kom tau raws li qhov xav tau ntau lawm.
No.3 Daim ntawv thov teb ntawm PVD Hard Txheej
PVD Hard Coating tshuab rau cov txheej txheej nyuaj yog siv dav hauv kev lag luam uas xav tau kev ua haujlwm zoo tshaj plaws. Qee qhov kev thov tseem ceeb suav nrog:
1. Cov cuab yeej txiav thiab pwm
Hauv kev tsim cov cuab yeej thiab pwm, tshwj xeeb tshaj yog rau kev txiav cov cuab yeej raug kub thiab kev sib txhuam, PVD coatings ho txhim khu kev hnav tsis kam, corrosion resistance, thiab hardness. TiN coatings feem ntau yog siv rau hauv cov cuab yeej tig, milling cutters, thiab xyaum, thaum TiAlN txheej yog siv dav hauv cov ntawv txiav txiav ceev, zoo heev txhim kho cov cuab yeej txiav kev ua haujlwm thiab kev pabcuam lub neej.
2. Automotive Cheebtsam
Rau automotive engine Cheebtsam xws li lub tog raj kheej, pistons, thiab li qub, PVD txheej txheej muaj zoo heev kub-kub kuj thiab hnav tsis kam, zoo txo kev sib txhuam, ncua kev tiv thaiv lub neej, thiab txhim kho tag nrho lub tsheb kev ua tau zoo.
4. Taw qhia ntawm Zhenhua FMA0605 PVD Hard Txheej Khoom
Cov cuab yeej zoo
Kev pom zoo ntawm arc macro-particles; Ta-C coatings muab ob qho tib si kev ua haujlwm siab thiab kev ua haujlwm zoo dua.
