PVD (lub cev vapor deposition): txoj kev siv lub cev (xws li evaporation, sputtering, thiab lwm yam) yog siv los vaporize cov khoom txheej ntawm lub substrate nto thiab tso rau hauv ib txheej txheej.Cov txheej txheem ntawm kev siv cov txheej txheem ntawm lub cev kom paub cov khoom xa mus thiab hloov cov atoms lossis molecules los ntawm qhov chaw mus rau substrate nto.Nws txoj haujlwm yog txhawm rau tshuaj tsuag qee cov khoom uas muaj cov khoom tshwj xeeb (siab zog, hnav tsis kam, kub dissipation, corrosion kuj, thiab lwm yam) ntawm lub matrix nrog kev ua haujlwm qis, kom lub matrix muaj kev ua tau zoo dua.
CVD (tshuaj vapor deposition): ib txoj kev ntawm chemically reacting roj nyob rau saum npoo ntawm matrix khoom thiab tsim ib tug npog txheej.Nws yog cov txheej txheem thev naus laus zis uas cov tshuaj reactive reacts chemically nyob rau hauv gaseous tej yam kev mob los tsim cov khoom, uas yog muab tso rau ntawm lub rhuab khoom matrix nto, thiab ces cov khoom yog npaj.Nws tseem ceeb yog nyob rau hauv cov txheej txheem hloov pauv huab cua hauv pawg atomic.
CVD lossis PVD kuj tseem yog txheej txheej txheej Zoo li npib tsib xee plating, kub plating thiab zinc plating, kev ua haujlwm ntawm txheej yog ua kom hnav tsis kam thiab corrosion kuj.
Qhov sib txawv ntawm PVD thiab CVD:
PVD yog nyias dua li CVD, thiab txheej thickness ntawm CVD yog 10 ~ 20 μ m.Cov txheej thickness ntawm PVD tsuas yog 3 ~ 5 μ M los yog li ntawd.Kev kho kub ntawm PVD yog li 500 ℃, thaum qhov kub ntawm CVD rauv yog 800 ~ 1000 ℃.Nws tuaj yeem pom tau tias vim qhov kub thiab txias, CVD muaj qhov kub thiab txias tsis kam rau cov khoom siv kho mob
CVD yog qhov zoo dua ib puag ncig tus phooj ywg thiab hnav-tiv taus txheej txheej tam sim no.Nws tuaj yeem siv rau hauv ntau qhov chaw, xws li moos thiab saib kev lag luam, kev lag luam kho vajtse, kev lag luam tsheb, kev lag luam catering thiab lwm yam.
Yog tias xav tau CVD lossis PVD hauv CNC machining qhov chaw, thov hu rau peb.Peb tshwj xeeb hauv cnc machining qhov chaw, cnc tig, cnc milling machining, cnc lathing machining, nrog 45 teeb cnc tshuab hauv peb lub rooj cob qhia, suav nrog 3 axis, 4 axis, 5 axis tshuab.
