Nqus Evaporation Txheej Technology ntawm Nqus Electroplating Hluav Taws Xob Hluav Taws Xob Tube

Nqus evaporation (Nqus evaporation) Txheej yog siv lub evaporator kom sov cov khoom evaporated nyob rau hauv lub tshuab nqus tsev tej yam kev mob rau sublime nws, thiab cov evaporated particle kwj yog ncaj qha mus rau lub substrate, thiab muab tso rau ntawm lub substrate los tsim ib tug khoom zaj duab xis, los yog ib tug evaporated particle kwj yog ncaj qha mus rau lub substrate. nqus txheej ntawm cua sov thiab evaporating cov khoom txheej. txoj kev. Nws cov txheej txheem lub cev yog: hloov nws mus rau hauv lub zog hluav taws xob siv ntau txoj kev siv hluav taws xob, ua kom sov cov khoom plating kom evaporate los yog sublime, thiab ua cov pa roj carbon monoxide (atoms, molecules lossis atomic pawg) nrog qee lub zog ({{0}}} .1~0.3eV); Lub gaseous hais nrog ib tug kuj txav ceev yog thauj mus rau saum npoo ntawm substrate nyob rau hauv ib tug ntau yam sib tsoo-dawb ncaj davhlau; gaseous hais txog qhov chaw ntawm lub substrate condense, nucleate thiab loj hlob mus rau hauv ib tug solid-theem zaj duab xis; cov atoms constituting zaj duab xis yog reorganized thiab teem los yog chemically bonded.

Puas yog lub tshuab nqus tsev electroplating hluav taws xob cua sov raj PVD tsuas yog electroplating?

PVD txheej yog tias cov yeeb yaj kiab tau npaj muaj qhov zoo ntawm qhov siab hardness, tsis tshua muaj kev sib txhuam coefficient, zoo hnav tsis kam thiab tshuaj lom neeg ruaj khov. Cathodic arcing yog ib txoj hauv kev zoo tshaj plaws hauv PVD txheej tshuab. Arc evaporation yog siv los ua kom cov cheeb tsam loj ntawm lub hom phiaj siab heev evaporated thiab ionized. Ua ke nrog cov khoom siv hluav taws xob tuaj rau hauv txoj kev tswj tau, nws tau tso rau hauv titanium nitride TiN, titanium carbonitride TiCN, titanium aluminium nitride AlTiN, thiab chromium nitride. CrN thiab lwm yam txheej txheej. Cov txheej txheem PVD txheej txheej tshuab yog siv rau txheej txheej ntawm ntau cov khoom siv kho vajtse, yas, tuag-casting pwm, riam cuab yeej thiab cov khoom siv precision.

Qhov saum npoo ntawm PVD txheej yog nyias nyias ({0}}µm) cermet txheej, uas tshwj xeeb txhim kho lub zog ntawm txheej txheej thiab hnav tsis kam ntawm txheej txheej, feem ntau yog rau kev sib txhuam, yog li lub zog ntawm lub substrate. tseem ceeb heev. ntawm. Qhov kub xav tau rau stamping tuag yog siab dua 55 degree, thiab qhov kub yuav tsum tau rau cov pwm yas yog siab tshaj 30 degree. Yog hais tias lub zog ntawm lub stamping tuag tsis ncav cuag HRc60 los yog ntau tshaj, lub matrix yuav zoo li "tofu", uas yuav ua rau cov yas deformation tam sim ntawd. Vim li no, lub zog ntawm substrate yuav tsis raug txo vim yog siv cov txheej txheem.
