Pwm TD ua thiab txheej txheem PVD
Jun 15, 2021| Pwm TD ua thiab txheej txheem PVD
1.Kev ua TD thiab PVD kev ua - cov hom txheej txheej txheej tawv 1) TD txheej txheem (thermal diffusion txujci) yog qee qhov kub thiab txias, muab cov pwm hauv borax hauv ntsev ntsev thiab nws cov xov xwm tshwj xeeb, los ntawm cov hlau atoms hauv molten ntsev thiab cov pa roj carbon thiab nitrogen atoms hauv cov pwm uas tsim cov tshuaj lom neeg, kev sib txawv ntawm cov pwm nto, kev tsim cov tawv hlau carbide txheej tuab ntawm ob peb microns. Tam sim no, vanadium carbide (VC) txheej yog siv dav. 2) Kev kho mob PVD (lub cev vapor deposition) yog qhov xau xaim ntawm atoms lossis cov lwg me me uas tau tsim los ntawm ntau lub cev ntawm cov txheej txheem ntawm lub cev ntawm cov txheej hauv qab ntawm lub nqus. PVD kho thev naus laus zis tuaj yeem hloov cov txheej txheem thiab cov khoom siv lub hom phiaj, thiab tom qab ntawd hloov cov qauv thiab cov txheej txheem ntawm cov npoo tawv txheej, siv los npaj ntau yam tshwj xeeb cov tshuab thiab tshuaj (xws li super nyuaj, siab corrosion tsis kam, kub tsis kam, oxidation tsis kam). , nws tus kheej lubricating, thiab lwm yam) txheej, nws daim ntawv thov yog ntau dav. Tam sim no, PVD kho tshuab ntau siv hauv cov pwm yog titanium nitride (TiN), titanium nitride (TiCN), titanium nitride aluminide (TiAlN), chromium nitride (CrN), thiab lwm yam, uas nws qhov nyuaj feem ntau qis dua li ntawm TD txheej vanadium carbide.
2.Kev kho mob TD thiab kev kho PVD - kev ua cov kub, cov khoom siv matrix thiab kev kho kom sov ua ntej 1) Kev kho mob TD yog kev kho kub, qhov kub tshaj 900℃-1050℃, yog li TD kho tshuab yuav muaj qee qhov teeb meem ntawm deformation, tswj tsis zoo yuav tshwm sim tawg. TD kev kho mob ntawm cov khoom siv pwm xav tau muaj ntau dua, feem ntau yuav tsum tau siv kev hloov pauv me me ntawm kev sib xyaw ntawm cov hlau siab, xws li cov khoom siv ntau siab chromium alloy tuag steel Cr2MoV, SKD11, DC53, D2, thiab lwm yam Yuav kom txo cov deformation ntawm kev kho mob TD, nws raug nquahu kom nqa tawm ob qhov kub kub kub tom qab kev kho mob ua ntej. Rau lub pwm nrog kev deformation tsis muaj qis, kev kho TD tuaj yeem nqa tawm ncaj qha yam tsis tau kho ua ntej. 2) PVD thev naus laus zis kev siv tshuab ua ntsuas kub kuj tseem qis, 400℃-600℃, rau lub pwm nws qhov txiaj ntsig zoo tshaj yog qhov workpiece deformation tom qab ua tiav yog qhov ntau me me. Kev kho mob PVD hais tias cov khoom siv mould workpiece tau txias thaum kub. PVD kho ntawm lub hauv paus cov khoom siv yuav tsum muaj siab heev, feem ntau siv yog kev kub ceev steel lossis hmoov siab ceev steel, lossis zoo siab chromium alloy tuag hlau xws li Cr12MoV, SKD11, DC53, D2, thiab lwm yam, yog tias cov khoom siv tsis sib xws los yog qhov muaj pes tsawg leeg tsis dhau ntawm tus qauv, PVD txheej kho tom qab cov nyhuv yog qhov nyuaj rau kev cuam tshuam.
3.Kev kho TD thiab kev kho mob PVD - sib piv ntawm kev sib txuas lub zog ntawm cov txheej tawv tawv thiab lub hauv paus hlau PVD txheej thiab puag hlau zoo ib yam li electroplating, belongs rau cov khoom siv ua ke, kev sib khi thiab cov cuab yeej kho cov khoom kho tau muaj kev sib raug zoo nrog cov theem ntawm cov thev naus laus zis Cov. Txawm hais tias siv lub tshuab thev naus laus zis, TD-kho tawv xim txheej tuaj yeem tiv taus kev ntxhov siab ntau dua li ntawm PVD txheej tsis muaj qhov khoob.
4.Kev kho mob TDD thiab kev kho mob PVD - hlau stamping tuag teb daim ntawv thov thiab kev sib piv cov txiaj ntsig TD kho thiab kev kho PVD tuaj yeem siv los txhim kho lub neej kev tuag thiab daws cov teeb meem ntawm npoo tawv ntawm qhov tuag. Kev kho mob TD tuaj yeem siv rau steel phaj lub zog 590MPa sib sau tuag thiab lwm qhov kev nyuaj siab loj, PVD txheej tuaj yeem siv rau nyias phaj tuab, tsis muaj zog lub sijhawm. Cov pwm nrog qhov siab qhov siab tuaj yeem tsuas yog kho nrog PVD. Hauv ntej, txhawm rau txhim kho lub neej ntawm qhov chaw ua haujlwm tuag, tsim + cov khoom siv xaiv + machining + ua ntej kho cua sov + qhov tsim nyog kho saum npoo, ua cov kauj ruam yog, txhawm rau kom ua tiav lossis dhau tus qauv kev pabcuam lub neej.
