Yuav ua li cas tuab ib txheej tuaj yeem kho cov kab kab ntau lawm?

Kev tswj cov txheej tuab tuab yog qhov ntsuas cov ntsiab lus ntawm cov kab ntau lawm, nrog cov txheej txheem sab saud feem ntau txiav txim siab los ntawm cov yam ntxwv, thiab cov khoom yuav tsum tau ua. Noj cov txheej txheem electroplating ua piv txwv, cov kab ntau lawm ua tau tiav tuaj yeem ua tiav cov txheej txheem txheej txheem ntawm 5 {}} microns. Txawm li cas los xij, los ntawm kev txhim kho cov txheej txheem electrolyte, ntiav cov kab ke sib xyaw ua ke, lossis siv cov kab tshwj xeeb ua tiav tuaj yeem ua tiav cov tuab tshaj 200 microns. Piv txwv li, tawv chrome plating ntawm automotive piston rings, los ntawm ntau ntau tank tsim thiab cathode kev txav, tuaj yeem ua tiav cov txheej txheej ntawm 150-300 microns.

Hauv kev tsim khoom tiag tiag, ua tiav ultra - cov txheej txheem tuab: Ua ntej, cov kev sib zog ua kom zoo dua qub thiab kev hloov pauv ntxiv rau cov kev nce tuab; Thib ob, sab hauv kev ntxhov siab ntxiv. Thaum tuab tshaj tus nqi tseem ceeb, tawg thiab delamination yog tshwm sim, kev tshoov siab siv gradient siv thev naus laus zis / tooj liab / nuppwich cov qauv; Thib peb, kev lag luam txiav txim siab ntawm kev tso nyiaj. For thicknesses exceeding 100 microns, localized strengthening processes such as brush plating or laser cladding are often more cost-effective.

Tshwj xeeb, cov thermal teeb meem txheej txheem txheej txheem siv rau ntawm cov dav hlau cav tuaj yeem ua rau muaj lwm txoj kev siv thev naus laus zis. Los ntawm cov txheej txheem sib xyaw ua ke ntawm vapor deposition thiab electroplating, meej deplitition ntawm cerams txheej ntawm qib yuav ua tau tiav nyob rau hauv ib puag ncig nqus plua plav. Tus ntoo khaub lig no- Kev Qhuab Qhia Technthological nco qab yog nyob ntawm ib qho kev ua ke tshiab tab sis kuj ntawm kev txhim kho kev ua haujlwm ntawm ntau yam kev kho mob. Nrog cov neeg siv cov ntawv thov ntawm atomic txheej tso nyiaj (ALD) thev naus laus zis, ua tiav ob qho tib si nanoscale precision thiab macroscale tuab yuav dhau los ua tau.
