Automotive qhov chaw kho mob yog hais txog cov txheej txheem ntawm kev kho cov hlau ntau thiab cov yas me me los txhim kho lawv cov corrosion kuj, hnav tsis kam, thiab zoo nkauj, yog li ua tau raws li cov neeg siv khoom xav tau. Nrog rau kev txhim kho txuas ntxiv ntawm cov cuab yeej kho mob saum npoo av, txoj hauv kev kho tsheb qhov chaw kuj tau ua kom muaj txiaj ntsig tas li. Tam sim no, muaj tsib txoj hauv kev tseem ceeb: kev kho electrochemical, txheej txheej, tshuaj lom neeg, kev kho cua sov, thiab cov txheej txheem nqus tsev.
Txoj kev loj hlob keeb kwm ntawm lub tsheb qhov chaw kho mob ntog kev lag luam yog ze ze rau cov evolution thiab technological kev vam meej ntawm lub automotive kev lag luam. Cov thev naus laus zis kho mob thaum ntxov yog qhov yooj yim, feem ntau tsom rau kev tiv thaiv xeb thiab kho kom zoo nkauj, xws li xim txheej, los tiv thaiv cov hlau tsis zoo los ntawm corrosion. Nrog rau txoj kev loj hlob ntawm kev lag luam automotive thiab cov neeg siv khoom xav tau ntau dua rau kev ua haujlwm ntawm tsheb, kev zoo nkauj, thiab ua haujlwm ntev, kev kho cov thev naus laus zis maj mam sib txawv thiab ua ntau yam. Nyob rau hauv nruab nrab-20th caug xyoo, daim ntawv thov dav siv tshuab electroplating cim ib qho kev nce qib hauv kev lag luam kho qhov chaw, tsis yog tsuas yog txhim kho corrosion kuj ntawm qhov chaw tab sis kuj txhim kho lawv cov tsos.
Tom qab ntawd, cov kev taw qhia ntawm technologies xws li electroless plating thiab phosphating ntxiv enriched nto kev kho mob txoj kev, nteg lub hauv paus rau kev txhim kho cov hnav tsis kam, corrosion kuj, thiab qaug zog tsis kam ntawm automotive qhov chaw. Nkag mus rau lub xyoo pua 21st, nrog cov kev cai ib puag ncig nruj zuj zus thiab kev txhawb nqa lub teeb yuag thiab kev txawj ntse tsheb, cov khoom siv hauv tsheb kho qhov chaw kho mob tau coj mus rau lub sijhawm tshiab ntawm kev hloov pauv. Environmentally friendly coatings, xws li dej-raws li cov xim thiab hmoov txheej, tau pib hloov cov tshuaj hnyav ib txwm siv-raws li txheej los txo cov volatile organic compound (VOC) emissions. Nyob rau tib lub sijhawm, kev nce siab ntawm cov thev naus laus zis kho mob xws li lub cev vapor deposition (PVD), tshuaj vapor deposition (CVD), thiab plasma spraying tsis tau tsuas yog txhim kho lub hardness thiab kub tsis kam ntawm coatings tab sis kuj enabled functional deg kho mob, xws li txhim kho antistatic thiab tus kheej - tu lub peev xwm, thiab muab kev tiv thaiv xws li cov khoom siv hluav taws xob.
