Tsis xav tau kev kho cua sov tom qab lub tshuab nqus tsev plating hluav taws xob cua sov raj txheej
Cov txheej txheej kub (300 ~ 500 degree) yog qis dua qhov kub ntawm cov cuab yeej kub ceev, yog li nws yuav tsis ua rau qhov nyuaj thiab qhov tseeb ntawm cov cuab yeej siv high-speed steel, thiab kev kho cua sov tsis tas yuav tsum tau tom qab txheej. Qhov zoo ntawm cov txheej txheej tsuas yog ob peb microns, yog li thawj qhov tseeb ntawm cov cuab yeej tuaj yeem lav tau, thiab nws tsim nyog rau txheej txheej cov cuab yeej ua haujlwm siab.
Lub purity ntawm lub txheej yog siab, qhov ceev yog zoo, kev sib xyaw ntawm cov txheej thiab cov substrate yog ruaj khov, thiab kev ua tau zoo ntawm cov txheej tsis cuam tshuam los ntawm cov khoom ntawm cov substrate. Cov txheej yog sib xws, thiab tsis muaj thickening los yog rounding ntawm txiav ntug thiab arc, yog li txawm cov cuab yeej complex yuav tsum uniformly coated. Tsis muaj cov txheej txheem decarburization, thiab tsis muaj qhov tawg ntawm cov txheej txheej tshwm sim los ntawm chlorine corrosion thiab hydrogen embrittlement deformation hauv CVD txoj kev, thiab lub zog ntawm cov hniav coated yog siab. Cov txheej txheem ua haujlwm yog huv, tsis muaj kuab lom thiab tsis muaj kuab lom.
Nqus electroplating hluav taws xob cua sov raj MT-CVD coated hniav
TCN coatings nrog ntom fibrous crystalline morphology tuaj yeem tau los ntawm nruab nrab kub tshuaj vapor deposition (MTCVD) ntawm 700 ~ 900 degree, thiab lub thickness ntawm txheej tuaj yeem ncav cuag 8 ~ 10μm, thiab txheej txheej tuaj yeem tso los ntawm CVD technology. Nws muaj qhov kub thiab txias oxidation kev ua tau zoo, tsis tshua muaj affinity nrog cov khoom yuav tsum tau ua, thiab zoo self-lubricating kev ua tau zoo.
MT-CVD coated inserts yog haum rau high-ceev, high-temperature, hnyav-load, qhuav tej yam kev mob, thiab lawv cov kev pab cuam lub neej yuav muab ob npaug rau piv rau zoo tib yam coated inserts. Lub ntsiab tsis zoo ntawm CVD txoj kev yog tias qhov kub ntawm qhov tso tawm yog siab, uas yuav ua rau cov cuab yeej deformation thaum txheej txheej high-speed steel cov cuab yeej. Yog li ntawd, cov cuab yeej tso cia yuav tsum tau quenched.
