Taw qhia rau 5 yam tseem ceeb ntawm anodized zaj duab xis

1. Hardness ntawm anodized zaj duab xis

Lub hardness ntawm aluminium thiab aluminium alloy anodized coatings muaj feem xyuam rau cov alloy muaj pes tsawg leeg, anodizing txoj kev, thiab cov txheej txheem specifications. Lub hardness ntawm oxide zaj duab xis nyob ze ntawm lub hauv paus hlau yog siab dua li ntawm txheej txheej oxide zaj duab xis. Nyob rau tib lub sijhawm anodizing, lub hardness ntawm ntshiab aluminium oxide zaj duab xis yog siab dua li ntawm aluminium alloy oxide zaj duab xis.

2. Rwb thaiv tsev ntawm Anodic Oxide Zaj duab xis

Anodic oxide zaj duab xis yog feem ntau tsis-conductive thiab muaj zoo rwb thaiv tsev zog. Thaum qhov kub thiab txias yog 5-25 degree, qhov tsis kam yog 03 Ω / ㎡, thiab thaum qhov kub thiab txias yog 250 degree, qhov tsis kam yog 07 Ω / ㎡. Piv nrog rau lwm cov ntaub ntawv rwb thaiv tsev, siv oxide zaj duab xis raws li cov khoom siv rwb thaiv tsev muaj nws cov yam ntxwv tshwj xeeb, xws li nyias oxide zaj duab xis, kub tsis kam, thiab tiv thaiv corrosion los ntawm dej vapor thiab lwm yam corrosive gases. Qhov tsis zoo yog tsis muaj elasticity, siab noo noo nqus, thiab tsis tshua muaj hluav taws xob tsis kam.

3. Tshuaj stability ntawm anodized zaj duab xis

Anodized oxide zaj duab xis muaj tshuaj lom neeg ruaj khov thiab siab corrosion kuj. Cov oxide zaj duab xis tau los ntawm txoj kev oxidation zoo tib yam yog siv rau cov txheej txheem tiv thaiv saum npoo ntawm txhuas thiab txhuas alloy qhov chaw. Kev tiv thaiv muaj peev xwm ntawm oxide zaj duab xis nyob ntawm nws qhov tuab, qib ntawm porosity, thiab cov alloy muaj pes tsawg leeg ntawm lub hauv paus hlau. Lub corrosion kuj ntawm ntshiab txhuas los yog oxide films coated nrog ntshiab txhuas cov ntaub ntawv yog superior rau cov aluminium alloys. Vim tias aluminium alloys muaj cov hlau uas tsis tsim oxide zaj duab xis, lawv cov corrosion kuj raug txo.

4. Lub Porosity ntawm Anodic Oxide Films

Anodic oxide films yog ntxeem tau thiab muaj peev xwm adsorption siab, uas muaj peev xwm adsorb ntau yam dyes, ntsev, lubricants, waxes, qhuav roj, resins, thiab lwm yam. Oxidized qhov chaw tuaj yeem dyed rau hauv ntau xim rau kev kho kom zoo nkauj, xws li feem ntau siv cwj mem kaus mom, luam yeeb. thawv, ntau yam txhuas phaj, thiab lwm yam. Yog hais tias cov oxide zaj duab xis adsorbs photosensitive agents, nws yuav siv tau los ua cov qauv thiab dials rau cov twj paj nruag. Lub hom phiaj ntawm kev sau cov roj nplua nyeem nrog oxide zaj duab xis yog txhawm rau ua kom hnav tsis kam thiab txo kev sib txhuam coefficient. Siv cov tshuaj paraffin, roj qhuav, thiab cov resin los sau cov pores ntawm oxide zaj duab xis tuaj yeem txhim kho corrosion thiab rwb thaiv tsev.

5. Lub adhesion ntawm anodic oxide zaj duab xis

Cov oxide zaj duab xis yog ncaj qha tsim los ntawm lub hauv paus hlau thiab ruaj khov rau hauv lub hauv paus hlau, ua rau nws nyuaj rau tev tawm ntawm lub hauv paus hlau siv cov cuab yeej siv tshuab. Tom qab oxidation, cov ntawv hlau yog khoov kom txog thaum lawv tawg, thiab cov oxide zaj duab xis tseem nyob ntawm cov hlau. Los ntawm qhov kev pom no, qhov adhesion yog ntau dua li cov txheej txheem. Txawm li cas los xij, vim tias cov oxide zaj duab xis brittleness, qhov chaw uas tau txais kev kho mob oxidation, thaum muaj kev cuam tshuam loj thiab khoov deformations, oxide zaj duab xis ua ntej tawg hauv ib qho mesh zoo li, txo cov ductility thiab tiv thaiv lub peev xwm ntawm lub hauv paus hlau. . Yog li ntawd, qhov chaw uas tau kho oxidation tsis tuaj yeem tiv taus siab thiab deformation.
