Muaj rau txoj kev kho oxidation ntawm txhuas profiles feem ntau siv nyob rau hauv kev lag luam, uas yog txoj kev anodizing, electroplating kev kho mob txoj kev, soaking kev kho mob txoj kev, nto txau txoj kev, txhaj tshuaj peening txoj kev kho mob thiab lub tshuab nqus tsev txau txoj kev. hom kev kho deg txoj kev ntawmaluminium profiles.

Txoj kev Anodizing: Anodizing method yog ib txoj hauv kev tsim cov oxide zaj duab xis rau ntawm qhov chaw ua haujlwm lossis cov khoom siv los ntawm kev siv cov txheej txheem electrolysis ntawm cov khoom siv hluav taws xob ncaj qha thiab hloov pauv thiab ncaj qha tam sim no txhawm rau txhawm rau txhim kho corrosion thiab ua kom lub ntsej muag zoo nkauj.

Txoj kev kho electroplating: Txoj kev kho electroplating yog siv cov khoom ua haujlwm raws li cathode thiab cov khoom tsim cov txheej txheem raws li cov anode, muab ob qho tib si rau hauv lub tank nrog cov tshuaj plating, thiab tom qab ntawd siv ncaj qha tam sim no lossis hloov pauv thiab ncaj qha tam sim no rau ionize cov khoom tsim cov txheej. .Thiab khiav los ntawm cov tshuaj electroplating rau saum npoo ntawm lub workpiece, thiab khov kho rau nws los tsim ib txoj kev sib txawv thicknesses.

Txoj kev kho immersion: Ua ntej tshem cov roj stains ntawm cov castings los yog cov khoom uas muaj degreasing kua, thiab ces yaug nrog dej sov ntawm 25 mus rau 30 degrees kom txuag tau tshav kub.Tom qab ntawd muab tso rau hauv lub infiltrator thiab kaw nws nrog ib tug cover, nqus nws mus rau 0.7 mus rau 0.8. Pa, ua kom qhov kub thiab txias nyob ib ncig ntawm 65 degrees, thiab tom qab ntawd txhaj cov tshuaj infiltrant npaj rau hauv infiltrator.Tom qab 8 mus rau 10 teev ntawm so, cov cua compressed qhuav yog qhia kom lub siab nyob rau hauv nws li ntawm 0.4 Pa rau lwm 8 mus rau 10 teev, thiab thaum kawg cov huab cua raug tso tawm kom tshem tawm cov castings los yog cov khoom rau huab cua kom qhuav.

Nto txau txoj kev: Txau cov xim ntawm cov cam khwb cia txhuas qhov chaw lossis cov khoom siv aluminium alloy thiab cov khoom yog los txhim kho lawv cov corrosion kuj.Rau castings los yog cov khoom yuav tsum tau zoo corrosion kuj, aluminium castings los yog cov khoom yuav tsum tau anodized los yog chemically oxidized ua ntej spraying.Re-xim primer, txhuam saum lub tsho tiv no.

Kev txhaj tshuaj peening: muab cov aluminium alloy casting rau hauv lub nruas ntawm lub tshuab txhaj tshuaj peening, thiab tshuaj tsuag nws mus rau saum npoo ntawm casting nrog kev kub ceev txhaj tshuaj ntws.Vim tias cov casting yog tas li flipped tib lub sijhawm.tag nrho nws cov chaw muaj zog los ntawm cov txhaj tshuaj blasting.

Vacuum txau txoj kev: Muab cov khoom los yog cov ntaub ntawv yuav tsum tau txau rau hauv lub tshuab nqus tsev ntawm cov tshuaj tsuag txheej tshuab raws li cov cathode, siv cov khoom tsim cov txheej txheem txau raws li cov anode, kaw lub tshuab nqus tsev vacuum thiab khiav tawm mus rau qee qhov nqus, thiab siv high- Lub hwj chim plasma.Qhov phom sputters thiab tso cov khoom txau rau hauv lub xeev ion ntawm cov khoom lossis profile raws li cathode, tsim ib txheej txheej ntawm ob mus rau kaum microns, qhia ntau yam ci ci.
