Aluminium Alloy Surface Treatment: 7 Series Aluminium Hard Anodizing

1. Tlhaloso ea Ts'ebetso

Hard anodizing e sebelisa electrolyte e tsamaisanang ea motsoako (joalo ka sulfuric acid, chromic acid, oxalic acid, joalo-joalo) e le anode, 'me e etsa electrolysis tlas'a maemo a itseng le ho sebelisoa hona joale. Botenya ba filimi e thata ea anodized ke 25-150um. Lifilimi tse thata tsa anodized tse nang le botenya ba filimi e ka tlase ho 25um li sebelisoa haholo bakeng sa likarolo tse kang linotlolo tsa meno le li-spirals. Botenya ba lifilimi tse thata ka ho fetisisa tsa anodized bo hlokeha ho ba 50-80um. E thibelang ho roala kapa botenya ba filimi ea anodized bakeng sa ho kenya letsoho e ka ba 50um. Tlas'a maemo a itseng a khethehileng, ho boetse hoa hlokahala ho hlahisa lifilimi tse thata tsa anodized tse nang le botenya bo fetang 125um. Leha ho le joalo, hoa lokela ho hlokomeloa hore filimi e nang le anodized e teteaneng, e ka tlaase ho microhardness ea lera la eona le ka ntle, 'me bokaholimo ba karolo ea filimi bo tla eketseha.

2. Litšobotsi tsa ts'ebetso

1) Ho thatafala ha bokaholimo ba motsoako oa aluminium ka mor'a hore anodizing e thata e ka fihla ho HV500;

2) Anodic oxide filimi botenya: 25-150 microns;

3) Ho khomarela ka matla, ho latela litšoaneleho tsa anodizing tse hlahisoang ke anodizing ka thata: 50% ea filimi e hlahisoang ea anodizing e kenella ka hare ho motsoako oa aluminium, 'me 50% e khomarela holim'a motsoako oa aluminium (kholo ea bidirectional);

4) Insulation e ntle: matla a ho senya a ka fihla ho 2000V;

5) Ho hanyetsa ho apara hantle: Bakeng sa li-alloys tsa aluminium tse nang le koporo e ka tlaase ho 2%, palo e kholo ea ho apara ke 3.5mg / 1000 rpm. Lenane la ho roala la li-alloys tse ling kaofela ha lea lokela ho feta 1.5mg/1000 rpm.

6) Ha e na chefo ebile e se kotsi 'meleng oa motho. Mokhoa oa electrochemical oa phekolo ea filimi ea anodizing e sebelisetsoang tlhahiso ha e na kotsi, kahoo bakeng sa litlhoko tsa ts'ireletso ea tikoloho mecheng e mengata ea liindasteri, lihlahisoa tse ling li sebelisa motsoako o thata oa anodized aluminium ho e-na le tšepe e sa hloekang, ho fafatsa ka setso, ho pata ka chromium ka thata le mekhoa e meng.

3. Libaka tsa kopo

Li-anodizing tse thata li loketse haholo libaka tse hlokang ho hanyetsa mocheso o phahameng, ho hanyetsa mocheso, le thepa e ntle ea ho kenya letsoho ea likarolo tsa aluminium le aluminium alloy. Tse kang li-cylinders tse fapa-fapaneng, li-piston, li-valve, li-cylinder liner, li-bearings, likarolo tsa thepa ea lifofane, lithupa tse sekamang le liporo tsa tataiso, lisebelisoa tsa hydraulic, li-impellers tsa mouoane, mechine e ntle ea flatbed, likere le li-buffer, joalo-joalo. litšenyehelo, empa sekoli sa filimi ena ke hore ha botenya ba filimi bo le boholo, bo ama mamello ea mechine. matla a mokhathala a aluminium le li-alloys tsa aluminium.
