Kuvura Ubuso bwa Aluminium: 7 Urukurikirane rwa Aluminium Ikomeye Anodizing

1. Incamake y'ibikorwa

Anodizing ikomeye ikoresha electrolyte ijyanye na alloy (nka acide sulfurike, aside chromic, aside oxyde, nibindi) nka anode, kandi ikora electrolysis mubihe bimwe na bimwe ikoreshwa nubu. Ubunini bwa firime ikomeye ni 25-150um. Filime ikomeye ya anodize ifite uburebure bwa firime munsi ya 25um ikoreshwa cyane mubice nkimfunguzo zinyo na spiral. Ubunini bwa firime nyinshi zidakenewe birasabwa kuba 50-80um. Kwambara-kwihanganira cyangwa ubunini bwa firime ya anodize kugirango ikingire ni 50um. Mubihe bimwe byihariye bidasanzwe, birasabwa kandi gukora firime zikomeye kandi zifite uburebure burenga 125um. Ariko, twakagombye kumenya ko ubunini bwa firime ya anodize, niko microhardness yikigero cyayo cyo hasi izagabanuka, kandi nubuso bwubuso bwa firime buziyongera.

2. Ibiranga inzira

1) Ubuso bwubuso bwa aluminiyumu nyuma yo anodizing irashobora kugera kuri HV500;

2) Ubunini bwa firime ya Anodic: micron 25-150;

3) Kwizirika gukomeye, ukurikije imiterere ya anodizing iterwa na anodizing ikomeye: 50% ya firime yakozwe ya anodizing yinjira imbere muri aluminiyumu, naho 50% ifata hejuru yubuso bwa aluminiyumu (gukura byerekezo);

4) Gukingira neza: voltage yameneka irashobora kugera 2000V;

5) Kurwanya kwambara neza: Kuri aluminiyumu ivanze n'umuringa uri munsi ya 2%, igipimo ntarengwa cyo kwambara ni 3.5mg / 1000 rpm. Iyerekana ryimyenda yandi mavuta yose ntigomba kurenza 1.5mg / 1000 rpm.

6) Ntabwo ari uburozi kandi butagira ingaruka kumubiri wabantu. Inzira y'amashanyarazi yo kuvura firime ikoreshwa mu gukora ntacyo itwaye, bityo rero kubisabwa kurengera ibidukikije mubikorwa byinshi byo gutunganya imashini zinganda, ibicuruzwa bimwe na bimwe bifashisha aluminiyumu ikomeye cyane aho gukoresha ibyuma bitagira umwanda, gutera imiti gakondo, gufata chromium ikomeye nibindi bikorwa.

3. Imirima yo gusaba

Gukoresha anodizing bikwiranye cyane cyane nibice bisaba kwihanganira kwambara cyane, kurwanya ubushyuhe, hamwe nibintu byiza byo kubika ibice bya aluminium na aluminium. Nka silinderi zitandukanye, piston, indangagaciro, ibyuma bya silinderi, ibyuma, indege zipakurura indege, inkoni zihengamye hamwe na gari ya moshi ziyobora, ibikoresho bya hydraulic, ibyuma byangiza, imashini nziza zometseho, ibyuma na bufferi, nibindi. igiciro, ariko inenge yiyi firime nuko iyo ubunini bwa firime ari bunini, bigira ingaruka kubyihanganira imbaraga zumunaniro ukabije wa aluminium na aluminium.
