Kuoxidation yakaoma pazvigadzirwa zvearuminiyamu ibasa rakakosha rinosimudzira kugara kwenguva refu uye kushanda zvakanaka kwechinhu chacho. Zvigadzirwa zvearuminiyamu zvinoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana nekuda kwekureruka kwazvo, kuramba ngura, uye chiyero chakasimba chekusimba nehuremu. Zvisinei, kuti zviwedzere kuvandudza hunhu hwazvo, oxidation yakaoma inoshandiswa kugadzira layer inodzivirira pamusoro pearuminiyamu. Chinyorwa chino chichaongorora maitiro eoxidation yakaoma pazvigadzirwa zvearuminiyamu, mabhenefiti ayo, uye mashandisirwo ayo mumaindasitiri akasiyana.
Kuoxidation kwakaoma, kunozivikanwawo se hard anodizing, inzira ye electrochemical inoshandura pamusoro pe aluminum alloy kuita gobvu, rakaoma, uye rinodzivirira ngura. Maitiro aya anosanganisira kunyudza chigadzirwa che aluminum alloy mumushonga we electrolyte uye kupfuudza magetsi emagetsi nepakati payo. Mugumisiro wacho kuumbwa kwe dense uye yakasimba oxide layer pamusoro pe aluminum alloy, zvichiwedzera zvakanyanya hunhu hwayo hwemakanika nemakemikari.
Maitiro ekuoxidation yakaoma anowanzo sanganisira matanho akati wandei. Chekutanga, chigadzirwa chealuminium alloy chinocheneswa zvakanaka kubvisa chero tsvina kana tsvina pamusoro. Izvi zvakakosha kuti kuve nechokwadi chekuumbwa kweyunifomu yakafanana uye yepamusoro-soro yeoxide layer. Mushure mekuchenesa, yunifomu yealuminium inonyudzwa mu solution ye acidic electrolyte, senge sulfuric acid, uye inoshanda seanode mu electrolyte circuit. Direct current inozopfuudzwa ne electrolyte, zvichiita kuti oxidation reaction iitike pamusoro peyunifomu yealuminium. Izvi zvinoguma nekuumbwa kweyunifomu yakakora uye yakaoma, iyo inogona kusiyana neruvara kubva kugrey light kusvika kudema, zvichienderana ne process parameters chaiyo uye alloy composition.
Maitiro ekushanda kwe hard oxidation anogona kugadziriswa kuti awane hunhu hwakasiyana zvichienderana nezvinodiwa pakushandisa. Nekugadzirisa ma process parameters akadai se electrolyte composition, tembiricha, uye current density, ukobvu nekuoma kwe oxide layer zvinogona kudzorwa. Kazhinji, hard oxidation inoguma ne oxide layers dzakakora kanoverengeka kupfuura idzo dzinogadzirwa mumaitiro e anodizing, kubva pa 25 kusvika 150 microns. Kuwedzera uku ukobvu kunopa kudzivirira kupfeka kwakanyanya, kuomarara, uye ngura, zvichiita kuti ive yakakodzera kushandiswa munzvimbo dzakaoma.
Chimwe chezvakanakira zvikuru zvekuoxidation yakasimba pazvigadzirwa zvealuminium alloy ndiko kuvandudzika kukuru kwekuoma kwenzvimbo uye kuramba kupfeka. Huru hwakakora uye hwakaoma hweoxide hunoumbwa kuburikidza nemaitiro aya hunosimbisa zvikuru kuramba kwekukwesha kwealuminium alloy, zvichiita kuti ive yakakodzera kushandiswa uko zvinhu zvacho zvinokuvadzwa zvakanyanya. Izvi zvinoita kuti oxidation yakaoma ive mushonga wakanaka wepamusoro wezvinhu zvinoshandiswa mumotokari, mundege, uye mumichina yemaindasitiri, uko kugara kwenguva refu uye kugara kwenguva refu kwakakosha.
Pamusoro pekuomarara uye kusakara kwakawedzerwa, kuomarara kunowedzerawo kuramba kukora kwezvigadzirwa zvealuminium alloy. Gobvu reoxide layer rinoshanda sechidziviriro, richidzivirira alloy iri pasi pealuminium kubva kuzvinhu zvakaita sehunyoro, makemikari, uye munyu. Izvi zvinoita kuti zvigadzirwa zvealuminium alloy zvakaoma zvinyatsokodzera kushandiswa kunze uye mugungwa, uko kusangana nemamiriro ekunze akaoma kunogona kutungamira mukuora uye kuora kwezvinhu.
Uyezve, maitiro ekuoxidation yakaoma anogonawo kuvandudza hunhu hwemagetsi nekupisa hwezvigadzirwa zvealuminium alloy. Dense oxide layer inoshanda sechidziviriro chekudzivirira, zvichiita kuti ive yakakodzera zvikamu zvemagetsi uye mashandisirwo apo kutonga kwekupisa kwakakosha. Izvi zvinoita kuti zvigadzirwa zvealuminium alloy yakaoma oxidized hard oxidized zvive zvakakosha muindasitiri yemagetsi uye semiconductor, uko hunhu hwemagetsi nekupisa hwezvinhu izvi hunonyanya kukosha.
Hunhu hwepamusoro hunowedzerwa hunowanikwa kuburikidza nekuoxidation yakaoma hunobatsirawo mukuvandudza kunamira uye hunhu hwekubatanidza. Izvi zvinoita kuti zvigadzirwa zvealuminium alloy yakaoma oxidized zvikodzere kushandiswa uko machira, manamira, kana maitiro ekubatanidza anoshandiswa. Nzvimbo yakakasharara uye nzvimbo yakawedzerwa yekumusoro inobva mukuita kweoxidation yakaoma zvinopa nzvimbo yakanaka yekusimudzira kunamira kwakasimba, zvichiita kuti machira nemanamira zvinamire zvakasimba kune substrate yealuminium alloy.
Mashandisirwo ezvigadzirwa zve hard oxidized alloy alloy akasiyana-siyana uye anopararira mumaindasitiri akasiyana-siyana. Muchikamu chemotokari, hard oxidation inoshandiswa kuwedzera kugara kwenguva refu uye kuramba kupfeka kwezvinhu zvakaita semapistoni, macylinder, uye zvikamu zveinjini. Indasitiri yendege inobatsirwawo nezvigadzirwa zve hard oxidized alloy alloy, uko kuramba ngura uye hunhu hwekupfeka kwakakosha kune zvikamu zvendege nezvinhu zvekuvaka. Pamusoro pezvo, chikamu chemichina nemidziyo yeindasitiri chinoshandisa zvigadzirwa zve hard oxidized alloy alloy kune zvikamu zvinoremerwa, kukweshana, uye kupfeka zvinorwadza.
Uyezve, indasitiri yezvemugungwa inoshandisa zvakanyanya zvigadzirwa zvealuminium alloy zvakaoma zvemidziyo yemugungwa, zvigadziko, uye zvikamu zvinosangana nemvura yemunyu nenzvimbo dzakaoma dzemugungwa. Maindasitiri emagetsi neemagetsi anoshandisawo zvigadzirwa zvealuminium alloy zvakaoma zvemagetsi, zvigadziko zvekupisa, uye zvikamu zvinoda kuputira magetsi zvakanyanya uye hunhu hwekutarisira kupisa. Uyezve, makambani ezvehutano nehutano anobatsirwa nekushandiswa kwezvigadzirwa zvealuminium alloy zvakaoma zvemidziyo yekuvhiya, zvishandiso zvekurapa, uye michina inoda kuramba kupfeka zvakanyanya uye kubatana kwakasimba.
Mukupedzisa, kuomarara kwesimbi pazvigadzirwa zvealuminium alloy inzira yakakosha yekurapa pamusoro iyo inowedzera hunhu hwemakanika, makemikari, uye magetsi echinhu chacho. Kuumbwa kwechikamu chakakora uye chakaoma cheoxide kuburikidza nekushanda kwehard oxidation kunovandudza zvakanyanya kuramba kwekupfekwa, kuramba ngura, uye hunhu hwekunamatira kwezvigadzirwa zvealuminium alloy. Izvi zvinoita kuti zvigadzirwa zvealuminium alloy zvakaoma zvive zvakakosha mumaindasitiri akasiyana-siyana, anosanganisira mota, ndege, zvegungwa, zvemagetsi, uye hutano. Sezvo tekinoroji ichiramba ichifambira mberi, kudiwa kwezvigadzirwa zvealuminium alloy zvakaoma kunotarisirwa kukura, zvichikonzerwa nekudiwa kwezvinhu zvinoshanda zvakanaka zvinokwanisa kumira mumamiriro ezvinhu akaoma ekushanda.
