I-Aluminium Alloy Surface Treatment: I-7 Series Aluminium Hard Anodizing

1. Uhlolojikelele Lwenqubo

I-anodizing eqinile isebenzisa i-electrolyte ehambisanayo yengxubevange (njenge-sulfuric acid, i-chromic acid, i-oxalic acid, njll.) njenge-anode, futhi yenza i-electrolysis ngaphansi kwezimo ezithile kanye nesimanje esisetshenziswayo. Ubukhulu befilimu ye-anodized eqinile yi-25-150um. Amafilimu ane-anodized aqinile anogqinsi lwefilimu olungaphansi kuka-25um asetshenziswa kakhulu ezingxenyeni ezinjengokhiye bezinyo nama-spirals. Ubukhulu bamafilimu amaningi ane-anodized aqinile buyadingeka ukuthi bube ngu-50-80um. Ingagugi noma ukujiya kwefilimu ene-anodized ukuze kufakwe i-insulation cishe ku-50um. Ngaphansi kwezimo ezithile zenqubo ekhethekile, kuyadingeka futhi ukukhiqiza amafilimu ane-anodized aqinile anogqinsi olungaphezu kuka-125um. Kodwa-ke, kufanele kuqashelwe ukuthi ukuqina kwefilimu ye-anodized, i-microhardness yongqimba yayo yangaphandle izoba phansi, futhi ukugoqa okuphezulu kwesendlalelo sefilimu kuzokwanda.

2. Izici zenqubo

1) Ukuqina kobuso be-aluminium alloy ngemuva kwe-anodizing eqinile bungafinyelela cishe ku-HV500;

2) Ukujiya kwefilimu ye-Anodic oxide: 25-150 microns;

I-3) Ukunamathela okuqinile, ngokusho kwezici ze-anodizing ezikhiqizwa yi-anodizing eqinile: i-50% yefilimu ekhiqiziwe ye-anodizing ingena ngaphakathi kwe-aluminium alloy, futhi i-50% inamathela ebusweni be-aluminium alloy (ukukhula kwe-bidirectional);

4) Ukufakwa okuhle: i-voltage yokuwohloka ingafinyelela ku-2000V;

I-5) Ukumelana nokugqoka okuhle: Kuma-alloys e-aluminium anokuqukethwe kwethusi okungaphansi kuka-2%, inkomba yokugqoka ephezulu yi-3.5mg/1000 rpm. Inkomba yokugqoka yawo wonke amanye ama-alloys akufanele idlule i-1.5mg/1000 rpm.

I-6) Ayinabuthi futhi ayinabungozi emzimbeni womuntu. Inqubo ye-electrochemical yokwelashwa kwefilimu ye-anodizing esetshenziselwa ukukhiqizwa ayinabungozi, ngakho-ke ngezidingo zokuvikela imvelo emishinini eminingi yezimboni, eminye imikhiqizo isebenzisa i-aluminiyamu eqinile anodized esikhundleni sensimbi engagqwali, isifutho sendabuko, i-chromium plating nezinye izinqubo.

3. Izinkambu zokufaka isicelo

I-anodizing eqinile ifaneleka kakhulu ezindaweni ezidinga ukumelana nokushisa okuphezulu, ukumelana nokushisa, kanye nezakhiwo ezinhle zokufakwa kwe-aluminium ne-aluminium alloy. Okufana namasilinda ahlukahlukene, amaphistoni, amavalvu, ama-cylinder liners, amabhere, amagumbi omthwalo wendiza, izinti ezitshekile nama-guide rails, okokusebenza okudonsa amanzi, iziqhumane zesitimu, imishini enethezekile ene-flatbed, amagiya namabhafa, njll. I-electroplating yendabuko ye-chromium eqinile inezici eziphansi. izindleko, kodwa iphutha lale filimu ukuthi lapho ubukhulu befilimu bukhulu, buthinta ukubekezelelana kwemishini. amandla okukhathala kwe-aluminium ne-aluminium alloys.
