Aluminum Alloy Surface Jiyya: 7 Series Aluminum Hard Anodizing

1. Bayanin Tsari

Hard anodizing yana amfani da daidaitaccen electrolyte na gami (kamar sulfuric acid, chromic acid, oxalic acid, da sauransu) azaman anode, kuma yana yin electrolysis ƙarƙashin wasu yanayi da amfani da halin yanzu. A kauri daga cikin m anodized fim ne 25-150um. Hard anodized fina-finai tare da fim kasa da 25um kauri yawanci amfani da sassa kamar makullin hakori da karkace. Ana buƙatar kauri daga cikin mafi wuyan anodized fina-finai don zama 50-80um. Wear-resistant ko kauri daga cikin anodized fim don rufi ne game da 50um. A ƙarƙashin wasu yanayi na musamman na musamman, ana kuma buƙatar samar da fina-finai masu ƙarfi na anodized tare da kauri fiye da 125um. Duk da haka, dole ne a lura da cewa lokacin da fim din anodized ya fi girma, ƙananan ƙananan ƙananan ƙananan Layer na waje za su kasance, kuma yanayin fuskar fim ɗin zai karu.

2. Halayen tsari

1) A surface taurin aluminum gami bayan wuya anodizing iya isa har zuwa game da HV500;

2) Anodic oxide fim kauri: 25-150 microns;

3) Ƙarfin mannewa, bisa ga halayen anodizing da aka haifar ta hanyar anodizing mai wuya: 50% na fim din da aka samar da shi ya shiga cikin aluminum gami, kuma 50% yana manne da farfajiyar aluminum gami (bidirectional girma);

4) Kyakkyawan rufi: raguwar ƙarfin lantarki zai iya kaiwa 2000V;

5) Kyakkyawan juriya mai kyau: Don aluminium alloys tare da abun ciki na jan karfe na ƙasa da 2%, matsakaicin lalacewa shine 3.5mg / 1000 rpm. Matsakaicin lalacewa na duk sauran gami kada ya wuce 1.5mg/1000 rpm.

6) Mara guba kuma mara lahani ga jikin mutum. Tsarin electrochemical na maganin fim din anodizing da aka yi amfani da shi don samarwa ba shi da lahani, don haka don bukatun kare muhalli a yawancin kayan aikin masana'antu, wasu samfurori suna amfani da aluminum anodized aluminum gami da bakin karfe, feshin gargajiya, chromium plating da sauran matakai.

3. Filayen aikace-aikace

Hard anodizing ya fi dacewa da wuraren da ke buƙatar juriya mai girma, juriya mai zafi, da kyawawan kaddarorin kayan kwalliya na aluminum da aluminum gami sassa. Kamar daban-daban cylinders, pistons, bawuloli, Silinda liners, bearings, jirgin kaya compartments, karkatar sanduna da jagora dogo, na'ura mai aiki da karfin ruwa kayan aiki, tururi impellers, dadi flatbed inji, gears da buffers, da dai sauransu Traditional electroplating na wuya chromium yana da halaye na low farashi, amma lahani na wannan fim shine lokacin da kauri na fim ya yi girma, yana rinjayar juriyar ƙarfin gajiyar inji na aluminum da aluminum gami.
