Aluminiyam ingxubevange Surface Unyango: 7 Series Aluminiyam Hard Anodizing

1. Isishwankathelo seNkqubo

I-anodizing enzima isebenzisa i-electrolyte ehambelanayo ye-alloy (efana ne-sulfuric acid, i-chromic acid, i-oxalic acid, njl.) njenge-anode, kwaye yenza i-electrolysis phantsi kweemeko ezithile kwaye isetyenziswe ngoku. Ubunzima befilimu enzima ye-anodized yi-25-150um. Iifilim ezinobunzima befilimu obungaphantsi kwe-25um zisetyenziswa ikakhulu kwiindawo ezifana nezitshixo zezinyo kunye ne-spirals. Ubunzima beefilimu ezininzi ezinobunzima bufuneka ukuba bube yi-50-80um. Ukumelana nokunxiba okanye ubukhulu befilimu ye-anodized yokugquma malunga ne-50um. Ngaphantsi kweemeko ezithile zenkqubo ekhethekileyo, kuyafuneka kwakhona ukuvelisa iifilimu ezinobunzima obungaphezu kwe-125um. Nangona kunjalo, kufuneka kuqatshelwe ukuba ubuninzi befilimu ye-anodized, i-microhardness yomgangatho wayo wangaphandle iya kuba, kunye nobunzima bomgangatho wefilimu buya kwanda.

2. Iimpawu zenkqubo

1) Ukuqina komphezulu we-aluminium alloy emva kwe-anodizing enzima inokufikelela malunga ne-HV500;

2) Ubukhulu befilimu ye-Anodic oxide: i-25-150 microns;

3) Ukubambelela okuqinileyo, ngokweempawu ze-anodizing eziveliswa yi-anodizing enzima: i-50% yefilimu ye-anodizing eyenziwe ingena ngaphakathi kwe-aluminium alloy, kwaye i-50% ibambelela kumphezulu we-aluminium alloy (ukukhula kwe-bidirectional);

4) Ukufakelwa kakuhle: i-voltage yokuqhawula ingafikelela kwi-2000V;

I-5) Ukuxhatshazwa kakuhle kokugqoka: Kwi-alloys ye-aluminium enomxholo wethusi ongaphantsi kwe-2%, isalathisi esiphezulu sokugqoka i-3.5mg / 1000 rpm. Isalathisi sokunxiba sazo zonke ezinye i-alloys akufanele idlule i-1.5mg / 1000 rpm.

6) Ayinatyhefu kwaye ayinabungozi kumzimba womntu. Inkqubo ye-electrochemical ye-anodizing unyango lwefilimu esetyenziselwa ukuveliswa ayinabungozi, ngoko kwiimfuno zokukhusela indalo kumashishini amaninzi omatshini, ezinye iimveliso zisebenzisa i-aluminiyam i-anodized alloy endaweni yensimbi engenasici, ukutshiza kwendabuko, i-chromium plating kunye nezinye iinkqubo.

3. Iinkalo zesicelo

I-anodizing enzima ifaneleka ikakhulu kwiindawo ezifuna ukumelana nokunxiba okuphezulu, ukumelana nobushushu, kunye neepropathi ezilungileyo zokugquma kwe-aluminiyam kunye ne-aluminium alloy parts. Njengeesilinda ezahlukeneyo, iipistoni, iivalvu, ii-cylinder liners, iibheringi, amagumbi omthwalo wenqwelo-moya, iintonga ezithambekileyo kunye neentsimbi zesikhokelo, izixhobo zehydraulic, ii-impellers zomphunga, oomatshini abatofotofo be-flatbed, iigiya kunye nezithinteli, njl. njl. iindleko, kodwa isiphene sale filimu kukuba xa ubukhulu befilimu bukhulu, buchaphazela ukunyamezela kwamandla okudinwa koomatshini be-aluminium kunye ne-aluminium alloys.
