Aluminium Alloy Surface Treatment: 7 Series Aluminium Yakaoma Anodizing

1. Maitiro Ongororo

Hard anodizing inoshandisa electrolyte inoenderana yealloy (senge sulfuric acid, chromic acid, oxalic acid, nezvimwewo) seanode, uye inoita electrolysis mune mamwe mamiriro uye inoshandiswa ikozvino. Ukobvu hweiyo yakaoma anodized firimu ndeye 25-150um. Mafirimu akaoma anodized ane bhaisikopo rakakora isingasviki 25um anonyanya kushandiswa kune zvikamu zvakaita sekiyi dzezino uye spirals. Ukobvu hwemafirimu akaomesesa anodized anodiwa kuti ave 50-80um. Kupfeka-kusagadzikana kana ukobvu hweanodized firimu rekudzivirira hunosvika 50um. Pasi pemamwe mamiriro akakosha maitiro, zvinodikanwawo kugadzira akaomeswa anodized mafirimu ane ukobvu hunodarika 125um. Nekudaro, zvinofanirwa kucherechedzwa kuti iyo yakakora iyo anodized firimu, iyo yakaderera iyo microhardness yekunze kwayo ichave, uye kushata kwepamusoro kweiyo firimu layer kuchawedzera.

2. Maitiro maitiro

1) Kuoma kwepamusoro kwealuminium alloy mushure mekuoma anodizing kunogona kusvika kusvika paHV500;

2) Anodic oxide firimu ukobvu: 25-150 microns;

3) Kunamatira kwakasimba, maererano neanodizing maitiro anokonzerwa nekuoma anodizing: 50% yefirimu inodizing yakagadzirwa inopinda mukati mealuminium alloy, uye 50% inonamatira kumusoro kwealuminium alloy (bidirectional kukura);

4) Kuchengetedzwa kwakanaka: kuparara kwemagetsi kunogona kusvika 2000V;

5) Kushongedzwa kwakanaka kwekupfeka: Kune aruminiyamu alloys ane mhangura yemukati isingasviki 2%, iyo yakanyanya kupfeka index ndeye 3.5mg / 1000 rpm. Iyo yekupfeka index yemamwe ese alloys haifanire kudarika 1.5mg/1000 rpm.

6) Isiri-chepfu uye isingakuvadzi kumuviri wemunhu. Iyo electrochemical process yeanodizing firimu kurapwa inoshandiswa kugadzirwa haina kukuvadza, saka kune kuchengetedzwa kwezvakatipoteredza zvinodiwa mumaindasitiri mazhinji ekugadzira michina, zvimwe zvigadzirwa zvinoshandisa yakaoma anodized aluminium alloy pachinzvimbo chesimbi isina tsvina, kupfapfaidza kwechinyakare, hard chromium plating uye mamwe maitiro.

3. Minda yekushandisa

Hard anodizing inonyanya kukodzera nzvimbo dzinoda kupfeka kwepamusoro, kuramba kupisa, uye yakanaka insulation zvimiro zvealuminium uye aluminium alloy zvikamu. Senge masilinda akasiyana-siyana, mapiston, mavharuvhu, silinda liners, mabearings, midziyo yekutakura ndege, tsvimbo dzakarereka uye njanji, hydraulic midziyo, steam impellers, yakagadzika flatbed michina, magiya uye mabuffers, etc. Traditional electroplating ye hard chromium ine hunhu hwekudzikira. mutengo, asi kukanganisa kwefirimu iyi ndeyekuti kana iyo firimu yakakura, inokanganisa kushivirira kwemagetsi kuneta simba realuminium nealuminium alloys.
