7075 aruminiyamu alloy, se7 akateedzana aruminiyamu alloy ane yakakwira zinc content, anoshandiswa zvakanyanya muaerospace, mauto uye epamusoro-yekupedzisira maindasitiri ekugadzira nekuda kweakanakisa ma mechanical zvivakwa uye huremu hunhu. Nekudaro, pane zvimwe zvinonetsa paunenge uchiita kurapwa kwepamusoro, kunyanya kana uchiita anodizing kuti uwedzere kusimba kwayo kwekuora uye kuoma kwepasi.
Anodizing inzira ye electrochemical kuburikidza nayo iyo aluminium oxide firimu inogona kuumbwa pamusoro pesimbi kuti ivandudze kusakara kwayo, kusagadzikana kwekuora uye aesthetics. Nekudaro, nekuda kweiyo yakakwira zinc mu7075 aruminiyamu alloy uye maitiro ekuumbwa kweAl-Zn-Mg alloy, mamwe matambudziko anowanzo kuitika panguva yeanodizing:
1. Ruvara rusina kuenzana:Iyo zinc element ine simba rakakura pane iyo oxidation mhedzisiro, iyo inogona kutungamira kune chena mipendero, mavara matema, uye mavara asina kuenzana pane workpiece mushure meoxidation. Matambudziko aya anonyanya kuoneka paanenge achiedza kuisa oxidize mumavara akajeka (seakatsvuka, orenji, nezvimwewo) nekuti kugadzikana kwemavara aya kunenge kwakashata.
2. Kusakwana kunamatira kweiyo oxide firimu:Kana iyo yechinyakare muitiro we sulfuric acid anodizing inoshandiswa kurapa 7 akatevedzana aruminiyamu alloys, nekuda kwekusaenzana kugovera uye kupatsanurwa kwearuminiyamu alloy zvikamu, ukuru hweiyo micropores pamusoro peiyo oxide firimu ichasiyana zvakanyanya mushure meanodizing. Izvi zvinotungamira kune misiyano yemhando uye kunamatira kweiyo oxide firimu munzvimbo dzakasiyana, uye iyo oxide firimu kune dzimwe nzvimbo ine isina kusimba yekunamatira uye inogona kutodonha.
Kuti ugadzirise matambudziko aya, zvinodikanwa kutora a yakakosha anodizing kana kuvandudza maitiro aripo, sekugadzirisa kuumbwa, tembiricha uye density yezvino ye electrolyte, izvo zvinokanganisa kunaka uye kushanda kweiyo oxide firimu. Semuenzaniso, iyo pH ye electrolyte ichakanganisa chiyero chekukura uye chimiro chepore cheiyo oxide film; iyo density iripo yakanangana nehupamhi uye kuoma kweiyo oxide film. Nekunyatso kudzora ma parameter aya, anodized aruminiyamu firimu rinosangana nezvinodiwa rinogona kugadzirwa.
Maedzo anoratidza kuti mushure mekuzodza iyo 7 yakatevedzana aruminiyamu alloy, iyo oxide firimu ine ukobvu hwe30um-50um inogona kuwanikwa. Iyi oxide firimu haigone kuchengetedza zvinobudirira iyo aluminium alloy substrate uye kuwedzera hupenyu hwayo hwesevhisi, asi zvakare inosangana nezvinodiwa zvekuita nekugadzirisa maitiro paramita. Iyo yepamusoro yealuminium alloy mushure meanodizing inogona zvakare kudhayiwa kuti itore organic kana inorganic pigment kuti ipe iyo aluminium alloy akapfuma mavara kuti asangane akasiyana aesthetic zvinodiwa.
Muchidimbu, anodizing inzira inoshanda yekuvandudza mashandiro e7 akatevedzana aluminium alloys. Nekugadzirisa maitiro ekugadzirisa, firimu rinodzivirira rinosangana nekuoma kwakasiyana uye zvinodiwa zvinogona kugadzirirwa, izvo zvinowedzera zvikuru nzvimbo yekushandisa yealuminium alloys.
