Mataki na farko: surface pretreatment na aluminum disc da'irar
Mataki na farko shine muhimmin mataki na wafers na aluminum, kuma don anodizing aluminum disc da'irori, wannan mataki yana ƙayyade ƙimar ƙarewa da bayyanar ƙarshe na ɓangaren anodized. Waɗannan sun haɗa da kawar da gurɓataccen abu kamar datti da maiko a saman da'irar diski na aluminum, wanda zai iya hana kawar da ƙananan lahani a saman. Za'a iya aiwatar da hanyoyin sinadarai ko injina azaman jiyya ta riga-kafi.
Mataki 2: Chemical pretreatment na aluminum disc da'irar
Maganin sinadarai galibi yana amfani da magunguna iri-iri don cire datti da maiko (ta hanyar tsabtace acid ko alkaline) da kuma saman oxides da zafi-ma'auni (deoxidizers), wanda ke da wahalar tsaftacewa sosai. Bayan haka, Ana yin wani mataki na etching ko haskakawa don gyara yanayin yanayin, yana haifar da bayyanar musamman. Wannan ya ƙunshi matakai guda biyu na aiki, ɗaya shine ƙirƙirar ƙasa mai sheƙi ko kuma gama saman matte ta matakin etching. Wannan mataki yana cire wani nau'i na uniform daga saman ɓangaren aluminum, don haka rage ƙananan lahani na sama. Ana yin etching ta hanyar tsoma sashin a cikin zafi sodium hydroxide ko trisodium phosphate (alkali etching) ko maganin ruwa na ammonium bifluoride (acidic etching).
Mataki 3: Aluminum diski da'irar inji pretreatment
Bugu da kari ga saman da kuma sinadaran magani na aluminum wafers, Ana buƙatar pretreatment na injiniya na ƙarshe. Ya haɗa da hanyoyin kamar goge goge baki, fashewar yashi, da harbi leƙen asiri. Manufar mataki na ƙarshe shine yafi inganta juriya ga gajiya, taurin, da kuma shafi mannewa na aluminum sassa. Kyakkyawan mannewa na da'irar diski na aluminum yana da mahimmanci don kwanciyar hankali na rufi.
