Wakiilka Gudbinta Chromium-free ee aluminiumka

S: Alaabooyinka waxay u baahan yihiin inay nadiifiyaan saliidda dusha sare iyo wasakh ka hor inta aan la dhaafin
A: Sababtoo ah sheyga ku jira habka machining (sawir siligga, polishing, iwm.) , saliid qaar ka mid ah iyo wasakh ku dheggan dusha alaabta.Waa in la nadiifiyaa smudginess this ka hor passivation, sababtoo ah this smudginess in dusha alaabta waxay ka hortagi doontaa falcelinta dareeraha passivation, oo waxay saamayn doontaa muuqaalka kore ee saamaynta passivation iyo tayada alaabta.
S: Alaabooyinka marka loo baahan yahay in la qaato farsamada baabuurka ee pickling?
A: Alaabooyinka ku jira habka alxanka iyo daaweynta kulaylka (Si loo kordhiyo adkaanta alaabta, sida habka daaweynta kulaylka ee birta birta ah ee martensitic). oxides waxay saameyn doontaa muuqaalka tayada alaabta, markaa waa inay ka saartaa oksaydhyada dusha sare.

S: Daalaynta korantada waxay leedahay faa'iidooyin marka loo eego polishing farsamada,
A: Waxay noqon kartaa wax soo saarka ballaaran, ka duwan yahay polishing farsamo macmal ah, kaliya kaliya polishing midba midka kale ka dib.Waqtiga shaqadu waa gaaban yahay, wax soo saarka sare.Qiimaha waa yar yahay.Electrolysis ka dib, wasakh dusha sare ah oo sahlan in la nadiifiyo, way ka duwan tahay nadiifinta farsamada macmalka ah, waxaa jiri doona lakabka wax-soo-saarka ee dusha alaabta, ma fududa in la nadiifiyo.Waxaa lagu gaari karaa saamaynta dhalaalaysa muraayadda, oo ay sameeyaan xuub passivation iska caabin daxalka.Waxay si wax ku ool ah u wanaajin kartaa waxqabadka ka hortagga miridhku ee alaabta
