Doorashooyinka Kala Duwan ee Daawaynta Kulaylka
Adkeynta:Adkeynta waxaa loo sameeyaa si wax looga qabto cilladaha birta, gaar ahaan kuwa saameeya cimriga guud.Waxaa lagu fuliyaa iyadoo la kululeynayo birta oo si degdeg ah loo demiyo marka ay gaarto hantida la rabo.Tani waxay qaboojisaa qaybaha si ay u hesho tayo cusub.
Xiritaanka:Inta badan aluminium, naxaasta, birta, qalinka ama naxaasta, annealing waxay ku lug leedahay kuleylinta birta heerkul sare, ku hay halkaas oo u oggolaanaysa inay si tartiib ah u qaboojiso.Tani waxay fududaynaysaa in birahan ay u shaqeeyaan qaab ahaan.Naxaasta, qalinka iyo naxaasta si dhakhso ah ama tartiib ah ayaa loo qaboojin karaa, iyadoo ku xidhan codsiga, laakiin birta had iyo jeer waa inay si tartiib tartiib ah u qaboojiso haddii kale si fiican uma tirtiri doonto.Tan waxa caadiyan la fuliyaa ka hor inta aan la farsamayn si aanay agabku u fashilmin inta lagu jiro wax soo saarka.
Caadiyan:Badanaa loo isticmaalo birta, caadi ka dhigista waxay wanaajisaa mashiinada, ductility iyo xoogga.Birtu waxay kulushahay 150 ilaa 200 darajo ka kulul biraha loo isticmaalo habsocodyada tirtiridda waxaana lagu hayaa halkaas ilaa isbeddelka la rabo uu dhacayo.Nidaamku wuxuu u baahan yahay bir si ay hawadu u qaboojiso si loo abuuro hadhuudh la safeeyey.Tani waxay sidoo kale faa'iido u leedahay ka saarista miraha columnar iyo kala-soocidda dendritic, taas oo wax u dhimi karta tayada marka la tuurayo qayb.
Xanaaqa:Habkan waxaa loo isticmaalaa birta ku salaysan birta, gaar ahaan birta.Alloys-yadani aad bay u adag yihiin, laakiin inta badan aad bay u jajabaan ujeeddooyinkooda.Heerkulku wuxuu birta ku kululeeyaa heerkul wax yar ka hooseeya barta muhiimka ah, sababtoo ah tani waxay yaraynaysaa jajabnaanta iyada oo aan waxyeello u geysan qallafsanaanta.Haddii macaamiil uu rabo caag ka wanaagsan oo leh adayg iyo xoog yar, waxaanu ku kululaynnaa birta heerkul sare.Mararka qaarkood, in kastoo, alaabtu ay u adkaysanayso xanaajinta, waxaana laga yaabaa inay sahlanaato in la soo iibiyo walxo hore u engegay ama in la adkeeyo ka hor inta aan la farsamayn.
Adkeynta Kiis: Haddii aad u baahan tahay dusha adag laakiin udub dhexaadka ka jilicsan, adkaynta kiisku waa betka ugu fiican.Tani waa habka caadiga ah ee biraha leh kaarboon yar, sida birta iyo birta.Habkan, daaweynta kulaylku waxay ku daraysaa kaarboon dusha sare.Waxaad sida caadiga ah dalban doontaa adeeggan ka dib marka qaybo la farsameeyo si aad uga dhigto kuwo sii waaraya.Waxa lagu sameeyaa kulayl sare leh kiimikooyin kale, sababtoo ah taasi waxay yaraynaysaa khatarta ah inay ka dhigto qayb jajaban.
gabowga:Sidoo kale loo yaqaan adkeynta roobka, habkani wuxuu kordhiyaa awoodda wax-soo-saarka biraha jilicsan.Haddii birtu u baahan tahay qallafsanaan dheeraad ah oo ka baxsan qaab-dhismeedkeeda hadda, adkaynta roobabku waxay ku daraysaa wasakh si ay u kordhiso xoogga.Habkani wuxuu badanaa dhacaa ka dib marka la isticmaalo habab kale, oo kaliya waxay kor u qaaddaa heerkulka ilaa heerka dhexe waxayna si dhakhso ah u qaboojisaa walxaha.Haddii farsamayaqaanku go'aamiyo gabowga dabiiciga ah ugu fiican, alaabta waxaa lagu kaydiyaa heerkul qabow ilaa ay ka gaaraan sifooyinka la doonayo.
