Iyada oo loo marayo habab kala duwan oo hab-nololeedka qabow iyo dib-u-habaynta dusha sare ka dib rogid, dhammaadka dusha sare ee gariiradaha birta ah waxay yeelan karaan noocyo kala duwan.
Birta aan birta lahayn waa walxo la isku bedeli karo oo waara oo loo isticmaalo codsiyo kala duwan oo kala duwan, laga bilaabo maacuunta jikada ilaa qalabka dhismaha. Gariiradaha birta ah ee birta ah ayaa ah qayb muhiim ah oo ka mid ah alaabooyin badan maadaama ay bixiyaan hab lagu sameeyo walxaha qaabab iyo cabbiro gaar ah. Aynu si qoto dheer u eegno habka wax soo saarka ee gariiradaha birta ah.
1. Dhallaanka iyo sifaynta: Tallaabada ugu horreysa ee habka wax-soo-saarku waa in la dhalaaliyo alaabta ceeriin ee loo isticmaalo samaynta birta aan-soo-saarka lahayn-sida caadiga ah birta, nikkel, chromium, iyo biraha kale. Tan waxaa lagu sameeyaa foornada ama foornada, inta badan waxaa la isticmaalaa faashad koronto ah ama foorno wax-qabad ah. Birta dhalaalaysa ee ka dhalata ayaa markaa la sifeeyaa si meesha looga saaro wasakhda oo loo hubiyo in ay ku habboon tahay daawaha.
2. Kaxaynta: Ka dib marka birta la sifeeyo, waxa lagu shubaa caaryaal si ay u samaysmaan biraha shubka ah. Jaranjarada waxay noqon kartaa dhumuc dhowr inji ah oo miisaankeedu yahay 20 tan ama ka badan. Habka shubista waxaa inta badan lagu sameeyaa mashiinka shubista joogtada ah, kaas oo dammaanad qaadaya socodka joogtada ah ee walxaha iyo waxtarka weyn.
3. Duubista kulul: Dabaqadu waa la kululeeyaa oo la dhex maraa silsilado duub oo kulul. Warshadaha duuban waxaa lagu qalabeeyaa duubo isku cadaadiya oo u qaabeeya birta go'yaal dhuuban ama strips. Habka duubista kulul waxay dhalin kartaa heerkul ka badan 1,000 darajo Celsius, taas oo u oggolaanaysa walxaha in la qaabeeyo iyada oo aan jabin.
4. Duubista qabow: Ka dib marka la dhammeeyo habka rogrogmada kulul, birta aan nadiifka ahayn ayaa markaa qabow lagu duubaa si loo gaaro dhumucda la rabo iyo dhammaadka dusha sare. Tani waxay ku lug leedahay gudbinta walxaha iyada oo loo marayo taxane qaboojiye ah oo duuban, kuwaas oo sii cadaadiya oo qaabeeya birta. Duubista qabowgu waxa kale oo ay kordhisaa xoogga iyo cimri dhererka birta-la'aanta ah, taas oo ka dhigaysa mid adkeysi badan oo waara.
5. Annealing: Marka birta aan-daawaynta ahi qabowdahay oo la rogo dhumucda la rabo, waa la tirtiraa inta lagu jiro daaweynta kulaylka. Tani waxay ku lug leedahay kuleylinta walxaha heerkul sare ka dibna si tartiib ah u qaboojiso waqti ka dib. Annealing waxa ay ka caawisaa in ay jilciso birta aan fiicnayn waxana ay kordhisaa ductility, taas oo sahlaysa samaynta gariiradda ama qaabab kale.
6. Jeexdin iyo duubid: Ugu dambayntii, birta aan la kala saarin waxay u qaybsantaa xariijimo-la googooyay qaybo dhuuban-kadibna lagu duubo si loo raro loona kaydiyo. Habkan waxaa badanaa lagu sameeyaa iyadoo la isticmaalayo qalab gaar ah sida jeexjeexyada iyo garooriyaha. Gariiradda ayaa markaa loo rari karaa wax-soo-saare ama wax-soo-saare kaasoo agabka u isticmaali doona inuu abuuro badeeco dhammaatay.
