Astaamaha Daawaynta Kulaylka ee Dabaysha Daabka Daawaha Dhexdhexaadka ah iyo Kuwa Hoose:
1. Shubka birta dhexdhexaadka ah iyo kuwa hooseeya waxaa inta badan loo adeegsadaa warshadaha mishiinada sida baabuurta, cagafyada, tareenada, mishiinada dhismaha, iyo nidaamyada hawo-biyoodka. Warshadahani waxay u baahan yihiin wax tuurista oo leh xoog iyo adkeysi wanaagsan. Tuubbooyinka u baahan xoog xajin oo ka yar 650 MPa, caadi ahaan + daawaynta kulaylka heerkulka ayaa guud ahaan loo isticmaalaa; loogu talagalay shubista birta daawaha dhexdhexaadka ah iyo kuwa hooseeya kuwaas oo u baahan xoog xajin oo ka weyn 650 MPa, quenching + heerkulka sare ee kuleylka kuleylka ayaa la isticmaalaa. Daminta iyo xanaaqa ka dib, qaab dhismeedka birta ah ee wax lagu shubo birta ayaa lagu xanaaqaa sorbite, si loo helo xoog sare iyo qallafsanaan wanaagsan. Si kastaba ha ahaatee, marka qaabka iyo cabbirka wax-shubashadu aanay ku habboonayn deminta, caadi-yeelaynta + xanaaqa waa in la adeegsadaa halkii la damin lahaa oo la dabci lahaa.
2. Way fiicantahay in la sameeyo caadiyaynta ama caadi ka dhigista Sidan oo kale, hadhuudhka crystal ee shubista birta waa la sifayn karaa oo qaab dhismeedka lebbiska, si kor loogu qaado saamaynta ugu dambeeya ee deminta iyo daawaynta, iyo sidoo kale ka caawinta in laga fogaado saamaynta xun ee culayska shubida gudaha shubida.
3. Ka dib daawaynta deminta, dhexdhexaadinta birta birta ah ee dhexdhexaadka ah iyo kuwa hooseeya waa inay helaan qaabka martensite sida ugu macquulsan. Si loo gaaro yoolkan, heerkulka deminta iyo dhexdhexaadinta qaboojinta waa in lagu doortaa iyadoo loo eegayo darajada birta la shubay, adkaanta, dhumucda derbiga tuurista, qaabka iyo arrimo kale.
4. Si loo hagaajiyo qaab dhismeedka deminta birta kabka, loogana takhaluso diiqada deminta, dhex dhexaadka iyo birta daawaynta hoose waa in isla markiiba la damiyaa ka dib.
5. Marka la eego dhismaha aan la dhimin xoogga birta wax lagu shubo, kaarboon dhexdhexaad ah oo dhexdhexaad ah oo kaarboon ah oo hooseeya ee xoogga sare leh ayaa la adkeyn karaa. Daawaynta adag waxay wanaajin kartaa caagagga iyo adkaanta shubista birta.
