U habaynta fasalada kala duwan
Darajada D, E (DH32, DH36, EH 32, EH 36)
Taxanaha darajada D iyo E (ay ku jiraan AH32/36, DH32, DH36, EH32, EH36) taarikada birta dhiseysa waxay u baahan yihiin adkeysi heerkul hoose oo wanaagsan iyo waxqabadka alxanka wanaagsan. Soo saarista saxan bir ah oo dhiseysa maraakiibta xoogga badan waxay u baahan tahay in la caadiyeeyo iyada oo la adeegsanayo wareegyada la xakameeyey iyo qaboojinta xakamaynta ama hababka daaweynta kulaylka oo leh qalab dhamaystiran. Isla mar ahaantaana, nadiifinta birta gudaha ee birta la keenay ayaa looga baahan yahay inay sare u kacdo, gaar ahaan waxa ku jira S, P, N, 0 iyo H ee birta waa in si adag loo xakameeyo.
Walxaha Alloy lagu daray si loo hagaajiyo adkaanta
Si loo hubiyo waxqabadka taarikada markabka ee xoogga badan, tignoolajiyada yar-yar ayaa la qaataa. Markaad ku darto Nb, V, Ti iyo walxo kale oo daawaynta birta ah, oo ay weheliso habka duubista la xakameeyey, hadhuudhka waa la sifeeyaa oo adkaanta waa la hagaajiyaa.
Jihada Horumarka ee Saxanka Dhisida Maraakiibta
Awood sare, qeexid sare, oo leh baaxad weyn oo markabka iyo badbaadada, iyo isbeddelka qeexida dahaarka, baahida loo qabo dabaqyada caadiga ah ee A-class ayaa si tartiib tartiib ah loo dhimay, iyo baahida loo qabo muraayadaha xoogga badan ayaa sii kordhaya, kuwaas oo ku urursan maraakiibta waaweyn. oo ballac ah 5m. Saxan, 200-300mm oo dhumucdiisuna waxay tahay looxa markabka qaro weyn.
