Màndarga yi ak jëfandikoo cër yu dóomu taal bu dóomu taal.
I. màndarga
1. màndarga mekanik
Doole bu ndaw: effet cleavage matrix bi graphite flake bi waral leer na, te dooley noyyig bi dafa gëna suufe bu baax ak asiye, waaye dooley kompressif mën na yegg 3-4 yoon ci dooley noyyig bi.
Resistance bu baax: matrix matrix pearlitique fer (lu melni HT200-HT250) dafa am dëgëraay bu rëy ak wear ndax séddale bu baax ci graphite.
2. Màndarga yi ci liggéey
Absorption choc bu am solo: fiche graphite mën na xëcc energie vibration, kàttanu absorption choc bi mingi tollu ci 10 yoon li asiye, bu méngoo ak jumtukaayi masin, kadre ak ñoom seen.
Li gëna am solo ci wàllu casting mooy: composition carbone mingi jege composition eutetik, fluidité bu baax, shrinkage bu woyof, méngoo ak sànni miir yu woyof wala cër yu jafee xam (lu melni tige, boyet).
Lubrication graphite bu baax: lubrifiant graphite dafay wàññi solar jumtukaay ak dagg chip bu yomb.
3. Differenci mbootaay
Xeetu matrix bu mëna jeex: xaaj ko ci ferrite (HT100), ferrite-pearlite (HT150), pearlite (HT200-HT250) ak wen wu judd (HT300-HT350) buñu sukkandikoo ci structure matrix, ngir mëna am doole ci doole.
morfoloji graphite bi dafa taxaw: structure graphite flake bi dafa dëgër, waaye catu bi dafa bari luñu koy teg ci stress, te loolu dafay tënk plastisite ak dëgëraay bi.
II. Amna tool
1. Defarkati mekanik
Koposaŋ bu baax ci jumtukaayu masin: Pearlite dóomud wen (HT200) dañu koy jëfandikoo ngir lal, rail bu njiit, liggéey ak yeneen senaario yu am doole yuy xeex doole.
Kadre ak dëkkuwaay: Ferrite- fer bu dóomu taal bu am dóomu taal (HT150) mën na nekk ci masin, bracket, yaram valve, yaram valve, ak yeneen cër yu yam.
2. automobile ak dem ak dikk
Sistemu kuuraŋ: Block silindre motër, liner silindre ak ñoom seen, ñu defaree ko ci wen pearlitik, muy tàngoor wu metti te am gaz bu bari.
Piyeesu frein yi: silindër frein locomotif, piston ak yeneen mbir yu ñuy sol- cër yiy faral di jëfandikoo wen wuñ dagg (HT300).
3. Architekte ak affiiru munisipaal yi
Piyeesu saafara: wen wu gëna am doole (HT100) dañu koy jëfandikoo ngir muur mannhole, tuyo drainage ak yeneen senaario yu néew.
Access yi: ñag fer, radiatëru radiatëru liggéey ak rafet.
4. Liggéeyukaay yu am doole ak yu diis
Gaalu pressure: njariñu dooley kompresioŋ moo tax mu baax ci yaramu silindre hydraulique, vanne pression bu kawe.
Jumtukaayi metallurgique: matrix bu mag bu am gray bu am gray bu dëgër, dafay baña tàng tàngoor wu metti, ñu koy jëfandikoo ci jumtukaayi chaudier yi, moule metallurgique yi.
