Bare e Phahameng ea Aluminium ea C95400 ea Boronse e Chitja - Sesebelisoa sa ho Lahlela

Bara ea Boronse ea Ni-Al (C95800 / CuAl10Fe5Ni5-C) – Tlhaloso ea Sehlahisoa sa Tekheniki

Thepa ena e hlahisoa ka ho lahla ho sa khaotseng kapa ho sa khaotseng ho lateloa ke mekhoa ea ho ntša metsi a chesang a nang le li-pass tse ngata le ho hula/ho qeta ho batang ho netefatsa sebopeho se teteaneng sa microstructure, se se nang masoba le lintho tse sa keneng tšepeng, ka boholo ba lijo-thollo tse tšoanang. Sebopeho sa lik'hemik'hale se laoloa ka thata ka hare ho ± 0.15% bakeng sa likarolo tsa bohlokoa (Ni, Al, Fe) ka ho latela ka botlalo ASTM B148, EN 1982, kapa GB/T 12225, ka litšila tsohle tse ka tlase ho 0.10%.

Taolo ea boleng ba ts'ebetso e felletseng ea kenngoa tšebetsong

● Ho qhibiliha ho etsoang ka har'a ontong ea induction ea maqhubu a mahareng ka sekoahelo sa flux le argon shielding; tekanyo ea oksijene <10 ppm;
● Teko ea 100% ea li-billet tse entsoeng ka ultrasound (ho latela ASTM B584 Sehlopha sa 1);
● Tharollo e tharo e annealing + kalafo ea mocheso oa botsofali kamora ho ntša metsi ho ntlafatsa kabo ea α le κ ea mohato, ho fihlela boima bo tsitsitseng HB180-240;
● Sehlopha se seng le se seng se ile sa tshwarwa ke ho kgopama, ho thulana, ho kgopama ha di-granular (ASTM G110), ho kgopama ha kgatello (ASTM G36/G44), ka tlhahlobo ya motho wa boraro (SGS/Pony) le setifikeiti sa 3.1 ho ya ka EN 10204.

Thepa e tloaelehileng (φ30-200 mm)

● Matla a ho thapolla ≥ 690 MPa
● Matla a tlhahiso ≥ 330 MPa
● Ho lelefatsa ≥ 12%
● Sekhahla sa ho bola ha metsi a leoatle ≤ 0.02 mm/selemo (se lekanang le lilemo tse 40)

E loketse li-propeller tsa leoatle tse boima, li-valve stems, li-shaft tsa pompo tse matla haholo tse hanelang mafome, le likarolo tsa bohlokoa tsa sebopeho tse pepesehetseng metsi a leoatle lits'ebetsong tsa likepe le tsa leoatle.

Re ikhethile ka ho fana ka boronse ea nickel-aluminium ea boleng bo holimo, e ka lateloang ka botlalo ho likhoebo tse kholo tsa kaho ea likepe, indasteri e boima, liforomo tsa leoatleng le mafapheng a peterole. Boholo ba lotho ke lithane tse 50-300, ka bokhoni ba litumellano tsa nako e telele tse netefatsang sebopeho se tsitsitseng le thepa ea mechini.
