● Mekhaniki: Matla a ho tsikinyeha ≥1200 MPa, matla a tlhahiso ≥900 MPa, phokotso ea sebaka ≥40%
● Ditshebediso: Di sebediswa dithapong tsa tshepe tsa terata, di-spring tsa ho fanyeha tsa dikoloi, le tlhahisong ya thapo ya thaere ya radial.
Lithupa tsa terata tsa tšepe tse nang le hlooho e batang tsa SAE1008:
● Taolo ea Lielemente: C 0.06–0.10%, Mn 0.30–0.50%, P/S ≤0.030%
● Litekanyo tsa Ductility: Ho lelefatsa ≥30%, phokotso ea sebaka ≥65%
● Likarolo tsa Ts'ebetso: Hlooho e batang e nepahetseng haholo bakeng sa ho etsa liboutu tse matla haholo, li-bearing, le likarolo tsa hardware, e sebeletsang liketane tsa phepelo ea likoloi le lisebelisoa tsa lapeng.
Lithupa tse Ikhethang tsa Motsoako oa Tšepe bakeng sa Maemo a Feteletseng
Likhoele tsa terata tsa motsoako oa CrMo tse 30:
● Sebopeho sa Alloy: C 0.26–0.34%, Cr 0.80–1.10%, Mo 0.15–0.25%
● Tshebetso ea Mocheso o Phahameng: Matla a tlhahiso ≥550 MPa ho 550°C, matla a ho tsikinyeha ≥930 MPa mochesong oa kamore
● Ditshebediso: Ho kgopama ha mafome le mocheso bakeng sa dithapo tsa ho tjheka oli, diboutu tsa ankora ya tora ya turbine ya moya, le dihokelo tsa sefofane.
Likhoele tsa terata tse betliloeng tsa BZn18-18:
● Boitsebiso ba Motheo: C ≤0.08%, Cu 0.25–0.40%, Zn 18–20%
● Liparamente tsa ho roala: Galfan® alloy coating (Zn-5%Al-RE), boima ba ho khomarela 200–300 g/m²
● Ho tsamaisa motlakase: Ho sebelisoa ka har'a likhoele tsa gridi ea motlakase le terata e sireletsang bakeng sa tikoloho ea kantle.
Melemo ea Ts'ebetso le Litataiso tsa Khetho ea Lintho
Mahlale a tsoetseng pele a ho phutholla le ho pholisa a laoloang ka lebelo le phahameng a netefatsa ho nepahala ha boholo (± 0.1 mm) le ho tšoana ha sebopeho sa microstructural, a tšehetsang lits'ebetso tse latelang joalo ka ho hula le kalafo ea mocheso. Khetho ea thepa e tlameha ho latela maemo a indasteri (ASTM, GB/T, JIS), e behe pele litaba tsa khabone, bolelele le taolo ea sekoli sa bokaholimo.
Jwalo ka mofani wa lefatshe ka bophara wa thupa ya terata, re fana ka ditharollo tse felletseng bakeng sa dithapo tsa tshepe, dikarolo tse batang tse tloaelehileng, le thepa e ikgethang ya terata ya alloy, re matlafatsa bareki ho fokotsa ditjeo le ho ntlafatsa bokgoni. Ikopanye le rona hona jwale bakeng sa dikhataloganyo tsa dihlahiswa tse ikgethileng le tshehetso ya botekgeniki!
