Uyini umehluko phakathi kuka-201 insimbi engagqwali, 304 insimbi engagqwali, 316 insimbi engagqwali kanye titanium metal?

Insimbi engagqwali kanye ne-titanium yizinto ezisetshenziswa kakhulu emkhakheni wezimboni. Zinezinzuzo eziyingqayizivele mayelana nokusebenza, ukumelana nokugqwala kanye nezindleko. Phakathi kwabo, insimbi engagqwali ihlukaniswe yaba izinhlobo ezintathu: 201 insimbi engagqwali, 304 insimbi engagqwali kanye 316 insimbi engagqwali. Kukhona futhi umehluko phakathi kwabo.

Okokuqala, insimbi engagqwali engu-201 iwuhlobo lwensimbi engagqwali evamile equkethe i-manganese, esetshenziswa kakhulu ekuhlobiseni kwangaphakathi, ukukhiqizwa kwefenisha neminye imikhakha. Uma kuqhathaniswa nezinye izinhlobo ezimbili zensimbi engagqwali, insimbi engu-201 inamandla aphansi kodwa iyathengeka. Mayelana nokumelana nokugqwala, ukumelana nokugqwala kwensimbi engu-201 kungaphansi kwalokho kwe-304 ne-316 yensimbi.

Okwesibili, insimbi engagqwali engu-304 iyinsimbi engagqwali esetshenziswa kakhulu, eyakhiwe ikakhulukazi i-chromium engu-18% kanye ne-nickel engu-8%. Lolu hlobo lwensimbi engagqwali lunokumelana nokugqwala okuhle, ukumelana nezinga lokushisa eliphezulu kanye nokushisela, futhi intengo ilinganiselwe. Ngakho-ke, isetshenziswa kabanzi ekusetshenzisweni kokudla, imishini yezokwelapha, imishini yamakhemikhali neminye imikhakha.

Ngaphezu kwalokho, insimbi engagqwali engu-316 ifana nensimbi engagqwali engu-304, kodwa iqukethe i-2% -3% molybdenum, enokumelana nokugqwala okungcono. Insimbi engagqwali engu-316 isetshenziswa kabanzi ezindaweni zasolwandle nasezindaweni ezine-acidic, futhi isetshenziswa kabanzi ekwenzeni izinto zamakhemikhali, izinto zasolwandle kanye neminye imikhakha.

Okokugcina, insimbi ye-titanium iyimpahla engasindi, enamandla aphezulu enokumelana nokugqwala okuhle kakhulu, ukumelana ne-oxidation kanye ne-biocompatibility. Ngakho-ke, isetshenziswe kabanzi ku-aerospace, imishini yezokwelapha, imishini yezemidlalo kanye neminye imikhakha. Kodwa-ke, intengo yensimbi ye-titanium iphakeme kakhulu, okungenye yezizathu zokuthi kungani ukusetshenziswa kwayo kunomkhawulo.

Ngokuvamile, 201 insimbi engagqwali, 304 insimbi engagqwali,316 insimbi engagqwalikanye nensimbi ye-titanium ngayinye inezinzuzo zayo kanye nokubi emikhakheni ehlukene. Ukukhethwa kwezinto kudinga ukucatshangelwa kwezinto eziningi, njengemvelo, izimo zomthwalo, izindleko, njll.
