I-Carbide yethusi ekhishwe

I-1) Ukuqina okuhle kakhulu nokumelana nokugqoka Emazingeni okushisa asekamelweni, ubulukhuni bei-carbide enosimendeingafinyelela ku-8693HRA, okulingana no-6981HRC.Inobunzima obuphezulu be-900-1000 ° C kanye nokumelana nokugqokwa okuhle.Ijubane lokusika lingaba izikhathi ezingu-4-7 ngokushesha kunensimbi yamathuluzi esivinini esikhulu, impilo yesevisi inganwetshwa izikhathi ezingu-5-80, futhi ingasika izinto eziqinile ngobulukhuni kuze kufike ku-50HRC.2) Amandla aphezulu, ukunwebeka okuphezulu Amandla acindezelayo e-carbide enosimende afinyelela ku-6000MPa, futhi i-modulus of elasticity yi-(4-7)×105MPa, enkulu kunaleyo yensimbi enesivinini esikhulu.Kodwa-ke, amandla ayo okuguquguquka aphakathi, kusukela ku-1000 kuya ku-3000 MPa.I-3) Ukumelana nokugqwala okuhle kakhulu kanye nokumelana ne-oxidation Imelana nomoya, i-asidi, i-alkali nokunye ukugqwala, akulula ukwenza i-oxidize.4) I-coefficient ephansi yokunwetshwa komugqa Ngesikhathi sokusebenza, umumo nosayizi kuhlala kuzinzile.5) Akukho okunye ukucubungula noma ukugaywa kabusha kwezinto ezibunjiwe.Ngenxa yobulukhuni obukhulu kakhulu kanye nokuqina kwe-brittlenessi-carbide enosimende, ayikwazi ukusikwa noma igaywe kabusha ngemuva kokwakhiwa kwe-powder metallurgy kanye nokucwiliswa.Lapho ukusetshenzwa kabusha kudingekile ngempela, kungasetshenziswa kuphela umshini wokukhipha ugesi, ukusika izintambo, ukugaya i-electrolytic, njll. noma ukugaya okukhethekile kwesondo lokugaya kungasetshenziswa.Ubukhulu, ngokuvamile benziwa nge-carbide enosimende, buqiniswa, bunamathiselwe, noma buboshwe ngomshini emzimbeni wamathuluzi noma ziyafa.
