(1) Ukuqina okuphezulu, ukumelana nokugqoka kanye nobulukhuni obubomvu
Ukuqina kwe-carbide okusikiwe ekamelweni lokushisa kungafinyelela ku-86 ~ 93HRA, okulingana no-69 ~ 81HRC.ngo-900 ~ 1000 ℃ ingagcina ubulukhuni obuphezulu, nokumelana nokugqoka okuhle kakhulu.Uma kuqhathaniswa nensimbi yamathuluzi esivinini esikhulu, ijubane lokusika lingaba izikhathi ezi-4 kuye kweziyi-7 ngaphezulu, ukuphila izikhathi ezi-5 kuye kwezingama-80 ubude, lingasika izinto eziqinile ngobulukhuni kuze kufike ku-50HRC.
(2) Amandla, i-modulus ephezulu yokunwebeka
Amandla acindezelayo e-carbide enosimende afika ku-6000MPa, i-elastic modulus (4 ~ 7) × 105MPa, aphakeme kunensimbi enesivinini esikhulu.Kodwa-ke, amandla ayo okuguquguquka aphansi, ngokuvamile i-1000 kuya ku-3000 MPa.
(3) Ukumelana nokugqwala, ukumelana ne-oxidation kuhle
Ngokuvamile ukumelana okuhle nokugqwala komkhathi, i-asidi, i-alkali, njll., akulula ukwenza i-oxidation.
(4) I-coefficient encane yokunwetshwa komugqa
Isimo nosayizi ozinzile lapho usebenza.
(5) Imikhiqizo eyenziwe ayisacutshungulwa futhi ilolwe kabusha
Ngenxa yokuqina okuphezulu nokuqina kwe-carbide enosimende, akusekho ukusika noma ukugaywa ngemuva kokwakhiwa kwe-powder metallurgy kanye nokucwiliswa, futhi uma kudingekile ukusetshenzwa kabusha, kungasetshenziswa kuphela imishini kagesi efana ne-EDM, ukusika izintambo, ukugaya i-electrolytic noma isondo elikhethekile lokugaya. .Imvamisa ukucaciswa okuthile kwemikhiqizo eyenziwe nge-carbide enosimende iba brazed, iboshwe noma iboshwe ngomshini emzimbeni wamathuluzi noma isikhunta esiqondiswe ukusetshenziswa.
