Kuita kwemaforging kwakakosha mune akasiyana maindasitiri ekushandisa, kubva kuzvinhu zvemotokari kuenda kune aerospace zvikamu. Kuwedzerwa kwezvinhu zvakasiyana-siyana zvealloy zvinogona kukanganisa zvakanyanya zvimiro zvezvakagadzirwa, kuwedzera simba razvo, kusimba, uye kuramba kune zvakatipoteredza zvinhu. Ichi chinyorwa chinoongorora zvimwe zveakakosha alloying zvinhu uye mabatiro avanoita kuita kwemafogi.
Key Alloying Elements uye Migumisiro Yazvo
Kabhoni (C):
Carbon ndechimwe chezvinhu zvinonyanya kukosha alloying musimbi. Iyo inokanganisa zvakananga kuoma uye kusimba kwezvinhu. Yakakwira kabhoni yemukati inowedzera kuoma uye kusimba kwesimba rekugadzira, ichiita kuti ive yakakodzera kune maapplication anoda yakakwira kupfeka kuramba, senge maturusi ekucheka uye zvikamu zvemotokari. Nekudaro, kabhoni yakawandisa inogona kuita kuti zvinhu zvipere, zvichideredza kupikisa kwayo.
Chromium (Cr):
Chromium inozivikanwa nekugona kwayo kuvandudza corrosion resistance uye kuoma. Iyo inoumba passive layer yechromium oxide pamusoro, ichidzivirira kuumbwa kubva kune oxidation uye ngura. Izvi zvinoita kuti simbi dzechromium-alloyed dzive dzakanakira kunyorera munzvimbo dzakaomarara, senge maindasitiri emugungwa nemakemikari. Pamusoro pezvo, chromium inosimudzira kuomarara kwesimbi, ichibvumira kuti iwane simba repamusoro uye kuoma mushure mekurapwa kwekupisa.
Nickel (Ni):
Nickel inowedzerwa kune forgings kuvandudza kusimba kwavo uye ductility, kunyanya pakudziya kwakadzika. Iyo zvakare inokwidziridza kuramba kweiyo zvinhu kune ngura uye oxidation. Nickel-alloyed steels anowanzo shandiswa muaerospace uye oiri & gasi maindasitiri, uko zvese zvakakwirira simba uye kuramba kune dzakaoma nharaunda zvinodiwa. Kuvapo kwenickel zvakare kunodzikamisa iyo austenitic chikamu, ichiita iyo simbi isiri-magnetic uye inovandudza kushanda kwayo.
Yakasanganiswa Mhedzisiro uye Maindasitiri Zvikumbiro
Iko kusanganiswa kweizvi uye zvimwe zvinhu zvealloying, senge molybdenum (Mo), vanadium (V), uye manganese (Mn), inogona kugadzira zvinhu zvine zvivakwa zvakagadzirirwa zvekushandisa chaiko. Semuenzaniso, molybdenum inowedzera kusimba kwepamusoro-tembiricha uye inokambaira kuramba kwesimbi, ichiita kuti ive yakakodzera kune turbine blades uye kumanikidza midziyo. Vanadium inonatsa chimiro chezviyo, ichivandudza kusimba uye kuoma kwekugadzira. Manganese inoshanda se deoxidizer uye inovandudza kuoma uye kusimba kwesimba rezvinhu.
Muindasitiri yemotokari, mafogi ane musanganiswa wakaenzana wekabhoni, chromium, uye manganese anoshandiswa kugadzira yakakwirira-simba, inodzivirira kupfeka zvinhu senge crankshafts uye magiya. Muchikamu chemuchadenga, nickel uye titanium alloys akakosha pakugadzira zvikamu zvisingaremi asi zvakasimba zvinokwanisa kushingirira tembiricha yakanyanyisa uye kushushikana.
Mhedziso
Kuita kwemafogi kunokanganiswa zvakanyanya nekuwedzera kwealloying zvinhu, imwe neimwe ichipa chaiwo zvivakwa zvinosimudzira kuita kwese kwechinhu. Kunzwisisa basa rezvinhu zvakaita sekabhoni, chromium, uye nickel kunobatsira ma metallurgists nemainjiniya kugadzira mafogi anozadzisa zvinodiwa zveakasiyana maindasitiri ekushandisa. Nekunyatsosarudza uye nekusanganisa zvinhu izvi, vagadziri vanogona kugadzira emhando yepamusoro mafogi ane simba repamusoro, kusimba, uye kuramba kune zvakatipoteredza zvinhu, kuve nechokwadi chekuvimbika uye hupenyu hurefu mumashandisirwo avo.
