Powder Metallurgy Stainless Simbi
Nzira yekutanga yekugadzira poda metallurgy yesimbi isina tsvina ndeye:
Kugadziriswa kwesimbi isina tsvina poda metallurgy inonyanya kushandisa hupfu uhu sehupfu, hunozocheneswa nekunatswa uchishandisa nzira yekuumba. Kusanganisa hupfu, kudzvanya, kunyudza, kupedzisa, uye kugadziridza-matanho ekutanga muhupfu hwesimbi inogadzirwa nesimbi isina tsvina. Zvimwe zviitiko zvakawanda zvinowira pasi pechikamu chemashure-kugadzirisa, kusanganisira machining, kurongedza, uye kupinza mafuta.
Mukuita uku kuyerera, iyo yakagadzirwa simbi isina tsvina poda inotanga kusanganiswa kugadzira yakakwirira-kuchena yakasanganiswa poda. Hupfu hunotakurwa muforoma uye hwotsikirirwa kuita chimiro pasi pekumanikidzwa kwakati. Iyo yakadzvanywa shizha regirini rinozoiswa munzvimbo inodzorwa sintering furnace uye yakanyungudutswa pane tembiricha iri pazasi pekunyungudika kwezvinhu zvematrix, zvichiita kuti zvidimbu zvehupfu zviitike kurapwa kwepamusoro-tembiricha uye kuumba metallurgical bond.
Ngatitangei kusuma maitiro eStainless simbi poda metallurgy processing mumatanho.
- Kusanganisa
Sanganisa hupfu hwesimbi isina tsvina nezvinowedzerwa uye uzvikurungadze maererano nenguva inodiwa kuti uite hupfu hwepamusoro hwakasanganiswa.
- Kuumba
Zvinoenderana nehukuru, chimiro, chimiro uye dhizaini mold dhizaini yechigadzirwa, dzvanya kuti igadzire carbide mold, wozoisa muchina wekuyedza mold, uye kuyedza sample. Iyo mold dhizaini uye kutenderera kwekugadzira ivhiki imwe.
- Degreasing
Iyo tembiricha yekudzikisa inodzorwa pa800 madhigirii, uye vacuum bhero choto kana mesh bhandi choto rinoshandiswa kudzikisa. Chinangwa ndechokubvisa mafuta akawedzerwa.
- Sintering
Mukugadzirisa kwesimbi isina tsvina poda metallurgy, sintering ndiyo nzira yakakosha. Iwo ekupedzisira emuviri uye emagetsi zvimiro anodiwa neakaumbwa compact anowanikwa ne sintering. Sintering yakakamurwa kuita unit system sintering uye yakawanda-chikamu system sintering. Mukugadzirwa chaiko, kune yakasimba chikamu sintering yeyuniti system uye yakawanda-chikamu system, sintering tembiricha yakadzikira pane inonyungudika yesimbi uye alloy inoshandiswa.
- Kurapa kwakatevera
Kurapa kunotevera mushure mekupisa kunogona kupedzwa nenzira dzakasiyana maererano nezvinodiwa zvakasiyana zvechigadzirwa. Semuenzaniso, kupedzisa, kuisa mafuta, machining, kupisa kupisa uye electroplating zvinowanzoshandiswa mukugadzirwa chaiko. Mukuwedzera, mumakore achangopfuura, mamwe maitiro matsva akagadzirwa, akadai sekukungurusa nekuforoma. Aya maitiro anogona zvakare kuiswa pakugadziriswa kwehupfu metallurgy zvinhu mushure mekunyungudika kuti uwane mamwe akanakisa kugadzirisa maitiro.
Nzira dzekuvandudza kusimba uye kuoma kwehupfu metallurgy Stainless simbi
Kutanga, simbi isina tsvina poda inoumbwa kuita muviri, uye ipapo mutumbi unoiswa munzvimbo inoderedza uye inochengetwa painodziya tembiricha kuti iite sintered muviri. Zvadaro, iyo sintered muviri inoratidzirwa kune kabhoni-ine mhepo uye inochengeterwa pane carburizing tembiricha iri pasi pe600 ° C, kuitira kuti kabhoni igadzire nzvimbo ine carburized pamusoro uye mukati meiyo sintered muviri. Nenzira iyi, kuoma uye kusimba kwehupfu metallurgy simbi isina tsvina inogona kuvandudzwa kuburikidza nenzvimbo yakasvibiswa, uye nokuti kupisa kwekushisa kuri pasi pe600 ° C, maitiro pakati pekromium nekabhoni anogona kudziviswa, kuitira kuti kumira kwakanaka kwekuora kunogona kuchengetedzwa.
Key Stainless Simbi Magiredhi muPowder Metallurgy
