Kutanga, taura nesu nekukurumidza. Chido chedu ndechekugadzira simbi yehupfu, uye isu tinogona kubatsira!
POWDER METAL MATERIALS
Iron-based powder metallurgy zvinhu
Iron-based powder metallurgy zvinhu zvinonyanya kuumbwa nesimbi, uye kirasi yesimbi nesimbi zvinhu zvinogadzirwa nekuwedzera alloying zvinhu zvakaita seC, Cu, Ni, Mo, Cr, uye Mn. Iron-based products ndiyo inonyanya kugadzirwa mhando yezvinhu muindasitiri yehupfu simbi.
1. Iron-based powder
Iwo mapoda anoshandiswa muupfu simbi-yakavakirwa zvinhu uye zvigadzirwa zvinonyanya zvinosanganisira yakachena simbi poda, iron-based composite poda, iron-based pre-alloyed poda, nezvimwe.
2. PM iron-based products
Tekinoroji yekutsikirira / sintering tekinoroji inogona kazhinji kugadzira zvigadzirwa zvesimbi zvine density ye6.4 ~ 7.2g/cm3, iyo inoshandiswa mumotokari, midhudhudhu, midziyo yemumba, maturusi emagetsi uye mamwe maindasitiri, nezvakanakira kunyura, kuderedza ruzha, uremu huremu uye kuchengetedza simba.
3. Powder injection molding (MIM) iron-based products
Metal poda jekiseni molding (MIM) inoshandisa simbi hupfu seyakabikwa kugadzira zvidimbu zvidiki zvesimbi zvine maumbirwo akaomarara nenzira yepurasitiki jekiseni rekuumba. Panyaya yeMIM zvinhu, 70% yezvinhu zvinoshandiswa pari zvino isimbi isina tsvina uye 20% isimbi yakaderera-alloy. Tekinoroji yeMIM inoshandiswa zvakanyanya munharembozha, komputa uye maindasitiri emidziyo yekubatsira, senge nharembozha SIM zvimedu, mhete dzekamera, nezvimwe.
Powder metallurgy cemented carbide
Cemented carbide ihupfu simbi yakaoma zvinhu ine shanduko yeboka refractory simbi carbide kana carbonitride sechinhu chikuru. Nekuda kwesimba rayo rakanaka, kuomarara uye kuomarara kunoenderana, simende carbide inonyanya kushandiswa sematurusi ekucheka, maturusi emigodhi, maturusi asingapfeki, sando dzepamusoro, mipumburu, nezvimwewo, uye inoshandiswa zvakanyanya musimbi, mota, aerospace, CNC muchina maturusi. , indasitiri yemichina Mould, marine engineering midziyo, njanji yekufambisa, indasitiri yeruzivo rwemagetsi tekinoroji, muchina wekuvaka uye zvimwe midziyo yekugadzira nekugadzirisa uye migodhi, mafuta uye gasi sosi. kuchera, kuvaka zvivakwa uye mamwe maindasitiri.
Upfu metallurgy magineti zvinhu
Magnetic zvinhu zvakagadzirirwa nehupfu hwekuumba uye sintering nzira dzinogona kukamurwa kuita mapoka maviri: poda metallurgy inogara magineti zvinhu uye yakapfava magineti zvinhu. Zvisingaperi zvemagineti zvinhu zvinonyanya zvinosanganisira samarium cobalt isingawanzo pasi magineti zvinhu, neodymium, simbi, boron zvachose magineti zvinhu, sintered AlNiCo zvechigarire magineti zvinhu, ferrite zvechigarire magineti zvinhu, nezvimwe.
Mukana wepoda simbi yekugadzira magineti zvinhu ndezvekuti inokwanisa kugadzirira magineti muhukuru hwenzvimbo imwe chete, kuwana inopindirana yehupfu hwemagineti panguva yekutsikirira, uye yakananga kuburitsa yakakwirira magineti emagetsi chigadzirwa magineti padyo nechimiro chekupedzisira, kunyanya. kune yakaoma-ku-muchina yakaoma uye brittle magineti zvinhu. Panyaya yezvigadzirwa, zvakanakira zvehupfu metallurgy zvinonyanya kuoneka.
Powder metallurgy superalloys
Powder metallurgy superalloys yakavakirwa pa nickel uye inowedzerwa nezvinhu zvakasiyana-siyana zvealloying zvakaita seCo, Cr, W, Mo, Al, Ti, Nb, Ta, etc. Iyo ine yakanakisa tembiricha yekusimba, kusaneta uye kupisa kupisa kwegora uye zvimwe zvakazara. properties. Iyo alloy ndeyezvinhu zvakakosha zvekupisa-magumo zvikamu zvakadai seaero-injini turbine shafts, turbine disk baffles, uye turbine disks. Kugadziriswa kunonyanya kusanganisira kugadzirira hupfu, kupisa kwekubatanidza kuumba, uye kurapwa kwekupisa.
Chikwata chedu chehunyanzvi chinozopa zano pamusoro pezvishandiso zvinoenderana nemidziyo yakoupfu simbi zvikamu. Huwandu hwakakura hwezvigadzirwa zvinogona kushandiswa kugutsa zvaunoda maererano nemutengo, kusimba, kutonga kwemhando, uye mashandisirwo chaiwo ndeimwe yemabhenefiti makuru ekushandisa poda simbi kugadzira zvikamu. Simbi, simbi, tin, nickel, mhangura, aruminiyamu, uye titanium ndedzimwe simbi dzinowanzo shandiswa. Zvinokwanisika kushandisa simbi dzinoramba dzinosanganisira bronze, ndarira, simbi isina tsvina, uye nickel-cobalt alloys, pamwe chete ne tungsten, molybdenum, uye tantalum. Iyo Powder Metal process inosanganisira kusanganisa simbi dzakasiyana kugadzira akasiyana alloys akarongedzerwa kune yako application zvinodiwa. Isu tinogona kukubatsira mukugadzira wega-lubrication, corrosion resistance, uye humwe hunhu sechikamu chakakosha chemaitiro ekugadzira kuwedzera kusimba uye kuoma hunhu. Tinogona kudzvanya zvimiro zvakaomarara tichishandisa iyi yakasarudzika misanganiswa yesimbi poda pamitengo yekugadzira inosvika zana zvidimbu paminiti.

Kudzvanya
Inoiswa mu vertical hydraulic kana mechanical press iyo inoiswa mumudziyo wesimbi kana carbide die kana alloy yakakodzera yehupfu yasanganiswa. JIEHUANG inogona kudzvanya zvikamu zvine anosvika mana mazinga akajeka eruzivo rwakanaka. Zvichienderana nehukuru uye density zvinodiwa, nzira iyi inoshandisa 15-600MPa kudzvanywa kugadzira "girinhi" zvikamu zvine ese anodiwa geometric maitiro ekupedzisira dhizaini. Nekudaro, hapana chikamu chaicho chekupedzisira zviyero kana maitiro ayo emuchina aripo panguva ino. Iyo inotevera kupisa kurapwa, kana "sintering," nhanho inopedzisa izvo zvinhu.
Metal sintering (sintering process in powder metallurgy)
Zvidimbu zvakasvibirira zvinodyiswa muchoto chinopisa kudzamara vasvika kune anodiwa ekupedzisira masimba, densities, uye dimensional kugadzikana. Mukati mekuita sintering, tembiricha dziri pazasi pekunyungudika kwechikamu chikuru chehupfu chechikamu chinopisa munzvimbo yakadzivirirwa kuti ibatanidze mamorekuru zvidimbu zvesimbi zvinoumba chikamu.
Saizi uye simba rematanho anonongedza pakati peakamisikidzwa zvimedu zvinokura kuwedzera chikamu chehunyanzvi hunhu. Kuti usangane nechikamu chekupedzisira maparamita, sintering inogona kudzikira, kuwedzera, kunatsiridza conductivity, uye/kana kuita kuti chikamu chiome zvichienderana nemaitiro ekugadzira. Muchoto chinopisa, zvikamu zvinoiswa pane inoenderera mberi uye zvinotakurwa zvishoma nezvishoma kuburikidza nemakamuri echoto kuita mabasa makuru matatu.
Kuti abvise mafuta asingadiwi akawedzerwa kuhupfu panguva yekugadzirisa, zvidimbu zvinotanga kupisa zvishoma nezvishoma. Zvikamu zvinotevera zvinoenda kunzvimbo yekupisa kukuru kwechoto, uko hunhu hwekupedzisira hwezvikamu zvinotemerwa patembiricha inodzorwa kubva pa1450 ° kusvika 2400 °. Nekunyatso kuenzanisa mamiriro ekunze mukati mekamuri iyi yevira, mamwe magasi anowedzerwa kuderedza maokisidhi aripo uye kumisa kuwedzera oxidation yezvikamu panguva ino yekupisa kwakanyanya. Kuti vapedze zvidimbu kana kuti vagadzirire chero mamwe maitiro, ivo vanozopedzisira vapinda mukamuri yekutonhodza. Zvichienderana nemidziyo inoshandiswa uye ukuru hwezvikamu, kutenderera kwese kunogona kutora maminetsi makumi mana nemashanu kusvika maawa 1.5.
Post-processing
Kazhinji, thesintering zvigadzirwainogona kushandiswa zvakananga. Nekudaro, kune zvimwe zvigadzirwa zvesimbi sinter zvinoda kurongeka kwepamusoro uye kuomarara kwakanyanya uye kusapfeka, kurapwa kwepost-sintering kunodiwa. Kugadzirisa-kumashure kunosanganisira kudzvanya chaiko, kukunguruka, kuburitsa, kudzima, kudzima pamusoro, kunyudzwa kwemafuta, uye kupinza.
Surface kurapwa maitiro ehupfu metallurgy
Unogona kusangana nehupfu metallurgy zvigadzirwa,upfu metallurgy giyaizvo zviri nyore kuita ngura, zviri nyore kukwenya, nezvimwewo, kuitira kuvandudza kupfeka kuramba, ngura kuramba, kushorwa uye kuneta simba kwehupfu metallurgy zvikamu. Jiehuang ichaita kurapa pamusoro pehupfu metallurgy zvikamu, izvo zviri kuita kuti nzvimbo yayo iwedzere kushanda, uye zvakare kuita kuti nzvimbo yacho iwedzere kusimba. Saka ndedzipi mapoda metallurgy pamusoro pekurapa maitiro?
Kune mashanu akajairika maitiro ekurapa pamusoro pehupfu metallurgy:
1.Coating:Kupfekedza chidimbu chezvimwe zvinhu pamusoro peiyo yakagadziriswa poda metallurgy zvikamu pasina chero maitiro emakemikari;
2.Mechanical deformation nzira:Kumusoro kwezvikamu zvehupfu zvesimbi zvinofanirwa kugadzikiswa zvinokanganiswa nemuchina, kunyanya kugadzira kudzvanyirira kwasara kushushikana uye kuwedzera kusimba kwepasi.
3.Kemikari kupisa kurapwa:zvimwe zvinhu zvakadai seC uye N zvinopararira mukati mepamusoro pezvikamu zvakarapwa;
4.Surface heat treatment:kuchinja kwechikamu kunoitika kuburikidza nekuchinja kwe cyclic yekushisa, iyo inoshandura microstructure yepamusoro pechikamu chakarapwa;
5.Surface chemical treatment:makemikari anoita pakati pepamusoro pehupfu metallurgy chikamu chinofanira kurapwa uye chekunze reactant;
RUHWERE HWENYU HWEMETAL PARTS NDIKO KUNYANYA KWEDU KUTI AKASIYANA AKASIYANA AMAIndustry. ZVIGADZIRO ZEDU ZVAKAKOdzera ZVINHU ZVOSE, KUSIKIRA ZVINOREMERA DUTY SIMBA ZVINHU ZVINHU UYE ZVINHU ZVINHU ZVINHU ZVINHU ZVINOGONA.
