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 kuumba(MIM) inoshandisa simbi hupfu seyakagadzirwa kugadzira zvidimbu zvidiki zvesimbi zvine maumbirwo akaomarara nenzira yepurasitiki jekiseni rekuumba.Pane zveMIM simbi jekiseni kuumba zvinhu, 70% yezvinhu zvinoshandiswa iye 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 njanji, zvemagetsi ruzivo tekinoroji indasitiri, muchina wekuvaka uye zvimwe midziyo kugadzira uye kugadzirisa uye migodhi, oiri negasi zviwanikwa zviwanikwa, 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, etc.

Mukana wepoda simbi yekugadzira magineti zvinhu ndezvekuti inokwanisa kugadzirira magineti muhukuru hwenzvimbo imwe chete, kuwana inopindirana yakatarisana neiyo magineti poda panguva yekutsikirira, uye yakananga kuburitsa yakakwira magineti chigadzirwa chemagetsi padhuze 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 seCo, Cr, W, Mo, Al, Ti, Nb, Ta, etc. Iyo ine yakanakisa kusimba kwekushisa kwepamusoro, kuramba kuneta uye kupisa kwegora rekudzivirira 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 chinopa zano pamusoro pezvinhu zvinoenderana nemidziyo yeupfu yako yesimbi zvikamu.Iyo yakakura yakawanda yezvigadzirwa zvinogona kushandiswa kugutsa zvaunoda maererano nemutengo, kusimba, kutonga kwemhando, uye chaiyo mashandisirwo ndeimwe yemabhenefiti makuru. yekushandisa hupfu simbi kugadzira zvinhu.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.JIEHUANGinogona kudhinda zvikamu zvine mazinga anosvika mana akasiyana 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.

Surface kurapwa maitiro ehupfu metallurgy

Unogona kusanganaupfu metallurgy zvigadzirwa, poda metallurgy giya zviri nyore kuita ngura, zviri nyore kukwenya, nezvimwewo, kuitira kuti uvandudze kusagadzika kwekupfeka, kupikisa ngura, kushomeka kwemarara uye kuneta kusimba kwepoda metallurgy (giya) zvikamu.Jiehuang ichaita kurapa pamusoro pehupfu simbi zvikamu, izvo zviri kuita kuti nzvimbo yayo ishande zvakanyanya, uye zvakare kuita kuti nzvimbo yacho ive yakawanda.Saka ndedzipi mapoda metallurgy pamusoro pekurapa maitiro?

Kune mashanu akajairika maitiro ekurapwa kwepamusoro mukatipoda metallurgy kugadzira maitiro:

1. Kupfekedza: Kupfekedza chidimbu chezvimwe zvinhu pamusoro pezvikamu zvehupfu zvakagadziriswa pasina makemikari anoita;

2. Mechanical deformation method: Nzvimbo yepoda metallurgy zvikamu zvinogadziriswa zvakasvibiswa nemagetsi, kunyanya kuunza compressive residual stress uye kuwedzera kusimba kwepamusoro.

3. Kemikari kupisa kurapwa: zvimwe zvinhu zvakadai seC uye N zvinopararira mukati mepamusoro pezvikamu zvakarapwa;

4. Kurapa kwekupisa kwepamusoro: kuchinja kwechikamu kunoitika kuburikidza nekuchinja kwemhepo yekushisa, iyo inoshandura microstructure yepamusoro pechikamu chakabatwa;

5. Surface kemikari kurapwa: makemikari anoita pakati pepamusoro pehupfu metallurgy zvikamu kuti zvigadziriswe uye kunze reactant;
