Kunzwisisa Powder Metallurgy Zvikamu: Maitiro uye Zvivakwa

Upfu Metal Zvikamu

 

Powder metallurgy inomiririra yakaomesesa kugadzira iyo inoshandura simbi hupfu kuita zvinhu zvakasimba kuburikidza nematanho chaiwo. Rwendo runotanga nesimbi upfuyakagadzirwa nekukuya, kupwanya, atomization, kana kuita kwemakemikari. Mapoda aya anosanganiswa uye anosanganiswa nemabhainda chaiwo kana mafuta ekuzora kuti awane hunhu hwakakodzera.

 

Sayenzi Kuseri Kweupfu Metal Kugadzira

Kugadzirwa kunoitika mumatanho matatu akakosha. Iyo simbi poda inotsikirirwa pakumanikidzwa pakati pe150 MPa ne700 MPa. Danho rinotevera rinosanganisirasintering - nzira yekurapa kupisaizvo zvinoitika pasi pekunyungudika kwesimbi. Kurapa uku kunobatanidza zvimedu zvesimbi pamwechete zvachose uye zvinogadzira zvinhu zvakasimba, zvinoshandisika.

 

Yakakosha Material Properties yePowder Metallurgy Zvikamu

Zvikamu zvinogadzirwa kuburikidza nehupfu metallurgy zvinoratidza kusiyanisa kunoshamisa muzvinhu zvavo zvezvinhu. Aya mativi anosvika ekupedzisira ekusimba kwesimba mazinga anosvika 900 N/mm² achangopedza sintering. Simba rinogona kukwira kusvika pa1200 N/mm² mushure mekurapwa kwekupisa. Kudzvanya kwegoho kunosvika pa510 N/mm² mushure mekunyura uye kusvetuka kusvika pa1250 N/mm² zvichitevera kurapwa kwekupisa.

 

Density uye Porosity Kufunga

Inodzorwa porosity inoisa poda metallurgy kubva kune mamwe maitiro. Vagadziri vanogona kugadzira zvikamu zvine hukama kubva pa75% kusvika pamusoro pe95%, nepo forgings inogona kudarika 99% density. Sintered compacted samples inowanzoratidza 20-30% porosity mazinga. Iyi nhamba inogona kusvika 50-60% ye sintered loose samples.

Mainjiniya anogona kudzora pore saizi uye kugovera nekunyatso hunyanzvi. Izvi zvinoita kuti maitiro acho ave akakwana kune maapplication anoda chaiwo kusefa kugona. Zvimiro zvekushandisa zvinowanzoda zvikamu zvine hukama pakati pe80% kusvika 95% kuchengetedza zvakaringana zvemichina. Higher density components zvinowanzoita zvirinani mechanically.

JIEHUANG inounza hunyanzvi hwakadzama muhupfu simbi simbi maitirwo ekugadzira zvinhu zvinoenderana nemadimikira chaiwo. Unogona kubvunza timu yeJIEHUANG nezve simbi yehupfu ingashanda kune zvaunoda kugadzira. Nhungamiro yavo yehunyanzvi ichakupa mhinduro dzakakodzera nekukurumidza.

Zvinhu zvesimbi zvakagadzirwa kuburikidza nekugadzira zvinopinda yakasarudzika nzira yekugadzira. Iyi nzira inoumba simbi iine masimba ekumanikidza emunharaunda uye inogadzira zvikamu zvine kurongeka kwakasiyana. Iyo simbi inoshanduka kuburikidza nekusando, kudzvanya, kana kukungurutsa nzira patembiricha chaiyo.

 

Traditional vs. Mazuvano Forging Methods

Vapfuri vechivanhu vaishandisa marasha kana marasha maforoji ane maturusi akareruka senge sando nenyemba. Kugadzira kwemazuva ano kwakashanduka zvakanyanya uye ikozvino inoshandisa tekinoroji yepamberi senge magetsi induction furnaces uye gasi forges inopa zvirinani tembiricha. Nzira dzanhasi dzinosanganisira hydraulic presses, pneumatic sando, uye komputa-inobatsira dhizaini software kuti ive nechokwadi chekugadzirwa chaiko.

The forging process inoitika pamatembiricha aya:

• Kupisa kwekugadzira: Kunoitwa pakati pe950-1250 ° C, iyo inobvumira kuumbwa kwakanaka nekushomeka kwesimba zvinodiwa.
• Kugadzira kunodziya: Kunoitwa pa750-950 ° C, ichipa chiyero pakati pekuumbwa uye nemazvo.
• Cold forging: Inourayiwa pakamuri tembiricha inosvika 150°C, ichipa mhedziso yepamusoro.

 

Maumbirwo ezviyo uye Zvigadzirwa zveMichina

Chimiro chemukati cheMetal chinoshanduka zvakanyanya panguva yekugadzira kuburikidza nekuyerera kwezviyo - inotungamirwa inotungamirwa yesimbi zviyo uye inclusions. Iyo alloy kuumbwa kwakakosha madhairekitori anobatsirwa kubva kune epamusoro mechanicha zvivakwa nekuda kweiyi yakasarudzika hunhu.

Anisotropic properties inobuda kubva mukuita uku, zvinoreva kuti mechanical maitiro anoshanduka zvichienderana nekutarisa zviyo. Crack resistance zvivakwa zvinoratidza kuvandudzwa kunoshamisa zvichienderana nekuyerera kwezviyo. Iyo yakanakisa kurongeka inoitika pasi pemamiriro chaiwo:

• Kunyanya kushushikana kukuru kunogadzirisa perpendicular kune inogona kutsemuka nzvimbo
• Mitsetse yezviyo-yekuyerera yakatarisa zvine hungwaru kuti iwedzere simba

Mativi akaumbwa anokunda mukusimba kuburikidza ne:

• Kubviswa kwemukati gasi homwe uye voids
• Zvirinani kuneta simba uye simba rekudzivirira
• Kupindirana kwekupindura kwekupisa kurapwa
• Uniform machinability mukati mekugadzira inomhanya

JIEHUANG inopa hunyanzvi muhupfu simbi zvigadziriso seimwe nzira yemaitiro echinyakare ekugadzira nzira dzevagadziri vanoda yakakwana yezvinhu zvivakwa.

 

Kuenzanisa Kwesimba: Powder Metal Parts vs. Forged Components

Kuyedzwa kunoratidza mutsauko wakajeka mukuumbwa uyeupfu simbi zvikamuita kana zvasvika kune mechanical properties. Tsvagiridzo yemazuva ano inoratidza kuti zvikamu zvesimbi zvakaumbwa zvinoita zvirinani pane zvikamu zvesimbi zvehupfu mumayero akakosha esimba.
