Nkag siab Powder Metallurgy Parts: Txheej Txheem thiab Khoom

Hmoov hlau qhov chaw

 

Hmoov metallurgy sawv cev rau kev tsim cov txheej txheem uas hloov cov hmoov hlau ua cov khoom siv los ntawm cov kauj ruam meej. Txoj kev taug pib nroghmoov hlautsim los ntawm kev sib tsoo, crushing, atomization, los yog tshuaj tiv thaiv. Cov hmoov no tau muab sib xyaw thiab sib xyaw nrog cov binders lossis lubricants kom ua tiav cov yam ntxwv zoo.

 

Kev Tshawb Fawb Tom Qab Powder Metal Manufacturing

Kev tsim khoom tshwm sim hauv peb theem tseem ceeb. Cov hmoov hlau tau compressed ntawm qhov siab ntawm 150 MPa thiab 700 MPa. Cov kauj ruam tom ntej no suav nrogsintering - txheej txheem kev kho cua sovuas tshwm sim hauv qab cov hlau melting point. Qhov kev kho mob no txuas cov hlau hais ua ke mus tas li thiab tsim cov khoom siv tau zoo.

 

Cov khoom tseem ceeb ntawm hmoov Metallurgy Cheebtsam

Cheebtsam ua los ntawm hmoov metallurgy qhia tau hais tias zoo kawg li versatility nyob rau hauv lawv cov khoom siv. Cov khoom no ncav cuag qhov kawg tensile lub zog nce mus txog 900 N / mm² txoj cai tom qab sintering. Lub zog tuaj yeem mus txog 1200 N / mm² tom qab kev kho cua sov. Lub compressive yield kev ntxhov siab nce mus txog 510 N / mm² tom qab sintering thiab dhia mus rau 1250 N / mm² tom qab kev kho cua sov.

 

Ntom thiab porosity xav

Tswj porosity teev hmoov metallurgy sib nrug los ntawm lwm cov txheej txheem. Cov neeg tsim khoom tuaj yeem tsim cov khoom nrog cov txheeb ze ntom ntom ntawm 75% mus rau ntau dua 95%, thaum forgings yuav ntau dua 99% ntom. Sintered compacted qauv feem ntau qhia 20-30% porosity theem. Tus lej no tuaj yeem ncav cuag 50-60% rau sintered xoob cov qauv.

Cov kws tshaj lij tuaj yeem tswj qhov pore loj thiab kev faib tawm nrog kev ua tau zoo. Qhov no ua rau cov txheej txheem zoo meej rau cov ntawv thov uas xav tau kev pom muaj peev xwm tshwj xeeb. Kev siv cov qauv siv feem ntau xav tau qhov chaw nrog cov txheeb ze ntom ntom ntawm 80% mus rau 95% kom tswj tau cov khoom siv kho kom zoo. Cov khoom siv ntom ntom ntau dua feem ntau ua tau zoo dua mechanically.
