Yuav ua li cas txhim kho qhov ntom ntawm cov hmoov metallurgy qhov chaw?
Qhov ntom ntawm cov hmoov metallurgy qhov chaw muaj feem xyuam rau cov txheej txheem compaction ntawm hmoov metallurgy. Muaj ob qhov kev txuas tseem ceeb hauv kev ua cov hmoov metallurgy qhov chaw: nias sib sau thiab nias billet sintering. Cov txheej txheem nias yog siv cov cuab yeej tshwj xeeb thiab pwm ntawm cov hmoov metallurgy qhov chaw los nias cov khoom sib xyaw ua ke (xws li hmoov hlau, tooj liab hmoov, stainless hlau hmoov) rau hauv ib qho dawb paug nrog qee qhov kev ceev. Qhov ceev ntawm qhov khoob nyob ntawm qhov xoob packing piv thiab compressibility ntawm cov ntaub ntawv raw. Zoo hmoov metallurgy raw cov ntaub ntawv zoo heev ua rau kom qhov ceev, lub zog thiab hardness ntawm qhov chaw. Txawm li cas los xij, cov hmoov hlau metallurgy ua tshuab tsis piv rau cov casting lossis tuag casting. Raws li kev nkag siab zoo, qhov ntom ntawm cov hlau slurry tom qab txias yuav tsum tshaj qhov ntom ntawm cov hmoov nplej. Yog li ntawd, qhov ceev ntawm cov khoom ua tiav los ntawm cov hmoov metallurgy nias yog twv yuav raug hu qis dua qhov tuag casting, casting, txias taub hau thiab tig qhov chaw hauv cov txheej txheem ntau lawm. Yog li peb tuaj yeem ua dab tsi los txhim kho qhov ceev ntawm P / M qhov chaw hauv cov txheej txheem tsim khoom? Cov hauv qab no tau qhia hauv ACDPrecision Editor:
hmoov metallurgy
1, Cov txheej txheem sov compaction yog saws rau compaction. Covhmoov metallurgyraw cov ntaub ntawv thiab pwm yog rhuab mus rau ib tug tej yam kub thiab compaction. Txoj kev no tuaj yeem ua rau qhov ntom ntom ntawm 7.3 g / CM raws li cov khoom siv raw zoo dua ³.
2, Nyob rau hauv cov txheej txheem sintering, vim hais tias cov additives xws li lubricant thiab txiav tus neeg saib xyuas nyob rau hauv lub dawb paug yog dewaxed thaum lub sij hawm sintering txheej txheem ntawm hmoov metallurgy qhov chaw, pores yuav tsim nyob rau hauv cov txheej txheem no. Txhawm rau txhim kho qhov ceev ntawm qhov chaw thaum sintering, txoj kev zoo tshaj plaws yog sintering tooj liab infiltration. Ib qho nyiaj ntawm cov tooj liab ntshiab yog nkag mus rau hauv sintering billet kom sau cov pores, uas tuaj yeem nce qhov ceev mus rau 7.6g / CM ³. Nyob rau hauv ib lo lus, nws yuav tsum tshaj 7.9g / CM ntawm cov ntaub ntawv thiab qhov chaw ³ Qhov ceev ntawm yog tsis yooj yim sua.
Thib ob, hmoov metallurgy ua qhov chaw muaj ntau yam ua nrog cov kev cai ntawm cov khoom. Piv txwv li, cov roj bearing yuav tsum ceev ntawm 6.3 g / CM ³ Txog yog txaus, vim hais tias cov seem uas tsis muaj ntom muaj porosity loj thiab siab roj cov ntsiab lus, uas plays lub luag hauj lwm zoo nyob rau hauv nws tus kheej lubricating. Thiab cov lus qhia, piston, hauv qab valve thiab kho lub cev hauv lub tsheb poob siab absorber ntawm cov hmoov hlau metallurgy feem ntau yuav tsum muaj qhov ceev ntawm 6.6g / CM vim qhov kev siv zoo ³ Tsuas yog ua. Tsis tas li ntawd, cov khoom siv dav siv P / M kis tau tus mob thiab lub zog, tshwj xeeb tshaj yog cov tsav tsheb tsav, yuav tsum muaj qhov ceev ntawm 6.9 g / CM vim lawv cov kabmob siab thiab lub zog hnyav ³ Hauv qhov no, kev siv lub hom phiaj ntawm cov khoom tuaj yeem ua tiav. thiab cov kev cai thiab kev ntsuas yuav ua tau raws li.
