Cov txheej txheem ua li cas yog hmoov metallurgy?

Hmoov metallurgy yog txheej txheem thev naus laus zis uas tsim cov hlau los yog siv cov hmoov hlau ua cov khoom siv raw, tom qab tsim thiab sintering, los tsim cov ntaub ntawv hlau, cov khoom sib xyaw thiab ntau yam khoom.

Hmoov metallurgy txheej txheem
1. Kev npaj hmoov thiab compression molding

Feem ntau siv tshuab pulverization, atomization, lub cev thiab tshuaj txoj kev los npaj hmoov.Cov hmoov npaj yog sieved thiab tov, cov ntaub ntawv yog uniformly tov thiab tsim nyog plasticizers ntxiv, thiab ces compressed rau hauv cov duab.Cov atoms ntawm cov hmoov hmoov yog cov khoom-theem diffusion thiab mechanical occlusion, kom cov khoom sib xyaw ua ke rau hauv ib qho tag nrho nrog lub zog..Qhov siab dua, qhov ntau dua qhov ntom ntawm qhov thiab qhov sib txuas ntawm lub zog nce.Qee zaum txhawm rau txo qhov siab thiab nce qhov ceev ntawm qhov chaw, cov txheej txheem kub isostatic nias kuj tseem siv tau.

2. Sintering
Qhov nias yog muab tso rau hauv lub qhov cub kaw nrog qhov txo qhov cua rau sintering, thiab qhov kub ntawm sintering yog li ntawm 2/3 mus rau 3/4 npaug ntawm melting point ntawm lub hauv paus hlau.Vim tias qhov sib txawv ntawm ntau hom atoms ntawm qhov kub thiab txias, qhov txo qis ntawm cov oxides ntawm cov hmoov av thiab recrystallization ntawm cov hmoov deformed, cov hmoov hmoov sib xyaw ua ke, uas txhim kho lub zog ntawm cov hmoov metallurgy cov khoom thiab tau txais ib qho kev sib txawv. qauv zoo ib yam li cov alloys.Tseem muaj qee qhov me me hauv qhov sintered, uas yog cov khoom ntxeem tau.
Peb, tom qab ua tiav
Nyob rau hauv ib txwm muaj xwm txheej, sintered qhov chaw tuaj yeem ua tiav qhov kev ua tau zoo thiab tuaj yeem siv ncaj qha.Tab sis qee zaum, qhov tsim nyog tom qab ua tiav yog xav tau.Piv txwv li, precision nias kho tuaj yeem txhim kho qhov ceev thiab qhov tseeb ntawm qhov chaw;quenching thiab nto quenching kev kho mob ntawm hlau-raws li hmoov metallurgy qhov chaw tuaj yeem txhim kho lawv cov khoom siv kho tshuab;roj immersion los yog immersion rau lubrication los yog corrosion kuj.Cov kua roj nplua nyeem;infiltration kev kho mob ntawm infiltrating tsawg melting point hlau mus rau hauv lub pores ntawm ib feem yuav txhim kho lub zog, hardness, plasticity los yog tej yam toughness ntawm ib feem.
Hmoov metallurgy qhov chaw yog dav siv nyob rau hauv ntau yam lag luam: tsheb kev lag luam, synchronizer hubs, synchronizer rings, pulleys, synchronizers;ntau yam bearings, hmoov metallurgy zog, hlau structural qhov chaw, thiab lwm yam yog dav siv nyob rau hauv machinery manufacturing
