Hauv kev npaj cov txheej txheem ntawm sintered ntxeem tau titanium daim hlau, thiaj li yuav ua tiav qhov sib npaug ntawm qhov pore loj thiab cov khoom siv kho tshuab, cov hauv qab no yuav tsum tau xav txog:
Kev xaiv cov khoom siv raw: Xaiv cov ntaub ntawv tsim nyog tuaj yeem tswj qhov pore loj thiab porosity ntawm titanium phaj, yog li paub txog cov kev cai ntawm huab cua permeability thiab txhua yam khoom. Feem ntau hais lus, cov ntaub ntawv raw nrog cov me me me tuaj yeem tsim cov sintered ntxeem tau titanium phaj nrog me pore loj, thaum raw khoom nrog coarser particle loj tuaj yeem tsim sintered ntxeem tau titanium phaj nrog loj pore loj.
Hom thiab tus nqi ntawm cov khoom ntxiv: Cov khoom ntxiv tuaj yeem hloov pauv tus cwj pwm sintering ntawm cov ntaub ntawv raw thiab cuam tshuam rau qhov porosity thiab pore loj ntawm titanium daim hlau. Feem ntau hais lus, ntxiv qhov tsim nyog ntawm flux tuaj yeem txo qhov kub thiab txias thiab txhawb kev sib txuas ntawm cov khoom, kom tau txais sintered ntxeem tau titanium phaj nrog cov pore me me thiab qis porosity, thiab txhim kho cov khoom siv; Thaum ntxiv flux ntau dhau lawm Lub porosity siab dhau lawm, uas cuam tshuam rau cov khoom siv hluav taws xob ntawm titanium phaj.
Sintering kub thiab lub sij hawm: Lub sintering kub thiab lub sij hawm ncaj qha cuam tshuam lub pore loj thiab porosity ntawm titanium phaj. Feem ntau hais lus, sintering kub dua thiab ntev sintering lub sij hawm yuav tau txais ib tug sintered ntxeem tau titanium phaj nrog ib tug loj pore loj thiab ib tug ntau dua porosity, tab sis nws kuj yuav ua rau ib tug txo nyob rau hauv lub mechanical zog ntawm lub titanium phaj. Yog li ntawd, kev xaiv ntawm sintering kub thiab lub sij hawm yuav tsum tau hnyav raws li cov kev thov tshwj xeeb thiab kev ua haujlwm yuav tsum tau ua.
Pretreatment ua ntej sintering: Ua ntej sintering, raw cov ntaub ntawv yuav tsum tau pretreated, xws li compressed rau hauv hais, ntxuav, thiab lwm yam., kom tau raws li ib tug particle tis thiab siab compactness, yog li txhim kho cov neeg kho tshuab zog ntawm sintered titanium phaj.
Hauv cov ntsiab lus, thaum npaj sintered ntxeem tau titanium daim hlau, nws yog ib qho tsim nyog yuav tsum tau ua tib zoo xav txog kev xaiv cov khoom siv raw, hom thiab tus nqi ntawm cov additives, qhov kub thiab txias thiab lub sij hawm, thiab pretreatment ua ntej sintering kom ua tiav qhov sib npaug ntawm qhov pore loj thiab cov khoom siv tshuab. . Nyob rau tib lub sijhawm, qhov pore loj thiab porosity tsim nyog yuav tsum raug xaiv raws li cov kev thov tshwj xeeb thiab cov kev xav tau ua haujlwm kom tau txais qhov zoo tshaj plaws ntawm huab cua permeability thiab cov khoom siv tshuab, kom ua tau raws li qhov yuav tsum tau ua ntawm kev siv tswv yim.
