Kev tsim cov txheej txheem ua npuas dej
Mar 02, 2022
Kev npaj ntawm hlau ua npuas ncauj muaj xws li hmoov metallurgy thiab electroplating. Lub qub yog npaj los ntawm kev ntxiv foaming tus neeg sawv cev rau molten hlau kom tau hlau ua npuas ncauj; tom kawg yog replicated rau ntawm pob txha ntawm polyurethane ua npuas ncauj los ntawm electrodeposition.
Cov hmoov metallurgy txoj kev los tsim ua npuas ncauj hlau yog ntxiv ib tus neeg ua npuas ncauj (xws li NH4Cl) rau cov hmoov, thiab tus neeg sawv cev foaming volatilizes thaum sintering, tawm hauv qhov pores. Electrochemical deposition txoj kev yuav siv tau los npaj foamed hlau nrog zoo li pores thiab porosity txog li 95 feem pua, nrog rau cov ntaub ntawv ua npuas ncauj nrog Cu, Ni, NiCrFe, ZnCu, NiCu, NiCrW, NiFe thiab lwm yam hlau thiab alloys li pob txha. Cov hlau electrochemically tso rau ntawm lub cev ntxeem tau yog sintered los txuas cov khoom tso rau hauv tag nrho, thiab lub zog mus txog qhov xav tau high-porosity ua npuas ncauj hlau.
