Kev sim cov txiaj ntsig ntawm ntub cua sov electroplating ntawm hluav taws xob cua sov raj
Daim duab 1 thiab daim duab 3 qhia txog cov kev hloov hauv hluav taws xob tiv thaiv lub sij hawm ntawm cov qauv coj mus kuaj ntawm tooj liab hmoov, flake silver hmoov, thiab nyiaj plated tooj liab hmoov thaum lub sij hawm ntub cua sov sim ntawm 60 degree txheeb ze av ntawm 100 feem pua. Qhov kev tiv thaiv ntawm tooj liab hmoov conductive qauv tau nce los ntawm ze li ntawm 5 zaug hauv 24 teev, thiab nws tau dhau los ua tsis zoo tom qab peb hnub. Qhov tsis kam ntawm cov hmoov hmoov conductive piv txwv txo qis hauv 24 teev, thiab tom qab ntawd tseem tsis tau hloov pauv. Nyiaj nyob rau hauv silver plated tooj liab hmoov ua raws li ib tug conductive txoj kev, yog li ua tau raws li qhov yooj yim conductivity stability li nyiaj.
Thaum cov hmoov hmoov cov ntsiab lus ntawm cov qauv coj mus kuaj yog 63 feem pua, qhov kev tiv thaiv tuaj yeem ncav cuag qhov kev txiav txim ntawm 10-3 Ω. cm. Thaum cov hmoov hmoov cov ntsiab lus yog 75 feem pua, cov resistivity yuav raug txo mus rau 4 × 10－4Ω.cm; Thaum cov hmoov tooj liab cov ntsiab lus ntawm cov qauv coj mus txog 75 feem pua , lub ntim resistivity tsuas yog txo mus rau 10-3 Ω. cm. Thaum cov hmoov tooj liab cov ntsiab lus nce mus txog 80 feem pua, nws kuj yog ib qho nyuaj los txo cov resistivity rau 10-4 Ω. cm; Tus kheej ua nyiaj plated tooj liab hmoov hauv peb lub chaw kuaj pom zoo conductivity. Thaum cov ntsiab lus nyiaj yog 23 feem pua , nws cov conductivity yog qhov pib zoo ib yam li cov nyiaj hmoov conductive nplaum. Lub resistivity ntawm cov qauv conductive muaj 75 feem pua ntawm cov nyiaj plated tooj liab hmoov yog 5 × 10－4Ω.cm. Kev tsim cov kab hluav taws xob sib txuas los ntawm kev sib cuag ntawm cov khoom siv hluav taws xob yog qhov yuav tsum tau ua ua ntej rau cov khoom siv hluav taws xob conductive [6]. Lub stability ntawm cov nyiaj nyob rau hauv cov huab cua thiab lub siab conductivity ntawm Ag2O txiav txim siab tias ib tug conductive network yuav tsum tau tsim nrog tsawg dua cov ntsiab lus nyiaj; Copper hmoov yog yooj yim oxidized nyob rau hauv cov huab cua, thiab qhov me me particle loj, lub oxidation sai dua. Ntxiv mus, cov txheej txheem kho kuj tseem yuav ua rau qee qhov chaw oxidation ntawm cov hmoov tooj liab. Yog li ntawd, conductive tooj liab hmoov kuaj nrog tib qhov kev faib ua feem muaj hluav taws xob ntau dua. Silver particles nyob rau hauv silver plated tooj liab hmoov yog uniformly coated rau ntawm tooj liab nto. Thaum ib txoj kev conductive yog tsim, ib tug network ntawm conductive raws yog tsim los ntawm cov nyiaj, yog li nyiaj plated tooj liab hmoov exhibits zoo conductivity.
