Ntxuav thiab tom qab -kev kho mob
Tom qab nyiaj plating, cov kauj ruam hauv qab no tau ua nyob rau hauv ib ntus:
1. Peb yaug nrog dej deionized kom tshem tawm cov nyiaj dawb ions
2. Ob qhov ntxuav nrog ethanol kom tshem tawm cov organic residues
3. Nqus kom qhuav qhov cub ntawm 80℃rau qhov kub thiab txias tas li lub cev qhuav dej
4. Sieve thiab faib (200-400 mesh)
Kev txhim kho kev ua haujlwm
Los ntawm kev ua kom zoo ntawm cov txheej txheem tiv thaiv kev sib xyaw ua ke (gelatin thiab polyvinylpyrrolidone compound), qhov sib xws ntawm cov nyiaj txheej tuab yog txhim kho ntau dua 20%. Kev txhim kho iav hmoov nthuav tawm cov hauv qab no hauv cov khoom siv nyiaj ua haujlwm:
Kev tiv thaiv tiv thaiv raug txo kom qis dua 0.5Ω·cm
Nyiaj txheej adhesion mus txog qib 5B (ASTM D3359 tus qauv)
Tsis muaj nyiaj txheej txheej tom qab siab -kub sintering
