Kev Piav Qhia: J506NiMA thiab J507NiMA yog cov hlau electrodes uas nqus tau dej noo uas muaj hydrogen tsawg heev uas muaj cov hlau alloy tsawg. Cov hlau uas tau tso rau hauv cov hlau no muaj cov yas zoo heev, tawv tsis kub thiab tsis tawg, thiab tuaj yeem vuam tau rau txhua qhov chaw. Cov txheej no tiv taus kev nqus dej noo. Tom qab ci cov electrode ntawm 400°C x 1 teev thiab nres rau hauv ib puag ncig uas muaj cov av noo ≥ 80% rau 4 teev, cov dej noo ntawm cov txheej no tseem ua tau raws li qhov yuav tsum tau siv.
Daim Ntawv Thov: Nws yog siv rau kev vuam ntawm cov roj platforms, nkoj, cov hlab ntsha siab, thiab lwm yam qauv ua los ntawmcov hlau carbon thiab cov hlau tsis tshua muaj hlau.
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau vuam (%):
| C | Mn | Si | Ni | S | P | |
| Tau lees paub | ≤0.12 | ≥1.00 | ≤0.50 | ≤0.60 | ≤0.035 | ≤0.040 |
Cov khoom siv kho tshuab ntawm cov hlau vuam:
| Khoom sim | Lub zog tensile Mpa | Lub zog tawm los Mpa | Kev ntev % | Tus nqi cuam tshuam (J) -46 ℃ |
| Tau lees paub | ≥490 | ≥390 | ≥22 | ≥27 |
Cov ntsiab lus hydrogen diffusion ntawm cov hlau tso: ≤5.0mL / 100g (gas chromatography lossis mercury txoj kev)
Cov dej noo ntawm cov electrode coatings: ≤0.30%
Kev tshuaj xyuas X-ray: Kuv qib
Pom zoo tam sim no:
| Txoj kab uas hla ntawm tus pas nrig | 2.5 | 3.2 | 4.0 | 5.0 |
| Vuam Tam Sim No | 60 ~ 90 | 90 ~ 120 | 140 ~ 180 | 170 ~ 210 |
Daim Ntawv Ceeb Toom:
1. Lub electrode yuav tsum tau ci rau 1 teev ntawm 350 ~ 400 ℃ ua ntej vuam ua haujlwm;
2. Nws yog ib qho tseem ceeb uas yuav tsum tau ntxuav cov xeb, roj nplai, dej, thiab cov khoom tsis huv ntawm cov khoom vuam ua ntej vuam;
3. Siv txoj kev vuam luv luv thaum vuam. Txoj kev vuam nqaim yog qhov tsim nyog.
